Important Information

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 6591U-101-500/6594U-500 are installed in a
flush-type box according to DIN 49073-1.
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%. Depending on the application, the
dimmers 6591U-101-500/ 6594U-500 can be connected in
accordance with the connection diagrams Fig. 1 to
Fig. 3.
