Protection against humidity
Protect the external fan against moisture. Water must not be allowed to run along the cables
and into the terminal box of the external fan.
● Use suitable cables at the connection cable gland on the terminal box.
● Attach the terminal box cover of the external fan orrectly and completely.
WARNING
Voltages at the internal motor connections
The motor may continue running, e.g. due to airflow, or may run on after being shut down.
This means that dangerous voltages of over 50 V can occur at the internal motor connections.
This can result in death, serious injury or material damage.
● For safety reasons, it is not permissible to make any unauthorized modifications or
changes to the fan.
● Wait until the external fan has come to a standstill before approaching it.
● Provide a protective circuit that prevents the main motor from being switched on when the
external fan is not in operation.
– After a power failure or when the power has been disconnected, the external fan starts
up automatically again when the voltage is restored.
– The external fan can automatically switch on and switch off as a result of its inherent
function.
NOTICE
Remove the jumper in the fan terminal box inserted in the factory
If the company operating the plant or system removes the jumper in the fan terminal box
(which was inserted in the factory), then that company becomes responsible for the functional
safety of the drive.
The motor can overheat. This can result in material damage.
● Carefully follow the safety instructions.
