General Safety Instructions
These safety instructions are intended for all work on the HG7. Additional safety instructions are
provided at appropriate points on other sections of this manual.
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 HG7 harmonic 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 HG7 filter.
Warning The HG7 harmonic filter, drive, motor, and other connected
equipment must be properly grounded.
Warning After switching off the power, always allow 5 minutes for the
capacitors in the HG7 filter and in the drive to discharge before
working on the HG7, the drive, the motor, or the connecting
wiring. It is a good idea 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.
