Electrical connection
Safety information
♦
Observe 2
♦
Prevent the ingress of water into the connection box.
Connection
♦
Check if the data on the nameplate matches the
connection data.
♦
Complete the electrical connection according to the
circuit diagram.
♦
Fans with EC- motors must be switched on/off via the
control input.
♦
Connect the cable end in a dry environment.
♦
Install a circuit breaker in the permanent electrical
installation, with a contact opening of at least 3 mm
at each pole.
Protective grounding wire
The protective grounding must have a cross-section equal to or greater than that of the phase conductor.
Residual current circuit breaker
All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60
Hz, in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies
(UPS).
