Installation
CAUTION
Work on the 230 V supply system may only be carried
out by authorised electricians! The line-side fuse is to
be disconnected when working on the lighting unit.
The dimmers 6593/6594-102-500 for distribution systems
are mounted on a standard 35 mm rail.
When several dimmers are operated in one distribution
system, a packing (Art. No.: 3099-0-0272) should be in-
stalled between two dimmers.
Universal Master Dimmers and power modules heat up
when in operation due to the fact that a portion of the
installed load is converted, as power dissipation, into heat.
Should the ambient temperature increase during operation
to over 35 °C, the installed load must be reduced in
accordance with the diagram (Fig. 4).
With an ambient temperature of 50 °C, the permissible
power output drops to 57%; with 60 °C, to 28%.
