AEL7 Series Electric actuator
4.1 Electrical Connection Safety Information
Caution
Before commencement of any work to make the electrical please read to Section 1 "Safety
Information".
Warning
Mains connection and commissioning of the AEL7 Series actuator requires specialist
knowledge of electrical circuits and systems, and the inherent dangers. A working knowledge
of linear actuators is also required.
The operator is responsible for ensuring that safe systems of operation and practice are
implemented and maintained. Only qualified personnel must be allowed to make the electrical
power connections to the AEL7 Series actuator, and these personnel must be familiar with,
and comply with the applicable health and safety standards or guidelines. Failure to do so
could result in death, severe physical injuries or material damages to the actuator, valve
and associated equipment.
-
Ensure that the electrical power supply is isolated
-
Safeguard against the unintentional switching on by ensuring that there is a safe system
of practice in operation – e.g. lock the electrical supply isolator
-
Ensure that any installation of any new power supply is compliant with local regulations
-
Check the mains connection voltage and frequency for conformity to the actuator. Details
of the requirements are identified on the AEL7 Series actuator nameplate which can
be found on the actuator baseplate
-
Ensure that the power supply cable is of the correct cross section for the maximum
expected load. Details of the requirements are identified on the AEL7 Series actuator
nameplate which can be found on the actuator baseplate, and in the Technical
Information Sheet (TI-P713-02)
-
Minimum cross section for the power supply cable is 1 mm
2
. Conductors below this
area can result in operational disturbances (please note maximum cable core size
1.5 mm
2
for 1.2 kN actuators - larger cable cores can prevent the cover from seating
correctly)
-
Ensure that the power supply is correctly fused for the maximum expected load. Details
of the requirements for each AEL7 Series actuator can be found in Tables 6 to 9
