Instructions for wiring of the control circuit terminal
Terminals 5, SD and SE are common to the I/O signals and isolated from each other. Do not earth (ground).
Avoid connecting the terminal SD and 5 and the terminal SE and 5.
It is recommended to use the cables of 0.75mm² gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm² or more, the front cover may be lifted when there are many cables running or the
cables are run improperly, resulting in an operation panel contact fault.
The wiring length should be 30m maximum.
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.
To suppress EMI, use shielded or twisted cables for the
control circuit terminals and run them away from the main
and power circuits (including the 200V relay sequence circuit). For the cables connected to the control circuit terminals,
connect their shields to the common terminal of the connected control circuit terminal. When connecting external power
supply to the terminal PC, however, connect the shield of the power supply cable to the negative side of the external
power supply. Do not directly earth (ground) the shield to the enclosure, etc.
Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.
