4.3 Connection in terminal box

4.3.1 Preparing cables for connection
Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.
NOTE
Tightness and strain relief are dependent on the cable
used.
→ This must be checked by the user.

4.3.2 Connecting wires to terminals

; Remove the cap from the cable gland.
Only remove caps where cables are fed in.
; Route the wire(s) (not included in scope of delivery) into the terminal
box.
; First connect the "PE" (protective earth).
; Connect the wires to the corresponding terminals.
; Connect the thermal overload protector (TOP).
Use a screwdriver to do so.
When connecting, ensure that no wire ends fan out.
; Seal the terminal box.

4.3.3 Cable routing

Water must be prevented from reaching the cable gland along the cable.
Fans installed lying flat
Make sure the cable is routed in a U-shaped loop.

Operating instructions
Fans installed upright
When routing the cable, make sure that the cable glands are located at
the bottom. The cables must always be routed downward.

4.3.4 Motor protection
The motors are equipped with thermal overload protectors to protect the
devices.
Check to make sure that the thermal overload protector is correctly
connected before each operation.
Failure to connect the thermal overload protector correctly will
invalidate your warranty claim.
CAUTION
Voltage
The device is a built-in component and has no disconnecting
switch.
→ Connect the device to a suitable tripping unit.
→ Only connect the device to circuits that can be switched
off with an all-pole disconnection switch.
→ When working on the device, secure the system/
machine in which the device is installed so as to prevent it
from being switched back on.
NOTE
Lack of motor protection
Without motor protection, the motor can overheat and suffer
damage.
→ Connect the thermal overload protector installed in the
winding.
