Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with these instructions will result in voiding of the product warranty and may result in personal injury and/or property damage. General Information The Vari-Green Drive (VGD) is a factory mounted WARNING.

2 And wired variable frequency drive. It is compatible with induction and permanent magnet motors. Do not remove VGD cover for wiring or periodic It is programmed at the factory to match the inspections while power is applied or the unit is in characteristics of the fan and motor on which it is Operation . Otherwise, electric shock could occur installed. from the exposed terminals and bus bars. Wait at least 1 minute after disconnecting the input power and also verify all LEDs including the Power and Charge LEDs are off before performing Safety Instructions any wiring tasks and/or periodic inspections on the VGD.
