WARNING
After electrical on-field installation, please make sure all removal of the cover assembly is
done in total observance of the applicable safety rules. All the accessories (cable glands
in particular) must be certified according to the requirements of the installation area and
the relevant applicable regulations. Setting must be done while the actuator is powered
on. As a consequence, all setting operations must be carried out by specifically qualified
personnel for operations on powered electronic cards.

Plant Requirements
Protection devices (over-current breakers, magneto-thermal switches or fuses) must be
provided by the customer to protect the main lines in case of motor over-current or loss of
insulation between phases and earth.
NOTE
The following circuit breakers were identified on the basis of the actuator technical features:
—
Reference: IEC EN 60947-2
—
Characteristic: K
It is the plant engineer’s or installer’s responsibility to select the most appropriate
electric protection.
NOTE
For actuators certified according to CSA standards the field connections shall be done
with certified crimp-on ring terminals.
