Wiring

∗ Only basic insulation (Protection against Electric Shock Class I, Overvoltage

category II, Pollution degree 2) is provided on the control circuit terminals.

The supplementary insulation must be provided on the final product to comply

with CE Marking requirements.

COM NC NO

Relay output

0 to 5V

0 to 10V

4 to 20mA

♦ Terminal specifications: "Screw size: M3 (minus screw)"

♦ Frequency setting potentiometer (VR) specifications: "10kΩ, 1/4W or more

potentiometer"

♦ Relay output contact specifications: 1c no-voltage contact, 250VAC, 0.5A

(resistance load)

♦ Open collector output specifications: Maximum rating 50VDC, 50mA

Note 1) When using a 4 to 20mA signal for the frequency setting, always

connect a 200Ω, 1/4W resistor. (The inverter could be damaged if

the resistor is not connected.)

Note 2) Always read each function explanation for the parameters related to

each terminal before starting use.
