Thank you for choosing an APT Surge

Protective Device (SPD). The XM is a high quality,

high energy surge suppressor designed to protect

sensitive equipment from damaging transient

overvoltages. The SPD is parallel connected

such that circuit ampacity is unlimited. Proper

installation is important to maximize performance.

Please follow steps outlined herein. These

instructions are not intended to replace national or

local codes. Follow all applicable electrical codes

to ensure compliance.

XM complies with latest regulatory actions and is

UL 1449 Listed (VZCA.E321351). See National

Electrical Code (NEC

) Article 285 regarding SPDs.

XM is a Type 2 SPD, intended for installation

on the load-side of the service disconnect. We

recommend connecting via a 20-30A circuit breaker

due to 10 AWG conductors. UL 1449 safety and

performance evaluations were performed with a

30A circuit breaker. The circuit breaker serves as

a disconnect switch and provides NEC

imposed

short circuit protection to the conductors in Type

2 applications.

Simplied Explanation of Operation

SPDs sense overvoltage and create a momentary

short circuit to redirect harmful surge energy to

earth ground. They reset automatically and wait

for the next surge. This is similar to the pressure

relief valve on a water heater: pressure goes up,

valve opens to relieve pressure and then resets. In

an electrical system, an SPD senses overvoltage,

shorts temporarily sending energy to ground and

then resets. SPDs are capable of repeating this

function thousands of times.

XM Series

Surge Protective Device (SPD)

INSTALLATION

Pre-Plan your installation. You need to accomplish the following:

▪ Meet all National and Local codes. (NEC

Article 285 and UL 1449 address SPDs).

▪ Conrm System voltage to SPD voltage. (120V SPD will fail instantly on 240V, 277V, etc.).

▪ Verify that the SPD’s 100kA SCCR is greater than or equal to the available fault current.

(NEC

Article 285.6 compliance).

▪ A 20-30A circuit breaker is required, having a kAIC rating equal to or greater than the

available fault current is required.

▪ Mount SPD as close to panel or equipment as possible to keep leads short. (long leads hurt

performance).

▪ Ensure leads are as short and straight as possible, including neutral and ground. If using a

breaker, use a breaker position that is close to the SPD and the panel’s neutral and ground.

▪ Make sure system is grounded per NEC

and clear of faults before energizing SPD.

(inadvertent system problem may fail SPD).

▪ Never Hi-Pot test Any SPD. (will prematurely fail SPD).

▪ Do Not Install the XM through the bottom of a NEMA 3R panel. Dripping water into the hub

& wire entry area will prematurely fail the SPD. If installing in the bottom of a 3R panel,

install threaded and watertight hardware into the SPD such that it rises above the panel’s

standing-water line.

1. Use voltmeter to check voltages and ensure correct SPD. See Data Sheet for specs & wire-outs.

2. Ensure SPD SCCR and circuit breaker kAIC ratings are equal to or greater than the available

fault current.

3. Determine Mounting method – weather resistant equipment may be required.

4. If SPD has optional Dry Contact or Flush Mount Kit, pre-plan their installation.

5. Remove power from panel/source. Conrm panel/source is deenergized.

6. Identify breaker location and SPD location. Position SPD such that LEDs are most visible.

7. Remove an appropriately sized knockout from panel.

8. Mount SPD – weather resistant applications require additional sealing, o-rings, etc. (not included).

9. Connect conductors as appropriate – short and straight as possible. (Hi-Legs are Phase B).

10. Label or mark conductors as appropriate. (neutral: white, ground: green, energized: black,

hi-leg: orange).

11. Make sure system is bonded per NEC

and is clear of hazards or faults before energizing.

(N-G bonding not per NEC

will fail SPDs: #1 cause of SPD failures).

12. Energize and conrm proper operation of green LED indicators and/or options.

Safety Disconnectors

XMs have demonstrated 100kA Short Circuit

Current Ratings (SCCR). (See UL Label markings

on each SPD or see Data Sheet for specs.) A

20-30A circuit breaker is required as overcurrent

protection for this SPD. Follow applicable codes.

This device features internal overtemperature

protection that will disconnect effected surge

suppression components at the end of their useful

life, but will maintain power to the load – now

unprotected. If this situation is undesirable for the

application, follow these instructions for replacing

the device. The XM is ultrasonically welded closed

and contains no user serviceable parts.

Voltage Rating & Application

Before installing SPD, verify by nameplate voltage

or model number that it has the same voltage

rating as the power distribution system. See

attached Data Sheet or call APT Tech Support at

(800) 237-4567 as appropriate. The SPD’s specier

or user should be familiar with the conguration and

arrangement of the power distribution system. The

system is dened by how the secondary windings

of the transformer supplying the service entrance

main or load are congured. This includes whether

or not the transformer windings are referenced

to earth via a grounding conductor. The system

conguration is not based on how any specic load

or equipment is connected to a particular power

distribution system. SPDs should be installed per

the distribution system, not per a load or motor’s

wiring connection.

For example, suppose a 480V three phase motor

appears to be connected as a 480V Delta. In

actuality, the serving distribution system might

be a 480Y/277V grounded Wye, with or without a

neutral pulled to the motor or MCC. The system

is still a 480Y/277V Wye, even though the load

is connected as a Delta. A grounded Wye has a

dened reference to ground (i.e., neutral is bonded

to ground). In contrast, some Delta systems are

ungrounded, which have no reference to ground.

SPDs on Ungrounded Systems

Caution: Ungrounded systems are inherently

unstable and can produce excessively high

line-to-ground voltages during certain fault

conditions. During these fault conditions, any

electrical equipment including an SPD, may be

subjected to voltages which exceed their designed

ratings. This information is being provided to the

user so that an informed decision can be made

before installing any electrical equipment on an

ungrounded power system.

Attention: Les systèmes non mis à la terre sont

fondamentalement instables et peuvent produire

des tensions excessives entre la ligne haute

tension et la mise à la terre lors de certaines

conditions de défaut. Durant ces conditions de

défaut, tout appareil électrique, y compris un SPD,

peut être soumis à des tensions dépassant leurs

spécications nominales. Ces renseignements

sont fournis à l’utilisateur an qu’il puisse prendre

une décision informée avant d’installer un appareil

électrique sur un système d’alimentation qui n’est

pas mis à la terre.

Connecting Optional Form C Dry Contact

Three (3) 3’ (~1m) 18 AWG wires are included

through the hub with this option. (These are

smaller than the 10 AWG SPD conductors.) Gray

is Common, red is Normally Open and blue is

Normally Closed. (We generally recommend the

Normally Closed conguration because it detects

disconnected or failed wiring whereas Normally

Open does not.) Dry Contact wires to be connected

to Class 1 circuits only.

The contact is rated 250V, 5A. Higher energy

applications require supplemental relaying. This

option monitors suppression element condition

and is not intended for use as phase loss or phase

detection monitoring.

NORMAL OPERATION

Green LED Indicators – The SPD includes two

green LED indicators per phase for redundancy

purposes. Full Protection is indicated when

both LEDs for every phase are illuminated. If

only one LED per phase is illuminated, then the

SPD is providing partial protection. If no LEDs

are illuminated, then the SPD is providing no

protection, or there is no power to the affected

phase(s).

Form C Dry Contact

Similar to the green LED above, the Dry Contact

will change state upon internal SPD failure.

UL 1283 required language concerning the

installation of EMI Filters

a) An insulated grounding conductor that is

identical in size and insulation material and

thickness to the grounded and ungrounded circuit

supply conductors, except that it is green with

or without one or more yellow stripes, is to be

installed as part of the circuit that supplies the lter.

Reference should be made to Table 250-122 of the

National Electrical Code regarding the appropriate

size of the grounding conductor.

b) The grounding conductor mentioned in item a is

to be grounded to earth at the service equipment

or other acceptable building earth ground such as

the building frame in the case of a high-rise steel-

frame structure.

c) Any attachment-plug receptacles in the vicinity

of the lter are to be of a grounding type, and the

grounding conductors serving these receptacles

are to be connected to earth ground at the service

equipment or other acceptable building earth

ground such as the building frame in the case of a

high-rise steel-frame structure.

d) Pressure terminal or pressure splicing connectors

and soldering lugs used in the installation of the

lter shall be identied as being suitable for the

material of the conductors. Conductors of dissimilar

metals shall not be intermixed in a terminal or

splicing connector where physical contact occurs

between dissimilar conductors unless the device

is identied for the purpose and conditions of use.

Maintenance

SPDs require minimal maintenance. We

recommend periodic inspection of diagnostic

indicators to ensure proper operation. We also

recommend keeping the SPD clean as appropriate.

Troubleshooting & Service

Please contact us for any service related issues.

We want to take care of any problems.

Quality SPDs withstand severe duty and attempt to

protect their load until failure. There are electrical

anomalies that SPDs cannot protect against. These

are generally Sustained Overvoltages also known

as Temporary Overvoltages (TOVs). In this context,

Sustained Overvoltages may be only a few cycles.

Failed SPDs tend to be symptoms, not root causes.

We suggest treating a failed SPD as a ‘canary in the

coalmine’ as there may be larger issues at play. As

a generalization, the single largest ‘killer’ of SPDs

is reference to ground issues. If the SPD shows

problems on startup, there is reasonable chance

of bonding/grounding/misapplication issue. This

permanently damages the unit. If not corrected, it

will happen again.

Any returns need a

Return Authorization (RA) number.
