The user must ensure that the operating
environment and any materials
surrounding the actuator cannot lead
to a reduction in the safe use of, or the
protection afforded by, the actuator.
Where appropriate the user must
ensure the actuator is suitably protected
against its operating environment.
WARNING:
Operating by Hand.
With respect to optional manual
operation of Rotork SI actuators, refer
to section 6.1.
WARNING:
Actuator may start
and operate when remote is selected.
This will be dependent on remote
control signal status and actuator
configuration.
WARNING: Unit Weight
The actuator weight is shown on the
nameplate. Care must be taken to
transport, move or lift the actuator
safely. Lifting information is available in
section 4.
2.1 Hazardous Area Approved
Actuators
Special Conditions of Safe Use
Refer to the actuator nameplate for
unit specific details.
This equipment shall be installed such
that the risk of impact to the window
is low.
This equipment includes some external
non-metallic parts, including the outer
protective coating. The user shall
therefore ensure that the equipment is
not installed in a location where it may
be subjected to external conditions
(such as high-pressure steam) which
might cause a build-up of electrostatic
charges on non-conducting surfaces.
Additionally, cleaning of the
equipment should be done only with a
damp cloth.
The equipment utilises A4-80 fasteners,
if these are changed they shall only be
replaced by A4-80 fasteners.
The equipment flamepaths require
specialist inspection equipment for
verification and should not be repaired.
Ensure that appropriately certified
threaded adapters, cable glands or
conduit are tight and fully waterproof.
Seal unused cable entries with steel
or brass threaded plugs. In hazardous
areas an appropriate certified threaded
blanking plug must be installed at
the cable entry without the use of an
interposing thread adapter.
Actuators approved for use in Ordinary
and Hazardous Locations in Canada
and the USA require mains supply
cables to comply with CSA C22.2 No
21 or ANSI/UL 817.
SI wiring can reach 81 ºC (178 ºF) in
70 ºC (158 ºF) ambient temperature.
