ATTENTION:
When relay coil voltage is lower than 24V, a resistor as voltage divider should be mounted
between relay and output terminal, based on coil impedance.

Wiring instruction of relay output terminal
Control boards of FR500A&FR510A series drives are provided with two programmable relay dry
contact outputs. One relay contacts are R1A/R1B/R1C, whose R1Aand R1C are normally open, while
R1B and R1C are normally closed. See parameter F05.02 for details.
The others contacts are R2A /R2B/R2C, whose R2A and R2C are normally open, while R2B and
R2C are normally closed. See parameter F05.03 for details.
ATTENTION:
In case inductive load (e.g. electromagnetic relay or contactor) is to be driven, a surge voltage
