Mounting
The PD6830 has two slotted mounting flanges that may be used for pipe mounting or
wall mounting. Alternatively, the unit may be supported by the conduit using the
conduit holes provided.
Refer to Mounting Dimensions, page 52 for details.
WARNING
Do not attempt to loosen or remove flange bolts while the meter is
in service.
Cover Jam Screw
The cover jam screw should be properly installed once the meter has been wired and
tested in a safe environment. The cover jam screw is intended to prevent the removal
of the meter cover in a flameproof environment without the use of tools. Using a M2
hex wrench, turn the screw clockwise until the screw contacts the meter. 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.
Connections
WARNINGS
 Static electricity can damage sensitive components.
 Observe safe handling precautions for static-sensitive components.
 Use proper grounding procedures/codes.
 If the meter is installed in a high voltage environment and a fault or
installation error occurs, high voltage may be present on any lead or
terminal.
To access the connectors, loosen the cover jam screw (if tightened) with an M2 hex
wrench, remove the enclosure cover and unscrew the two captive screws that fasten
the display module into the enclosure. Disconnect the ribbon cable and remove the
display module. Power and signal connections are made to a barrier terminal
connector in the base of the enclosure. Grounding connections are made to the two
ground screws provided on the base – one internal and one external. Use proper
grounding techniques for explosion-proof areas and observe all local and national
electric codes.
