Wiring of control circuit

(1) Control circuit terminal layout
A1
PC AM
(2) Wiring method
Loosen the terminal screw and insert the cable into the terminal.
Screw Size: M3 Tightening Torque: 0.5N·m to 0.6N·m
2
Cable size: 0.3mm to 0.75mm
Screwdriver:Small flat-blade screwdriver (Edge thickness: 0.4mm/
Edge width: 2.5mm)
CAUTION
Undertightening can cause cable disconnection or malfunction.
Overtightening can cause a short circuit or malfunction due to
damage to the screw or unit.
(3) Wiring instructions
1) Terminals 5, PC and SE are common to the I/O signals and isolated from each other. Do not earth. Avoid
connecting the terminal PC and 5 and the terminal SE and 5.
2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and
power circuits (including the 200V relay sequence circuit).
3) Use two or more parallel micro-signal contacts or twin contacts to
prevent a contact faults when using contact inputs since the
control circuit input signals are micro-currents.
4) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.
6) It is recommended to use the cables of 0.75mm
If the cable gauge used is 1.25mm
the cables are run improperly, resulting in an operation panel contact fault.
7) The wiring length should be 30m maximum.
