3) The maximum wiring length should be 30m (98.43feet).
4) Do not short across terminals PC and SD. Inverter may be damaged.
5) Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults when using contact inputs since the control circuit input signals
are micro-currents.
6) 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).
7) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
8) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.
