Do not open actuator cover if there is risk of an
explosive environment. Care must be taken with the
joint surface when handling, installing or storing to
preserve the integrity of the explosion-proof joint. See
joint handling instructions under the Installation section
of this manual. Failure to observe these instructions may
compromise the enclosure protection rating.
Fasteners
Both Metric and Imperial fasteners used, use applicable
tools. The enclosure cover bolts and the hard stop
assembly are metric threads and the rest of the others are
imperial threads.
All fasteners must be intact and properly tightened.
Enclosure cover screws, mounting fasteners and cable
glands must be tightened to specified torque values.
Failure to maintain specified torque for cover screws and
cable glands may compromise the enclosure protection
rating. Failure to maintain specified torque for mounting
fasteners may compromise actuator operation. See
Installation and Maintenance sections of this manual
for specified fastener and torque requirements, as
well as safety and maintenance information.
Seals
All seals must be routinely checked to ensure that
they are in good condition, properly sealed and
replaced as needed. Failure to do so may compromise
the enclosure protection rating. See Installation and
Maintenance sections for instructions.
