8. Electrical connection
8.1 Safety instructions
The electrical connection of this product requires expertise in electrical engi-
neering. This knowledge, generally learned in professional training in one
of the fields stated, is not described separately here. Connection errors can
result in damage to the unit! The manufacturer is not liable for any damage
to people and materials caused by incorrect connection and / or improper
handling! Note the following safety instructions before starting work on the
controller and the ProtecTor:
• Regularly check the ProtecTor's electrical equipment. Immediately replace
loose connections and faulty cables.
• Disconnect the system and ensure that it cannot be accidentally recon-
nected.
• Wire the electrical connection in accordance with the enclosed
wiring diagrams.
• Only connect the unit in accordance with currently applicable VDE and
EN guidelines, as well as Technical Wiring Regulations stipulated by the
regional energy supply companies.
• Only connect the unit to permanently installed lines.
• The operator of the unit is responsible for ensuring EMC compliance of
the entire system in accordance with the locally applicable standards.

Electrical loading (>50 °C) between the mains conductor and protective
conductor after switching off the mains power supply when switching sev-
eral fans in parallel.
• Ensure that an adequate contact safety device is fitted. The mains con-
nections and PE need to be shorted before working on the electrics.
The terminals and connectors are still energised even when the unit is
switched off. Check whether the terminals and connectors are de-energised
with a two-pin voltage tester.
• Only open the unit 5 minutes after all poles of the voltage have been
switched off.
The PE conductor carries high leakage currents (depending on the frequen-
cy, intermediate voltage and motor capacity). Therefore check EN-compliant
earthing under test conditions (EN 50 178, art. 5.2.11). Hazardous voltage
can occur at the motor housing without earthing.
