Description
The cabinet anti-condensation heating can be used at low ambient temperatures and high
levels of humidity to prevent the formation of condensation.
A 100 W heater (-E240) is used for 400 mm and 600 mm cabinets. Two 100 W heaters (-
E240, -E241) are used for cabinet widths of 800 mm or higher.
The power supply (110 to 230 V AC) must be provided externally and protected with a fuse
of up to 10 A.

cabinets even when the main breakers in all units are open.
You must observe the "five safety rules" when carrying out maintenance work.
