ABB IRB 1660 - Using the Brake Release Unit with an External Power Supply

Using the brake release unit with an external power supply
This section details how to release the holding brakes with the internal brake
release unit using an external voltage supply. This is done if the robot is not
connected to the controller.
NoteAction
Also, be careful not to interchange the
24V and 0V pins. If they are mixed up,
damage can be caused to a resistor di-
ode and to the system board.
DANGER
Incorrect connections, such as supplying
power to the wrong pin, may cause all brakes
to be released simultaneously!
