Warning
Be sure to read, understand, and follow all safety instructions.
Warning
Only qualified electricians should carry out all electrical installation and maintenance work on the
HarmonicGuard Active (HGA) filter.
Warning
All wiring must be in accordance with the National Electrical Code (NEC) and/or any other codes that
apply to the installation site.
Warning
Disconnect all power before working on the equipment.
Do not attempt any work on a powered HGA filter.
Warning
The HGA filter, drive, motor, and other connected equipment must be properly grounded.
Warning
The HGA filter may receive power from two or more sources.
Three-phase power is connected to the main input terminals of the HGA filter.
All of these sources of power must be disconnected before working on the HGA filter.
Warning After switching off the power, always allow 5 minutes for the capacitors in the HGA filter and in the
drive to discharge before working on the HGA filter, the drive, the motor, or the connecting wiring. It
is good practice to check with a voltmeter to make sure that all sources of power have been
disconnected and that all capacitors have discharged before beginning work.
