Note:
Depending on the configuration ordered, there is a pre-
fitted WIELAND plug (male) with brown/red coding in the
LED KIT and in the “PROFESSIONAL” / “PROFESSIONAL
HP” version, this is assigned with (L I PSt I N). With many
standard luminaires (usually in the SKI version), a device
socket from ADELS with white coding or a device socket
from WIELAND with black coding is fitted on the feeder
and attached to the central protective conductor connec-
tion. If no control line exists or is to be used on the mast
side, this white/black socket (female) can be combined
with the brown/red plug on the LED KIT provided that the
PSt conductor is disconnected from the plug on the LED
KIT side. This should be clearly marked on the WIELAND
plug for inspections at a later date. Alternatively, a
WIELAND socket with red/brown coding can be ordered
as an accessory and fitted on the feeder in place of the
white socket, in which case the protective conductor
must not be attached!
The PSt control input of the LED
KIT must never be connected with the protective con-
ductor.
In the “Basic” version, the central contact of the WIELAND
plug, which may be fitted on the LED KIT, is not assigned.
In this case, the feeder’s socket can be connected just
as it is.
