(2) Wiring
①
Above control signals are insulated to its power lines(R, S, T, U, V, W).
Do not connect those signalsto power lines or ground.
②
Use twisted screened cable, for the input and output wires of the control circuit terminals.
Connect the screened cable to the common terminal.
③
Limit the connection wires to 65 feet.
④
Separate the control circuit wiring from the main power and relay control wiring.
⑤
When using relays for the FW terminal or an intelligent input terminal use a control relay that is
designed to work with 24Vdc.
⑥
When a relay is used as an intelligent output, connect a diode for surge protection parallel to the
relay coil.
⑦
Do not short the analog voltage terminals H and L or the internal power terminals P24 and all
CM1’s. Otherwise there is risk of Inverter damage.
⑧
When connecting a thermistor to the TH and all CM1’s terminal, twist the thermistor cables and
separate them from the rest. Limit the connection wires to 65 feet
