Instruction manual

Bad example

The electrical connection between the ECG and the luminaire is poor.

Unnecessary crossovers have been created leading to poorer and

therefore higher resistance connection with earth. This arrangement is also

poor from a thermal point of view.

arrangement for 2-

lamp luminaires

3.2.2.8 Luminaires with

reflector and/or

specular louvres

These parts must be made of metal or at least have a surface (i.e.

anodized) with excellent electrical conductivity.

a) The reflector acts as an effective shield

Provided the reflector has a very good connection to the central

earthing point, the lamp is effectively shielded and there can be no

interaction with the ECG and the wiring. Electromagnetic fields are also

effectively shielded.

The reflector should be connected by a short cable or screw

connection to the body. A poor contact or a loss of contact at this

point would have an adverse effect on the EMC behaviour of the

complete luminaire and could also impair starting.
