Cabinet anti-condensation heating for the power unit (option L55)

The anti-condensation heating is used at low ambient temperatures and high levels of humidity
to prevent condensation from forming. The heating is controlled via a thermostat. The heating
is supplied with voltage externally (110-250 V AC/VDC) and must be fused with 10 A.

(option L58)
Each cabinet is equipped with a heater with a thermostat and hygrostat. The heater is supplied
with voltage (110-250 VAC/VDC) via the infeed provided by the customer.
3.5.12

Dust protection (option M11)

To prevent dangerous dust deposits from accumulating in the power unit components,
additional filter mats are attached to the outside of the device.
A differential pressure technique continually determines the amount of dust in the filter mats.
When the differential pressure switch responds, a fault message is output and the converter
is switched off.
