Ceiling mounting
Extent of supply
•
Cable with special plug
•
Line clamps on the flange
Please take note:
•
Mark the cables with special plugs on both sides with numbers (only combinations): 1=main
light, 2=satellite lamp 1, 3=satellite lamp 2).
•
Mark also the receptacles on the axis (the lowest position with 1, the other positions increas-
ing with 2 and, if present, with 3).
Put the cables with special plug through the flange tube. Ensure that the cables are cut to a length which
allows approx. 15cm cable to extend from the suspension tube.
The flange is fitted with line clamps for connecting the light system to the electrical circuit. These clamps
should be accessible for electrical safety checks during installation and also later.
Connect the mains supply and the cables with special plugs to the line clamp in the right order (plug no.1
to receptacle no.1, etc.).
Wall attachment
The lamp is normally supplied with integrated transformer and connection cable with shock-proof plug
(except Mach 120 and Mach 380). The socket used must be installed according to IEC or VDE 0107 re-
quirements.
The cross-sections of the leads depend on the lead-length and power consumption. Please refer to the
following table:
Lead length [m]
Power consumption
[W]
up to 10
up to 20
up to 40
up to 70
50 2,5 2,5 2,5 4,0
150 2,5 2,5 4,0 6,0
200 2,5 4,0 6,0 10,0
250 2,5 4,0 6,0 10,0

Once the electrical connections have been completed, check that the system functions correctly in a no-
load operation trial run.
When connecting to an external transformer, the emerging voltage U will be approx. 10-20% above rated
voltage because of no load and anticipated lead losses. There is no point in making any adjustments until
the lamps have been completely mounted.
