The meter wires are routed through three ½-inch conduit fittings located on the back of the
meter (see Figure 17). The left conduit hole (as viewed from the front of the meter) is for
alarm connections, the center conduit hole is for power connections and the right conduit
hole is for electrode, recorder, controller, and SIO connections. The left and right conduit
holes have molded-in knockouts, which must be removed if used. To maintain the NEMA
4X and IP66 ratings of the enclosure, the conduit fitting (not supplied) must be a sealing
type. To make the wire connections refer to Section 5.6.1 Wire Preparation. Remove the
front panel of the meter by removing the four corner screws. Disconnect the existing wires
from the front panel by unplugging the connector(s) (see Figure 18 on page 64).
Remove the wire shield. Unplug the connector from the circuit board on the front panel,
and hook up the wires. Replace the wire shield, routing the wires through the notches, and
verifying that the shield wire stays under the wire shield. Plug the connectors into the
circuit board, and replace the front panel of the meter.
