OPERATION

6.1

Electrical Connections and Preliminary Test


For testing purposes, loosen the bolts of the actuator cover and remove the cover.

Make sure that the power supply voltage is in accordance with the information on the
nameplate of the actuator.

Cables shall be passed through the cable glands: M25 or NPT ¾" for "Ex db" versions. M25, M20
and NPT ¾" with M30 adapter shall only be applied for "Ex tb" versions.

Connect wires according to the enclosed wiring diagram (See Appendix I)

Manually move the valve to the half-open position. Then electrically operate the actuator to
the fully open position and check if the motor rotates in the correct direction. According to the
applicable standards, the actuator must be closing in counter-clockwise direction.

Test the actuator and check whether the limit switches work correctly

After testing, check if all cable glands are correctly tightened. Applicable cable glands must be
selected to meet the application's condition. It is recommended to use at least IP67 cable glands.

Put the cover back on the actuator and tighten the bolts.

Note: For more information, refer to Appendix II

WARNING:
If working in potentially explosive areas, observe the European
Standards EN 60079-14 "Electrical Installation in Hazardous Areas" and
EN 60079-17 "Inspection and Maintenance of Electrical Installations in
Hazardous Areas". Work on the electrical system or equipment must
only be carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of such an
electrician and in accordance with the applicable electrical engineering
rules.
For cable gland or conduit entries that are not used, user or installer
shall close those entries by certified blanking elements in order to
maintain the enclosure protection. Extra attention is required for
selecting the correct "Ex db IIC" or "Ex tb IIC" blanking elements.
For cleaning a dust ignition proof closure, a damp cloth shall be used.
An explosion proof enclosure must be treated with care. Seals and
sealing surfaces may not be damaged in any way. Do not jam during
assembly.
Dust ignition proof enclosures may not be charged with an electrostatic
load. It therefor shall be installed in such a way, that the risk from
electrostatic discharge and propagation brush discharge, caused by
rapid flow of dust, is avoided.
DANGER:
HAZARDOUS VOLTAGE. Electrical power must not be connected
until all wiring and
completed. Once
precautions must be taken if the cover is not mounted.
