Grounding
The HarmonicGuard Active filter panel equipment-grounding lug must be connected to the ground of
the premises wiring system. The equipment grounding connection must conform to the requirements of
the National Electric Code (NEC) and/or any other codes that apply to the installation site. The ground
connection must be made using a wire conductor. Metallic conduit is not a suitable grounding
conductor. The integrity of all ground connections should be periodically checked.
HarmonicGuard Active Filter Operation
Adjustments
• The HGA has been factory calibrated and thoroughly tested. There is no need to make
any adjustments.
Start Up (Commissioning)
Caution
Thoroughly check the installation before applying power and operating the equipment for the
first time.
Before Applying Power for the First Time
Inspect the installation to make sure that all equipment has been completely and correctly
installed on accordance with the Installation Guidelines section of this manual.
• If it is a floor mount unit, check to see that it is securely anchored to the floor.
• Check the panel and the inside of the enclosure for any foreign objects, dirt, metal filings,
wire whiskers, and loose hardware.
• Verify that any covers or guards that were removed during installation were reinstalled.
• Ensure that the unit is properly grounded.
• Check for properly tightened connections.
General Operation
Please reference the Quick Start Guide in Section 1 for the first time power up procedure.
Warning
Since the HGA is an active filter, it is always operating whenever the power is applied.
Warning
Only qualified electricians should carry out all electrical installation and maintenance work on the
HarmonicGuard Active filter.
Disconnect all sources of power to the drive and HGA before working on the equipment. Do not
attempt any work on a powered unit.
Warning
Be aware everything ahead of the circuit breaker will still be energized. It is important to note
that the lack of lit LEDs does not necessarily mean that the HGA is not receiving power from an
external source.
