3.1.4 Insulation

Depending on the type of terminal the length of insulation to be stripped

from the ends of the cables is different. The exact value can be found on

the ECG.

3.1.6 Cable routing

To ensure good radio interference suppression as well as maximum safety

and reliability, the following rules for cable routing should be observed:

1.) Cables between ECG and lamp (HF cables) should be

kept as short as possible to reduce electromagnetic

interference. Please pay attention to the maximum

recommended cable lengths as indicated on the ECG

(see also overview in 7.1ff)

2.) Mains and lamp cables should never be routed in

parallel. Keep HF cables and mains cables as far away

from one another as possible (e.g. 5 to 10 cm). This

avoids mutual interference between mains and lamp

cables.

3.) Lay HF cables away from earthed metal surfaces (if

possible several cm away) to reduce capacitive

interference.

4.) If long HF cables are unavoidable (e.g. in master-slave

circuits) they should be twisted together.

5.) Keep mains cabled in the luminaire as short as possible

to reduce interference.

6.) Do not lay mains cables too close to the ECG or the

lamps. This applies in particular to through-wiring.

7.) Avoid crossing mains cables and lamp cables; if this is

not possible, they should cross at right angles to reduce

mains and HF interference.

8.) Lamp cables at high potential (see section 7.1ff „Hot

wires“) must be kept as short as possible, particularly

with luminaires for tubular fluorescent lamps such as

…HE and FQ

…HO.
