Degree of protection: IP20

Connection: Euro terminal block (torque 0.3 N·m)

Grounding: DIN Rail

Housing material: Flame-resistant resin (black)

Monitor LED: Green LED turns ON when the voltage is

supplied; OFF when the safety fuse is blown.

INSTALLATION

AC power supply: Max. output current 3 A

Caution: Use an AC power source with the overload current

protection function.
