formed this electrical installation should complete this checklist and deliver it to the system operator.
q 1. Apply power to the system input, and measure voltage at the input terminal block. Record measured
voltages below:
L1-Neutral: ______________________

L3-Neutral: ______________________
q 2. Connect the PowerView display as shown below:
q 3. Switch the input circuit breaker and bypass breaker on, then switch the system enable switch on.
Note: The system will make some clicking sounds as it powers up, and may display fault messages on the PowerView
display. Disregard these messages at this time.
n Measured voltage must be between 184V and 265V. If it is not, STOP! Verify correct wiring from the
power source to the input wiring connections. Repeat step 1.

n Ensure all switches (system enable, maintenance bypass , input circuit breaker, and bypass circuit breaker)
are in the “off” or “stand by” position. Ensure all load equipment is turned off or is unplugged from the
Power Array.
