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 15.8 inch (400 mm) and 23.6 inch (600 mm) cabinets.
Two 100 W heaters (-E240, -E241) are used for cabinet widths of 31.5 inch (800 mm) or
higher.
The supply voltage (110 to 230 V AC) must be provided externally and protected with a fuse
with max. 16 A.
