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 a 400 mm and 600 mm cabinet. Two 100 W heaters
(-E240, -E241) are used for cabinet widths of 800 mm or greater.
The power supply (110 to 230 V AC) must be provided externally and protected with a fuse
of up to 10 A.
