Electrical connection

Observe the applicable regulations for electrical installations, e.g. DIN EN 50110-1 and DIN EN 60204-1, in Germany in particular VDE 0100 with the corresponding parts.

DANGER due to electric shock

Observe the safety rules of electrical engineering. Before taking off covers and before installing the electrics, shut down all supply circuits, switch off mains fuse, check that no voltage is present, secure against being accidentally switched back on and position a visible warning sign.

DANGER Risk of short circuit/fire if moisture penetrates the electronics compartment. Short circuits and fire can lead to serious injuries with fatal consequences.

Ensure correct, tight cable feed through the cable glands and long-hole diaphragm grommet.

CAUTION Risk of injury due to sharp edges on sheet metal/break-outs in the housing or in the electronics compartment.

Wear protective gloves. Carefully guide connecting cables into unit. Do not damage cables.

If the connecting cables are too short, the electronics unit cannot be fully pulled out and fitted on the housing. Ensure connection cables of a sufficient length inside the ventilation unit.

A fixed wiring for the mains connection is mandatory. The power cable is already wired inside the unit and led out of the unit.

Take electronics unit (with A1 main board) out of ventilation unit and attach as described below.

  1. Switch the mains fuse off.
  2. Remove the front cover → WS 160 Flat: Front cover installation aid set or WS 300 Flat: Front cover installation aid set.
