3.4.2 Wiring instructions
●
Use shielded or twisted cables for connection to the control circuit terminals and run them
away from the main and power circuits (including the 230V relay sequence circuit).
●
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.
●
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. In
no way must a voltage be short-circuited by these relay contacts.
●
It is recommended to use the cables of 0.3–0.75mm² gauge for connection to the control
circuit terminals.
●
The wiring length should be 30m maximum.
●
Do not short terminal PC and SD. Inverter may be damaged.
