Wiring
*1
Low indicates that the open collector output transistor is on (conducts).
High indicates that the transistor is off (does not conduct).
*2
Not output during inverter reset.
(3) Communication
(4) Control circuit terminal layout
(5) Wiring instructions
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
2
gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm
2
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.
7)
The wiring length should be 30m (98.43feet) maximum.
