Connecting AC Power to the Adept PA-4 Power Chassis

The Adept PA-4 power chassis provides amplified power signals to drive the robot
motors in an Adept robot system. The amplifier modules in the Adept PA-4 power chassis
receive control signals from the Adept MV controller. The amplifier modules then provide
the necessary current to drive the various robot joint motors.
The Adept PA-4 power chassis is shipped from the factory configured for either 380-415
VAC or 200-240 VAC operation, depending on your sales order. A voltage setting label is
located on the front of the chassis below the circuit breaker. The voltage setting is also
shown on the ID label on the side of the chassis. Verify that the setting matches your
facility power before installation. This chassis is designed for 3-phase operation only.
If you need to change the AC voltage setting from 380-415 VAC to 200-240 VAC, see
page 42.
WARNING: Electrical hazard!
Verify the voltage settings are correct before turning on power. Operating
the Adept PA-4 power chassis with incorrect voltage settings can cause
damage or injury.
