OSRAM POWERTRONIC PT-FIT I ECG for HID lamps, with cable clamp - Manual (Page 14)

THE PRODUCT IN OPERATION
2.2.4.4. Cable layout
In order to achieve good radio interference suppression
and the greatest possible degree of operational safety,
attention should be paid to the following points for wiring:
1. Keep the cable between ECG and lamp as short as
possible.
2. In order to prevent coupling of lamp lines with mains
lines, avoid laying them parallel to each other. The dis-
tance between such cabling should be at least 5 cm.
Where a crossover is unavoidable, it must be done at
right angles.
3. Where it is impossible to avoid laying longer lamp
cabling, the two strands (LH and LL) must be twisted.
4. Keep mains cables inside the luminaire short and as
far away as possible from the ECG.
5. Very short low-inductive connection of the protective
earth to the ECG and to all metallic parts of the lumi-
naire (e.g. its refl ector).
6. For luminaires that do not conform to EMC limits it may
be necessary to add a ferrite to both lamp cables. The
impedance of the ferrite will depend on the wattage of
the device and the luminaire. The higher the wattage,
the larger impedance you will need to select. The impe-
dance can be varied by changing the number of twists.
Typical ferrite values: 20–70 W → 250 Ω;
100 W–150 W → 400 Ω
7. Unprotected cable transition through metal parts should
never be used. They should always be made using ad-
ditional insulation (insulation tubing, cable-entry grom-
met, edge protection, etc.).
During wiring you should observe the rules set out in the
EN 60598-1 standard for luminaires, and also any country-
specifi c regulations in their version currently in force.
The luminaire housing or any part of it must never be
"abused" as a conductor or in any other way have contact
with the mains or lamp conductors (e.g. via bare wires,
excessively long stripping lengths, screws projecting from
the insulation or by excessively sharp edges on sheet
metal). Any such contact is dangerous for people and can
lead to the destruction of the control gear.
Question: Are L and N swappable (e.g. for portable
luminaires)?
Yes
on labeling on the casing ~
Yes on labeling on the casing L, N
(applies to Class II luminaires only)
No on labeling on the casing L, N
(applies to Class I portable luminaires)
