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 VSX 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 C1.02 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 C1.03 for details.
ATTENTION:
In case inductive load (e.g. electromagnetic relay or contactor) is to be driven, a surge voltage
absorbing circuit such as RC absorbing circuit (note that its leakage current shall be less than holding
current of controlled contactor or relay), piezoresistor or fly-wheel diode etc. shall be mounted (be sure
to pay close attention to polarity in case of DC electromagnetic circuit). Absorbing devices should be
mounted close to the ends of relay or contactor.

3.8.3 RFI Short wiring instructions
If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off.
Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage
(according to IEC 61800-3) and reduce earth leakage current.
