Installing an electromagnetic contactor

When controlling the power on/off operation of the robot controller using an external unit such
as a PLC, an electromagnetic contactor should be installed on the AC power supply line for the
controller. Select an electromagnetic contactor that falls under the required safety category and
control the open/close operation using a circuit that meets the safety category. In this case, separate
the main power supply line from the control power supply line, and install the electromagnetic
contactor on the main power supply side.
To control the operation using emergency stop, turn the main power on and off.
