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 flame-
proof environment without the use of tools. Using a
M2 hex wrench, turn the screw clockwise until the
screw contacts the enclosure’s base. Turn the screw
an additional 1/4 to 1/2 turn to secure the cover.
•
Excess torque may damage the threads, screw
head, and/or wrench.
