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.
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.
