6. ELECTRICAL INSTALLATION
Only qualified professionals may perform electrical installation works in accordance with the manufacturer’s instructions
and applicable legal acts and safety requirements. Before installation of any electrical components:
•
Make sure the unit is unplugged from the mains.
•
If the unit has been standing in an unheated room for a long time, make sure there is no con-
densation inside and check if contacts and electronic parts of the connectors are not damaged
by moisture.
•
Inspect the power cable ant other wiring for damage in insulation.
•
Locate the wiring diagram for your unit according to the unit type.
6.1. Requirements for Electrical Connection
•
Connect the unit only to a proper power outlet with protective earthing. Earthing must be in-
stalled according to the EN61557, BS 7671 requirements.
•
It is recommended to connect AHU to the mains via automatic circuit breaker with 300 mA cur-
rent leakage protection (type B or B+).
•
Control cables should be installed at least 20 cm away from power cables to reduce the possibil-
ity of electrical interference.
•
All external electrical elements must be connected strictly according to the wiring diagram of
the unit.
•
Do not disconnect the connectors by pulling wires or cables.
Lead-in cable diameter depends on a maximum current specified in the technical data print-out of the specific unit.
