Ground Leakage Currents

WARNING

Risk of electric shock. Can cause equipment damage, injury and death.

As with other types of high power equipment, dangerous voltages are present within the UPS and battery

enclosure even after input power has been disconnected. The risk of contact with these voltages is

minimized as the live component parts are housed behind a metal panel. Further internal safety screens

make the equipment protected to IP20 standards. Never remove panels or covers or open doors that will

expose internal components to contact.

Read and follow all warnings, cautions and safety and operating instructions to avoid serious injury or

death from electric shock. No risk exists to any personnel when operating the equipment in the normal

manner, following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and should be carried out

only by trained personnel.

AVERTISSEMENT

Risque de décharge électrique pouvant entraîner des dommages matériels, des blessures et même la

mort.

À l'instar des autres types d'équipement haute puissance, des tensions dangereuses sont présentes à

l'intérieur de l'armoire ASC et du châssis de batteries même après le débranchement de l'alimentation

d'entrée. Le risque de contact avec ces tensions est diminué, car les parties de composants sous tension

sont abritées derrière un panneau métallique. D'autres écrans de sécurité internes protègent

l'équipement en conformité avec les normes IP20. Ne retirez jamais les panneaux ou les couvercles et

n'ouvrez pas les portes donnant accès aux composants internes avec lesquels vous pouvez entrer en

contact.

Veuillez lire et suivre l'ensemble des avertissements, des mises en garde et des instructions de sécurité et

de fonctionnement afin d'éviter des blessures graves, voire la mort, pouvant être causées par une

décharge électrique. Il n'y a aucun risque pour le personnel lorsque l'équipement est utilisé normalement,

en suivant les procédures de fonctionnement recommandées.

Toutes les procédures de réparation et d'entretien de l'équipement exigent un accès à l'intérieur de

l'armoire et devraient être menées uniquement par du personnel compétent.

WARNING

Risk of electric shock from high leakage current. Can cause injury, property damage and death.

EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE INPUT SUPPLY.

Earth leakage current exceeds 3.5 mA and is less than 1000 mA.

Transient and steady-state earth leakage currents, which may occur when starting the equipment, should

be taken into account when selecting instantaneous RCCB or RCD devices.

Residual Current Circuit Breakers (RCCBs) must be selected sensitive to DC unidirectional pulses (Class

A) and insensitive to transient current pulses.

Note also that the earth leakage currents of the load will be carried by this RCCB or RCD.

This equipment must be earthed in accordance with the local electrical code of practice.

1.0 LIEBERT EXM BDC

The Liebert EXM BDC is designed to operate in UPS normal mode, static bypass mode and maintenance mode.

The Liebert EXM BDC offers 10-100kVA capacity to match the associated Liebert EXM frame offerings. Each of

the Liebert EXM BDC capacities offer optional input 208V, 220V, 480V and 600V internal transformers as well as

multiple output distribution selections.

Figure 1 Single input UPS with external Liebert EXM BDC with optional internal transformer—Typical configuration

1.1 Normal (UPS) Mode

While the Liebert EXM BDC is in Normal mode (MBB open; BIB/MIB closed), the UPS is supplying the connected

load with continuous, high-quality AC power. In this mode of operation, the load is protected by the UPS.

1.2 Maintenance Mode

When the Liebert EXM BDC is in Maintenance mode (MBB closed; BIB/MIB open), it provides an alternate path

for power to the connected equipment should the UPS need to be taken out of service for limited maintenance

or repair. In this mode of operation, no power is supplied to the UPS and the load is NOT protected by the UPS.

1.5.1 Floor Installation

If the Liebert EXM BDC is to be placed on a raised floor, the UPS should be mounted on a pedestal that will

support the equipment point loading. Refer to the Liebert EXM UPS manual, SL-25648 or SL-25650, to design

this pedestal.

1.5.2 Cable Entry

Cables can enter the Liebert EXM BDC from the top or bottom through removable metal plates.

Some plates have factory-punched holes and others are designed to allow the personnel to punch holes for

fitting and securing the conduit. Once the conduit holes are punched, these plates should be reattached to the

UPS. The conduit size and wiring method must be in accordance with all local, regional and national codes and

regulations, including NEC ANSI/NFPA 70.

1.5.3 Optional Cabinets

The Liebert EXM BDC must be bolted to right side of the Liebert EXM (see Figure 10).

The Liebert EXM BDC must be cabled and bolted to the Liebert EXM before the UPS and bypass distribution

cabinet are moved into their final position. Connect input wiring to the Liebert EXM BDC ONLY after the units are

internally cabled and positioned.

Battery cabinets may be bolted only to the left side of the Liebert EXM; see Figure 10.

WARNING

Risk of heavy units tipping over while being moved. Can cause property damage, injury and death.

The Liebert EXM BDC and battery cabinets must be properly prepared and secured for lifting. Improper

lifting may cause the cabinets to fall, causing equipment damage, personal injury and death.

Vertiv recommends lifting the units with one of the following methods:

• Installing four eyebolts in the factory-fabricated holes, one at each corner of the unit, attaching

cables or similar strapping to the eyebolts and lifting with a suitable mechanism.

• Placing suitable straps on the Liebert EXM BDC or battery cabinet. The straps must go under the

unit to be lifted.

AVERTISSEMENT

Le centre de gravité élevé des appareils présente un risque de renversement lors des déplacements,

pouvant entraîner des dommages matériels, des blessures et même la mort.

Les armoires Liebert EXM BDC et de batterie doivent être correctement préparées et sécurisées avant

d’être levées. Un mauvais levage peut faire tomber les armoires, causant des dommages à l'équipement,

des blessures, voire la mort.

Vertiv recommande de soulever les unités en suivant l'une des méthodes suivantes :

• En installant quatre anneaux de levage dans les ouvertures fabriquées en usine, avec un anneau

dans chaque coin de l’appareil, pour ensuite fixer les câbles ou sangles aux anneaux afin d'effectuer

le levage à l'aide d'un mécanisme approprié.

• En plaçant des sangles convenables sur l'armoire Liebert ou de batterie. Les sangles doivent

passer sous l'unité à soulever.

NOTE

When installing the UPS, the customer must provide a disconnect with overcurrent protection at the output

of the UPS.
