Figure 2-7: Power and Control Circuit Cabling Diagram
Control circuit wires are insulated from
power lines (R,S,T,U,V,W)
Use twisted screened cable for input and
output wires of the control circuit terminals
Limit the connection wires to 65 feet
Separate the control circuit wiring from the
main power and relay control wiring
When using relays for the FW terminal or an
intelligent input terminal, use a control relay
that is designed to work with 24 Vdc.
When a relay is used as an intelligent
output, connect a diode for surge protection
parallel to the relay coil.
Do not short the analog voltage terminals H
and L or the internal power terminals P24
and all CM1 or CM’s to prevent any VFD
damage
When connecting a thermistor to the TH and
all CM1 or CM’s terminals, twist the
thermistor cables and separate them from
the rest. Limit the connection wires to 65
feet.
