•
The chain/rope may not touch the impeller and the possibly mounted frequency
inverter when lifting with the lifting beam, otherwise damage is possible.
•
At a weight greater than 25 kg for men / 10 kg for women, the fan should be lifted out
of the package by two persons (according to REFA). The values may differ from
country to country.
4.3 Connection lead & terminal box
Be aware of the following Points:
•
In demanding environments (wet rooms, outdoor installation), connecting cables must
have water draining pipe elbows.
•
If using a terminal box, install this lower than the motor to ensure that water cannot
penetrate through to the controller housing from the connecting cables.
•
Fasten the motor connection cable with cable tie to the motor suspension or guide it
directly through the housing and fasten to the motor suspension as required.
4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to
operate the motor/fan for at least two hours every month at 80 - 100 % of maximum
speed to remove any moisture that has penetrated inside.
If available, the stationary heaters must be turned on when the motor is not running.
