7.2.2 Connection of Power Supply
Power to the separate detector interface unit should be supplied from
an external 24 V DC power supply. An extended unit is powered by
a basic unit.

Recommended cable specification: A02B-0124-K830 (5 m)
(The external power supply end of the cable is provided with M3 crimp terminals.)
Select a connector that
matches the pin layout of
the external power supply.

The 24 VDC input to CP11A can be output at CP11B for use in
branching. The connection of CP11B is identical to that of CP11A.
In this case, the power supplied to CP11A should be equal to the sum
of the rating of the separate detector interface unit and that of the units
after CP11B.
Be sure to ground the 0-V line of the power supply to the separate
detector interface unit. In addition, keep any noise source (such as
an AC power cable and contactor) away from the power line of the
separate detector interface unit as far as possible to prevent noise from
being picked up through the power line.
Secure the ground line to the ground terminal (GND) for signals of a
separate detector interface unit, which is located at the bottom of the
unit, with an M3 screw as shown in the figure below. Connect the
ground line to the ground plate of the cabinet.
