TION AND CONNECTION
2-7 Connecting to the EXT. CN Connector
Connect an emergency stop circuit and a 24V power supply for I/O control to the EXT. CN connec-
tor. Make the necessary wiring hookup (see below) to the mating connector that comes with the
SRCP controller and then plug it into the EXT. CN connector. Make sure the wiring is correct since
miswiring may cause serious accidents such as fire. Regardless of whether I/O control is used or not,
24V power for I/O control must always be supplied to the EXT. CN connector.
The meaning and operation of signals assigned to each terminal on the EXT. CN connector are
explained in detail in Chapter 3, "I/O INTERFACE".
The mating connector for the EXT. CN terminal on the SRCP series controller is as follows:
Mating connector type No. : 733-104 (WAGO)
SRCP's EXT. CN connector type No. : 733-364
12

Slotted screwdriver
Terminal numbers are not actually
indicated, but designated from 1 to
4, from the left as viewed from the
front (wire insertion side) as shown
in the drawing.
To make the wiring hookup to the mating connector (WAGO 733-104), insert the wire lead into the
terminal slot while pressing down the internal spring with a slotted screwdriver through the top slot.
(If you have a dedicated tool, insert it into the smaller slot just above each terminal slot for wire
insertion to make a quick connection.

CAUTION
Regardless of whether I/O control is used or not, DC 24V power must be supplied to EXT. CN to enable robot
operation. If no power is supplied to EXT. CN, an alarm (06: 24V POWER OFF) is issued to prevent operation.
Power to EXT. CN must first be supplied before supplying AC power to the power supply terminal block. If this
order is reversed, an alarm (06: 24V POWER OFF) might be issued.
c
CAUTION
If you do not configure an emergency stop circuit, then short terminal No. 1 (EMG1) to terminal No. 2 (EMG2).
Unless these terminals are shorted, emergency stop is always activated to prohibit the robot from operating.

DANGER
Be sure to turn off the power to the entire robot system before doing any wiring to the SRCP
controller. Failure to do so may cause electrical shocks.
