nVent.com | 7

EM2-CM-MAT HEATING SYSTEM (1)

The heating mat “EM2-CM-Mat” is a constant

wattage heating device for a permanent

installation in screed or sand under paving slabs.

It is a 230Vac system regulated by a control unit.

(Control unit provided separately.)

EM2-CM-Mat is a preterminated and ready to

install heating mat with 1 cold lead connection

and a power output of approx. 300 W/m² or 25

W/m of heating cable. All mats have a width of

0.6 m and are available in lengths from 2 m up

to 21 m. The cold lead cable has a length of 4 m,

and should be installed in a conduit.

The minimum cable spacing is 10 cm. With 10

cm spacing the power output will be 300 W/m².

Spacer, Junction box (4) and

supply lead (9)

When it is necessary to loosen the heating cable

from the mat, the plastics strips (VIA-Strips-PL)

will help maintain the correct spacing (10 cm).

Extension of the cold leads needs to be done in a

junction box. The connection between the control

panel and the junction box is made by a suitable

supply lead.

Controller (8)

nVent offers control units specially designed

for ramp heating applications. They incorporate

combined temperature and moisture sensors to

ensure efficient operation of the system.

Panels (7)

nVent offers a range of standard panels

specifically designed for ramp heating

applications. Each panel contains a built in

control unit, plus circuit breakers and a residual

current device (rcd).

ADDITIONAL ITEMS

Conduits (5, 6)

Conduits (not included) are required to

protect the

• cold lead

• sensor connection lead.

Electrical Control Equipment

If nVent standard panels are not used, further

items will be required to complete the system:

• contactors

• circuit breakers

• residual current device (rcd) 30 mA.

Covered

area

Lay the heating cable right

up to the drain-off gutter.

Covered area

Also heat the surfaces on

which braking will occur, e.g.

before a barrier or a magnetic

card reader.

Also heat

the drain-off

gutter.

Also heat the

covered area of the

entry, as incoming

vehicles can bring in

snow.

Do not run the

heating mat over

expansion joints.

Storage of the mat

• Storage temperature range: –40°C to +45°C

• Store all system elements in a clean, dry place.

Test Equipment

• 2500 Vdc insulation resistance tester (min.

500 Vdc)

• Ohmmeter

LAYOUT CONSIDERATIONS

Area to be heated

Determine the exact area to be heated, e.g. wheel

tracks. Consider the following factors:

Heat at least one

metre into the

covered area.

nVent.com | 9

Cold lead

Conductor

Ohmmeter

First make sure that the area to be heated

complies with the data in the design instructions.

Establish where the junction boxes are to be

installed and check that the connection leads are

long enough.

The length is 4 m. Thoroughly clean the

substratum before starting to install the heating

mat, as sharp objects can damage the heating

cable.

The EM2-CM-Mat must not be shortened or spliced.

PREPARING SUBSURFACE

The heating mat should be installed on a

stable subsurface. In suspended structures

the substratum may consist of finished slabs,

prestressed concrete or a suspended structure

with poured concrete.The heating mat can be laid

on all subsurfaces.

In the case of poured concrete, it should be

ensured that the surface is smooth and all

sharp objects are removed. Ramps on a solid

substratum do not require any additional thermal

insulation.

Appropriate preparations should be made for

installing the temperature and moisture sensor.

CABLE RESISTANCE AND INSULATION RESISTANCE TEST

Testing the heating mat involves the measuring

of the conductor resistance and the cable

electrical insulation resistance.

The conductor resistance is measured with

an ohmmeter. A deviation of up to 10% from

the nominal resistance is permissible. See table

on page 5.

10 | nVent.com

The insulation resistance should be measured with the aid of a 2500 Vdc

(500 Vdc minimum) insulation resistance tester. The reading should be 100Mohms min.

Record all the measured values on the Installation Test Record provided.

HEATING MAT INSTALLATION

All connections and electrical testing should be carried out by a qualified electrician.

The heating mats should be installed for ramp and driveway heating.

For irregular shaped areas, it is acceptable to cut the tape of the mat (not the heating cable) in order to

cover the entire area.

However, the heating cable within the mat should:

• not be cut or damaged,

• not be crossed over

• not be installed within 10 cm of another section of heater,

• not be installed across expansion joints or separate concrete slabs.

Minimum cable spacing is 10 cm

The heating mats must be secured to the underlaying surface to prevent movement during the

installation.

The cold lead cable should be protected in a conduit. The entire length of heating cable should be

covered by wet sand-cement mixture, screed, or dry sand depending on the selected top surface.

DRAIN TRACING SYSTEM WITH SELF-REGULATING HEATING CABLE

GM-2XT

Purpose

The drain tracing system ensures that melt water

can drain away.

Note: the drain tracing circuit should be

controlled by the same control system as the

other heating circuits.

Install Junction box (10)

Choose a position:

• close to the drain

• indoors if possible.

Install Connection Kit (11)

Terminate the GM-2XT heating cable into the

junction box in accordance with the instructions

provided with the Connection Kit.

Lay out the Heating cable (12)

Protect the heating cable with conduit

between the junction box and the drain. Trace

the entire length of the drain to ensure that melt

water will always have a drain-off path.

Install the End Seal (13)

Install the end seal following the instructions

provided with the End Seal kit.

Perform an Insulation Resistance Test

The insulation resistance test detects damage to

the heating cable such as

cuts or punctures. It should be carried out

using a 2500 Vdc instrument. Lower voltage

instruments are less sensitive and are not

recommended. The instrument should have a

test voltage of not less than 500 Vdc.

Proceed as follows:

• Connect one lead to the heat strip braid.

• Connect the other lead to both heat strip

conductors together.

• Apply voltage. The resistance reading must be

greater than 100 MΩ.

• If the insulation resistance is less than this,

the heat strip is damaged. Where possible,

locate the fault and rectify. Record the

insulation resistance value on the Installation

Test Record.
