Remember when servicing the HPV900 Series 2: 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 (B1) and (-) 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.
