WIRING
3.1 PREPARING CONDUIT OPENINGS
The number of conduit openings and the location depend on the model.
Conduit openings accept 1/2-inch conduit fittings or PG 13.5 cable
glands. To keep the case watertight, block unused openings with NEMA
4X or IP65 conduit plugs.
NOTE
Use watertight fittings and hubs that comply with the requirements of
UL514B. Connect the conduit hub to the conduit before attaching the
fitting to the analyzer (UL508-26.16).
Figure 3-1 shows how to remove the knockouts. The knockout grooves are on the outside of the case. Place the
screwdriver blade on the inside of the case and align it approximately along the groove. Rap the screwdriver
sharply with a hammer until the groove cracks. Move the screwdriver to an uncracked portion of the groove and
continue the process until the knockout falls out. Use a small knife blade to remove the flash from the inside of the
hole.

The Solu Comp II is available in two mounting configurations. The positions of the power, alarm, output, and sen-
sor terminals are different in each. Refer to the table below to find the correct drawing.

AC connections and grounding must be
in compliance with UL 508 or local elec-
trical code. DO NOT apply power to the
analyzer until all electrical connections
are verified and secure.
WARNING:
RISK OF ELECTRICAL SHOCK
For best EMI/RFI protection use shielded output signal cable
enclosed in an earth-grounded metal conduit. Connect the shield
to earth ground at terminal 4 on TB1.
AC wiring should be 14 gauge or greater. Provide a switch or
breaker to disconnect the analyzer from the main power supply.
Install the switch or breaker near the analyzer and label it as the
disconnecting device for the analyzer.
Keep sensor and output signal wiring separated from power
wiring. Do not run sensor and power wiring in the same conduit or
close together in a cable tray.
