Brodie BERT-E, Installation And Operation Manual

Page: 11 / 94

Mounting
The BERT-E 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 82 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 ¼ to ½ turn to secure the cover. Caution: Excess torque
may damage the threads and/or wrench.

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.
