Cabinet anti-condensation heating (option L55)

Description
The anti-condensation heating is used at low ambient temperatures and high levels of
humidity to prevent condensation forming.
One 100 W heater is installed for a 400 mm and 600 mm cabinet panel, and two 100 W
heaters for an 800/1000 and 1200 mm cabinet panel. The power supply for the heating (110
V – 230 V AC) must be provided externally and fused at max. 16 A.
When the supply voltage for the cabinet anti-condensation heating is connected, dangerous
voltages are present in the cabinet unit even when the main circuit breaker is open.
