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,


to the relay coil.
Do not short the analog voltage terminals H

and L or the internal power terminals P24 and
all CM's to prevent any VFD damage
When connecting a thermistor to the TH and

