Connecting Adept 550 Robot to Power Chassis

The cable between the robot and power chassis is called the "motor power" cable. It has a
circular connector with a ground wire on the robot end and two square connectors on the
power chassis end. This cable carries high-voltage DC power to the motors. This indepen-
dent AC circuit can only be isolated using the circuit breaker on the front of the Adept
PA-4 power chassis.
WARNING: Turn off the power to the power chassis before installing or
removing any cables. Failure to observe this warning could cause injury
or damage to your equipment.
Do not turn on the power chassis without installing the motor power
cables. Dangerous AC and DC voltages may be present at the "Motor
Power Output" connectors on the amplifier modules.
1. Connect the circular end of the motor power cable to the matching connector on
the back plate of the robot. Tighten firmly by hand only. See Figure 5-5 and
Figure 5-6.
2. Install the motor power cable ground wire (comes out from the end of the cable
next to the circular connector) to the ground wire installation point at the bottom
of the back plate of the robot.
a. Remove the screw and the external-tooth lock washer from the ground wire
installation point.
b. Place the external-tooth lock washer against the back plate over the empty
hole, then place the ground wire lug over the washer. See Figure 5-6.
c. Install the screw and secure tightly.
CAUTION: Make sure that the ground wire lugs from the motor power
and signal cables are securely fastened to the robot back plate, with the
!
external-tooth lock washer located next to the back plate. Failure to secure
the ground wire lug will cause damage to the robot.
