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
To access the connectors, remove the enclosure cover and unscrew the two
captive stainless steel screws. Remove the meter assembly from the enclosure.
Signal connections are made to a three-terminal removable connector on the
back of the meter assembly. Grounding connections are made to the two ground
screws provided on the base – one internal and one external.
WARNING:
Do not attempt to loosen or remove flange bolts while the meter
is in service.
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.
