High Power Meter Wiring Connections
The NEMA 4X enclosure contains an integral wiring compartment with one
dual strip terminal block (located in the smaller end of the enclosure). Two
3/4-inch female NPT conduit entries are available for separate power and
signal wiring. For all hazardous area installations, make sure to use an agen-
cy-approved fitting at each conduit entry. If conduit seals are used, they
must be installed within 18 inches (457 mm) of the enclosure.
Figure 2-25. AC Wiring Terminals
Input Power Connections
To access the wiring terminal blocks, locate and loosen the small set
screw which locks the small enclosure cover in place. Unscrew the cover
to expose the terminal block.
AC Power Wiring
The AC power wire size must be 20 to 10 AWG with the wire stripped 1/4
inch (7 mm). The wire insulation temperature must meet or exceed 85°C
(185°F). Connect 100 to 240 VAC (5 W maximum) to the Hot and Neutral
terminals on the terminal block. Connect the ground wire to the safety
ground lug ( ). Torque all connections to 4.43 to 5.31 in-lbs (0.5 to 0.6
Nm). Use a separate conduit entry for signal lines to reduce the possibility of
AC noise interference.
Warning!
To avoid potential electric shock, follow
National Electric Code safety practices or
your local code when wiring this unit to a
power source and to peripheral devices.
Failure to do so could result in injury or
death. All AC power connections must be
in accordance with published CE direc-
tives. All wiring procedures must be per-
formed with the power off.
Caution!
The AC wire insulation temperature rating
must meet or exceed 85°C (185°F).
