Pre-Operation Checks
Before Applying Power:
♦ Read the Safety section at the front of the Manual.
♦ Ensure that all local electric codes are met.
♦ Check for damage to equipment.
♦ Check for loose ends, clippings, drilling swarf etc. lodged in the drive and system.
♦ Check all external wiring circuits of the system - power, control, motor and earth connections.
♦ Ensure that unexpected rotation of the motor in either direction will not result in damage, bodily harm or
injury. Disconnect the load from the motor shaft, if possible.
♦ Check the state of the Motor Thermistor and Brake Resistor connectors. Check external run contacts are
open. Check external speed setpoints are all at zero.
♦ Ensure that nobody is working on another part of the system which will be affected by powering up.
♦ Ensure that other equipment will not be adversely affected by powering up.
♦ Check motor stator connections are correctly wired for Star or Delta as necessary for drive output
voltage.
