Unpacking
Remove the instrument from packing box. Inspect the packaging and contents for
damage. Report damages, if any, to the carrier.
If any part is missing or the instrument malfunctions, please contact your supplier or
the factory for assistance.
Pre-Installed Conduit/Stopping Plug
The PD8 Series is supplied with two pre-installed conduit plugs for installations that
do not require the use of all conduit entries. The conduit/stopping plugs include an
internal 12mm hexagonal socket recess for removal. The pre-installed plugs and their
installation are included in the hazardous area approvals for the PD8 Series
enclosure.
WARNING
In hazardous areas, conduit and conduit/stopping plugs require the
application of non-setting (solvent free) thread sealant. It is critical
that all relevant hazardous area guidelines be followed for the
installation or replacement of conduit or plugs.
Mounting
The ProtEX-MAX Series has four slotted mounting flanges that should be used for
pipe mounting or wall mounting.
Refer to Mounting Dimensions, page 30 for details.
WARNING
Do not attempt to loosen or remove flange bolts while the
instrument is in service.
Cover Jam Screw
The cover jam screw should be properly installed once the instrument has been wired
and tested in a safe environment. The cover jam screw is intended to prevent the
removal of the instrument cover in a flameproof environment without the use of tools.
Using a M2 hex wrench, turn the screw clockwise until the screw contacts the
aluminum enclosure. Turn the screw an additional 1/4 to 1/2 turn to secure the cover.
Caution: Excess torque may damage the threads and/or wrench.
