Section 6 - Operation

(NOTE: Under "no load" conditions, the transformer in the power conditioner will "step up" the output

voltage a few percent. This design characteristic compensates for losses within the transformer once

actual load is applied. As a result, an output voltage that is slightly higher than the nominal input voltage

is normal under unloaded conditions.)

(NOTE: For further information on Power Measurements Limited meters or monitors, consult the

separate owner’s manual. A separate manual will accompany this document if the power conditioner is

equipped with either option.)

Power is now available to the load. Perform the following steps in the order shown.

1. Energize the load in accordance with any recommended load power-up procedures.

2. Verify the proper operation of the load and the entire system.

3. If equipped with the basic metering or the power management option, you may use the keypad on the Power

Measurements monitor, to observe and/or verify the following:

a) Load currents for Phase A, B, and C are properly indicated

b) All other monitor functions are operating normally. (A manual is included as Section 10 with this

document if the power conditioner is equipped with the power management option.)

If all connections have been properly made and correct operation of the system has been verified, normal

operations may begin. The power conditioner is now quietly providing full-time protection to your critical system.

In the event that the power conditioner is ever dangerously overloaded for any reason, the main circuit breaker

will shut off, removing power from the connected load.

To shutdown the power conditioner in an orderly manner, first turn off all connected loads. Then turn off the

power conditioner by rotating the handle of the front panel circuit breaker one quarter turn counter-clockwise to

the “off” position. Verify that the front panel green power LED is extinguished. No residual energy is stored after

then power conditioner is de-energized.
