WARNING
• Do not remove the drive cover for wiring or
periodic inspections while power is applied or
the unit is in operation. Electric shock may occur
from the exposed terminals.
• Wait at least 1 minute after disconnecting the
input power before performing any wiring tasks
and/or periodic inspections of the drive.
• Operate the Vari-Green motor and control
devices with dry hands.
• Do not use this device if power or motor cable is
damaged.
• As this is a permanent magnet motor, this motor
will generate voltage when the shaft is rotated.
Shaft must be locked out for safe servicing.
CAUTION
• Disconnect the input power if the Vari-Green
motor has been damaged. Failure to do so
may result in fire and/or secondary damage or
accidents.
• Do not touch the Vari-Green motor immediately
after shutting down or disconnecting it. It can
remain hot for a few minutes. Bodily injuries such
as skin-burn or damage may occur.
• Do not apply power to a damaged Vari-Green
motor or to a Vari-Green motor that is missing
parts.
• Do not allow lint, paper, wood chips, dust,
metallic chips or other foreign material into the
drive as it may cause fire or accident.
Vari-Green Controls all use a 0-10 VDC control signal
to provide a speed reference to Vari-Green Motors.
See below for typical Vari-Green wiring. Reference
the individual controls Installation, Operation and
Maintenance Manual for programing, wiring and
troubleshooting of that control.
