Connecting an external fan motor
Procedure
1. Connect the external fan motor as shown on the terminal diagram pasted into the terminal
box. Comply with the rating plate data and follow the operating instructions.
2. The direction of rotation of the external fan must match the arrow indicating the direction
of rotation. The fan impeller is visible through the air inlet point in the fan cowl on the motor.
If the direction of rotation is incorrect, change it by swapping over two of the phase
conductors in the terminal box of the fan motor.
3. A protective circuit must be provided for electric machines with an external fan to ensure
that the main machine cannot be switched on when the fan unit is not in operation.

Connecting temperature monitoring for the stator winding
The stator winding is monitored for thermal loading by resistance thermometers embedded in
the stator winding.
The connecting leads of the temperature sensors are routed to the terminal box. The switching
and assignment of the terminals is shown on the terminal diagram in the auxiliary terminal box.
WARNING
Hazard due to electric shock
The installation of the temperature sensors for the winding monitoring with respect to the
winding is implemented according to the requirements for basic insulation. The temperature
sensor connections are located in terminal boxes, safe to touch, and have no protective
separation. This is the reason that in the case of a fault, a hazardous voltage can be present
at the measuring sensor cable. When touched, this can result in death, severe bodily injury
and material damage.
When connecting the temperature sensor to external temperature monitoring devices, when
required, apply additional measures to fully comply with the requirement "Hazard due to
electric shock," see IEC 60664-1 or IEC 61800-5-1.
