4.3.2 Motor protection
CAUTION
Voltage
The device is a built-in component with no isolating switch.
→ Connect the device to a suitable tripping device.
→ Only connect the device to circuits which can be de-
energised with an all-pole disconnection switch.
→ When working on the device, the system/machine in
which the device is installed must be secured 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 up the thermal overload protector installed in the coil.
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 up the thermal overload protector correctly will
invalidate your warranty claim.
