INSTALLATION AND MAINTENANCE TIPS
WARNING:
If working in potentially explosive areas, be sure to comply with the
standard EN 60079-14
“
Electrical Installation in Hazardous Areas
”
Work on an actuator with an open cover and which is under voltage,
may only be performed if there is no explosion danger for the duration
of the work.
In case of an explosion proof enclosure, the actuator may only be
opened in the absence of flammable gas, dust and voltage.
During operation, installation and maintenance, treat cover with care.
Seals and sealing surfaces may not be pinched, damaged or dirty in
any way. Damaged seals (O-rings) must be replaced.
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.
CAUTION:
Regular inspection and maintenance should be performed by
qualified and trained personnel
If working in potentially explosive areas, be sure to comply with the

.
Working on the actuator that is in open position and under voltage
must only be performed if it is assured that there is no danger of
explosion for the duration of the work.
Pay attention to national regulations
For any installation and maintenance work, the followings should be noted:
•
Check the actuator visually. Ensure that no external damage or changes are visible. The
electrical cables must not be damaged and wired correctly.
•
Cable entries, cable glands, plugs, etc. have to be checked whether they are correctly
tightened and sealed.
•
Check if the Ex-connections are correctly fastened.
•
Check for possible discoloration of the terminal strip and wires as this may indicate an
increased temperature.
•
Check the flame path seals of the explosion proof enclosures for any dirt and corrosion. Since
the dimensions of all Ex seals are strictly defined and inspected, no mechanical work shall be
performed on them.
•
All cables and motor protection elements have to be checked.
•
If any defects are detected during maintenance that may affect the safety, repair measures have
to be taken immediately.
•
Any kind of coating for sealing surfaces is not permitted.
•
When replacing parts, seals, etc., only original spare ones must be used.
