If the actuator is handled improperly or not used as specified, the resultant may:
-
cause danger of the life and limb of the third party,
-
damage the actuator and other assets belonging to the owner,
-
hinder the performance of the actuator.
1.1 Wiring notes
Every effort has been made during the design of the actuator to ensure the safety of the user, but
the following precautions must be followed:
i)
Maintenance personnel must be suitably qualified in working with equipment containing
hazardous live voltages.
ii)
Ensure correct installation. Safety may be compromised if the installation of the product is
not carried out as specified in this manual.
iii)
Isolate the actuator from the mains supply before opening the unit.
iv)
The actuator is designed as an installation category II product, and is reliant on the building
installation for overcurrent protection and primary isolation.
v)
Wiring should be carried out in accordance with IEC 60364 or equivalent.
vi)
Fuses should not be fitted in the protective earth conductor. The integrity of the installation
protective earth system must not be compromised by the disconnection or removal of other
equipment.
vii)
A disconnecting device (switch or circuit breaker) must be included in the building installation.
This must be in close proximity to the equipment and within easy reach of the operator.
-
There must be a 3 mm contact separation in all poles.
-
It must be marked as the disconnecting device for the actuator.
-
It must not interrupt the protective earth conductor.
-
It must not be incorporated into a mains supply cord.
-
The requirements for the disconnecting device are specified in EN 60947-1 and EN 60947-
