Instruction manual

„Hot wires“ are marked on the unit with the shorter cable length. For

reasons of radio interference suppression and reliable starting, the “hot

wires” must be kept as short as possible. In other words, you should install

the ECG to one side in the luminaire, making the low-potential cables

longer so that the length of the high-potential cables can be reduced. This

type of installation is to be preferred to symmetrical mounting.

In luminaires equipped with more than one ECG (systems with 3, 4 or more

lamps), the ECG and its associated lamp(s) should be assigned to one

another. For reasons of radio interference suppression and reliable starting

we do not recommend splitting the luminaire into a lamp and ECG part.

…HE fluorecent

lamps have been optimally designed to comply with just that

recommendation.

For reasons given above we also advise against splitting the ECG into

units located in the luminaire and units located outside the luminaire (e.g.

on the back of the luminaire) if this means much longer cables between the

ECG and the lamps.

3.5 Switching between

Lamp and ECG

In some special applications it may be necessary to disconnect or switch

the cables between the ECG and the lamp(s).

If changeover units are used (emergency lighting modules with internal

switching) which supply the lamp directly from an emergency supply and

interrupt the system circuit between the ECG and the lamp, the following

must be observed:

• Changeover or disconnection of the lamps from the ECG to the

external unit must be on all terminals.

• When switching back from the external supply to ECG operation,

the lamp(s) must first be connected at all terminals to the ECG

before the ECG is supplied with power again, otherwise the cutout

in the ECG will operate.

• Many of these emergency lighting units available on the market do

not comply with the normal operating conditions of the lamp and will

therefore damage it. In such cases, OSRAM cannot guarantee that

the lamp will last as long as indicated.

units are given in Section 6.5.2ff.

3.6 Master-Slave Circuit

An additional single-lamp „slave luminaire“ can be supplied from a two-

lamp ECG installed in a single-lamp „master luminaire“.

This requires a 4-core connecting cable between the two luminaries and, in

general, different cable lengths between the ECG and the lamp in the
