Section 6 - Operation 6.1 Restoring For Service
When wiring connections have been completed (or after maintenance or repair operations are finished) it will be
necessary to perform several tasks before the power conditioner can be put into service. Take these steps in the
following order:
1. Verify that all electrical connections are tight.
2. Verify that the enclosure, transformer and all other internal components are free of metal shavings, debris,
and installation/maintenance tools.
3. Replace any front, top, rear, or side panels that have been removed.
4. Disengage the lockout/tagout provision at the source (if engaged).
5. Disengage the lockout/tagout provision on the front panel circuit breaker of the power conditioner.
A bonding strap is attached to the bottom of each side panel with a hand fastener
and lock-washer. The bonding strap electrically grounds the side panel to the
frame during normal operation. This bonding strap must be reconnected to the
side panel when the side panel is replaced. Failure to reconnect the ground strap may result in an
electrical shock hazard in the event of an electrical fault.
6.2 Energizing the Power Conditioner
Once the power conditioner has been installed, it’s time to apply power and verify its proper operation. Perform
the following steps:
1. If equipped with the harmonic mitigation option, turn on the harmonic filter circuit breaker.
2. Rotate the front panel circuit breaker’s rotary handle one quarter turn clockwise to the “On” or red position.
3. Verify that the green “power on” LED is illuminated and the red TVSS Fault LEDs are extinguished (this is the
normal state for the front panel LEDs).
4. If equipped with either the basic metering or the power management option, verify that the Power
Measurements device is powered on and operating. If so equipped also verify steps 6 and 7 below. If not
equipped with either option, proceed to Section 6.3.
5. Using the keypad on the Power Measurements device, verify the that phases A, B, and C are present.
6. Verify that phases A, B, and C each show the correct nominal voltage for the load being powered. Voltages
must match the voltage requirements of the load.
NOTE: The installer may verify the output voltage of the power conditioner using an appropriate
voltmeter at either the output receptacles of the power conditioner (if so equipped) or at the input power
terminals inside the connected load. This final step is recommended prior to energizing the load.
