Electrical Wiring Test

The following test procedure will ensure that the Power Ar- ray has been correctly hardwired. The qualified electrician who installed the Power Array should perform this test. A true RMS voltmeter and a ground ohmmeter are required.

Before this test can be conducted, the main intelligence mod- ule (MIM) must be installed, and the PowerView display must be connected to the Power Array. Refer to Chapter 5 for pro- cedures to install the MIM and the PowerView.

IMPORTANT: Make sure the power modules and the battery modules ARE NOT installed for this test.

Note: This test is intended to verify the electrical connection to the Power Array, not to verify its operation or explain its usage. In this procedure, you will be instructed to ignore PowerView messages, etc. Refer to Chapters 6 & 7 for detailed information about the operation of the Power Array.

Electrical Wiring Test/Checklist

q1. Make sure all three switches -- system enable, mainte- nance bypass, and input circuit breaker -- are in the “off” or “stand by” position.

IMPORTANT: Make sure all load equipment is either turned off or is unplugged from the Power Array.

q2. Use a true RMS voltmeter to measure the input AC utility (mains) voltagte to the terminal connections at the rear of the frame (bottom level).

Note: If input voltage is less than 156Vrms or greater than 276Vrms, check input wiring for errors. DO NOT PRO-

CEED UNTIL THE INPUT VOLTAGE IS WITHIN THIS RANGE.

Record the input voltage here: ____________________

q3. Check for proper ground installation with a ground ohmmeter. Check for continuity to building ground.

q4. Switch the input circuit breaker to the “on” position.

q5. Switch the system enable switch to the “on” position. Note: The Power Array may make a series of clicking sounds as it runs through an initial self test.
