FRENIC-HVAC Control Wiring
*1) To retain an alarm output signal ALM issued on inverter's programmable output terminals by the protective
function or to keep the keypad alive even if the main power has shut down,
connect these terminals to the power supply lines. Even without power supply to these terminals, the inverter
can run.
*2) Terminals [Y1] to [Y4] (transistor outputs) support both SINK and SOURCE modes.
*3) When the Enable function is not to be used, short-circuit terminals [EN1] and [PLC] and terminals [EN2] and
[PLC] using jumper wires. For opening and closing the hardware circuit between terminals [EN1] and [PLC] and
between [EN2] and [PLC], use safety components such as safety relays and safety switches. Be sure to use
shielded wires exclusive to terminals [EN1] and [PLC] and terminals [EN2] and [PLC]. (Do not put them together
with any other control signal wire in the same shielded core.)
*4) Usually there is no need to do anything regarding the EMC filter.
When the leakage current due to the built-in EMC filter causes problems with the power supply system,
removing screws from terminals [E1] and [E2] may improve the problem.
Note that doing so the effect of the EMC filter is lost, and therefore the inverter is no longer compliant with the
EMC standards. To remove those screws, consult your Fuji Electric representative.
*5) Normally there is no need to connect it. Must be connected if inverter is supplied from regenerative PWM
converter (RHC Series) or from DC power supply.
