4.1 PREPARE ANALYZER CONDUIT OPENINGS

The analyzer enclosure has six conduit openings. Four conduit openings are fitted with conduit plugs.

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).

4.2 PROVIDE POWER TO THE SAMPLE CONDITIONING SYSTEM

WARNING

RISK OF ELECTRICAL SHOCK

Electrical installation must be in accordance with the National Electrical Code (ANSI/NFPA-70) and/or any other applicable national or local code.

NOTE

Provide a switch or breaker to disconnect the sample conditioning cabinet from the main power supply. Install the switch or breaker near the unit and identify if as the disconnecting device for the sample conditioning system.

1.Be sure the pump switches on the wiring access panel are in the off position.

2.Remove the four screws securing the wiring access panel. Pull the panel out of the way to reveal the power terminal strip.
