8.8. Connecting the power supply
Provide electrical protection devices (circuit breaker,
differential) upstream of the power supply cable to the
ventilation unit. The characteristics necessary for the
dimensioning of the power supply (cable cross-section,
protections, etc.) are listed in chapter I.3 Electrical
characteristics).
Drill through the rubber grommet (A) or (B) positioned on
one side and feed the power cable through it.
One of the grommets (B) is reserved for the drainage of
condensate by gravity system.
Connect the power wires directly to the terminal block of
the isolating switch (marks 1 and 3).
Connect the earth wire (PE) to the crimped nut terminal
near the switch (use an M6 eyebolt).
The protective earth (PE) conductor should be slightly
longer than the phase and neutral wires.
Securely attach and clamp the power cable to an external
fixed part (frame, cable tray, etc.).
