Disconnect the damper from the power supply (electric mains) prior to any work on the unit.
Power mains connection shall only be performed by a qualified electrician. The nominal electrical
parameters of the fan are given on the manufacturer's label. Any tampering with the internal
connections is prohibited and will void the warranty.
The fans take
220-240
V 50/60 Hz single-phase alternating current.
The fan connections (cables and wires) must be durable, insulated and heat-resistant.
The external lead-in
(2
2
0
-240
V 50/60 Hz) must be equipped with a
switch
built into the stationary wiring to disconnect all the
mains phases. The location of the
S
external switch must ensure unobstructed access for shutting down
the fan quickly if required.
The conductor cross-section values are given for reference only while the actual selection must be based
on the maximum permissible wire heating which depends on the wire type, its insulation, length and
installation method (i.e. overhead, in pipes or inside the walls).
The recommended current of the switch is the next current in the standard current row following the
maximum current of the connected unit. The switch is not included in the delivery set.
