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.)
6.3 Energizing the Load
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.
6.4 Orderly Shutdown
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.
