DANGER
Heed the safety messages in this manual.
Failure to comply will result in serious injury or death.
The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings
in this manual.
Danger - High Voltage Shock Hazard.
Failure to comply will result in serious injury or death.
Motor control equipment and electronic controllers are connected to hazardous line potentials. When servicing drives
and electronic controllers, there may be exposed components with their cases and protrusions at or above line potential.
Extreme care should be taken to prevent against electrical shock.
Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with
another person in case an emergency occurs. Disconnect power and wait the proper amount of time for the DC bus
capacitors to discharge to a safe level of 50 Vdc or less and 0 Vac on 4PCB TB1 on the power supply unit before
servicing the controller.
Be sure equipment is properly grounded. Wear safety glasses whenever working on an electronic controller or electrical
rotating equipment.
