Installation
Section 3: Installation
Important points to note:
• Do not damage the explosion-proof mating surfaces on the housing and on the
electrical covers.
• Reinstall all the screws associated with the dismantled parts, and coat them with
a thread sealant after coating them with a lm of copper- or molybdenum-based
grease. This will prevent the screws from sticking and facilitate their removal when
maintenance is required.
• Check that the bolts and screws are of the same dimensions and at least equal
quality to those originally installed (as stated on the nameplate).
DANGER
Do not electrically operate the actuator when the electrical covers are removed. Do not
open the actuator covers when an explosive atmosphere may be present. Ignoring the
above precautions may result in personal injury or death.
• Replace any weather-proof seals that may have been removed (O-ring for the
covers, O-ring for the explosion-proof joint of the motor).
