Remember when servicing the HPV 600: Hazardous
voltages may exist in the drive circuits even with drive
circuit breaker in off position.
IMPORTANT: Use extreme caution: Do not touch any
circuit board, the drive, or motor electrical connections
without making sure that the unit is properly grounded
and that no high voltage is present.
NEVER attempt maintenance unless:
•
the incoming three phase power (460 or 230VAC)
is disconnected and locked out.
•
also, ensure the DC Bus charge light is out.
•
even with the light out, we recommend that you use a voltmeter between (N) and (P) to verify that
no voltage is present.
CAUTION: Before continuing, ensure the DC Bus Charge LED is not illuminated.
IMPORTANT: Take ESD precautions, devices within the drive are sensitive to static damage.
