Electrical Requirements
Refer to the electrical diagram provided with the unit before starting any installation or
maintenance work.
Do not operate vacuum pump on a voltage other than the voltage specified on the control panel nameplate.
All customer wiring should be in compliance with the National Electrical Code and any other applicable state
or local codes.
Refer to the wiring diagram(s) that came with the vacuum pump system for pertinent wiring connections.
Ground the control panel and the motor frame solidly. Do not use the system piping for the ground.
Electrical power for the medical system must be supplied from the emergency life support circuit.
Check the control voltage, phase, and amp ratings before starting the electrical installation, and make sure the
voltage supplied by the hospital is the same. The wire size should be able to handle peak motor amp load of all
operating units. Refer to the vacuum pump system full load amperes on the wiring diagram.
Check all electrical connections within the vacuum system that may have loosened during shipment.
Only certified electricians should make power connections to the control panel and any interconnecting wiring.
Ensure that the emergency generation system electrical supply is consistent with the vacuum system’s requirements.
The electrical controls for the system were wired at the factory and were fully tested.
Three-phase power supplied from emergency generator(s) must match that of the normal supply to allow for correct
direction of the motor rotation at all times.
NOTE
