For 100-240 V AC rated equipment, protection for earth fault is provided by a 20 A max-

imum branch circuit from AC input in the building installation. The protection in the build-

ing installation is relied upon for short-circuit backup protection.

– The specification for AC breaker is 5 A, 2P, 277 V AC (min) circuit breaker, thermo-

magnetic or equivalent type.

– The plug connector and wire gauge sizing is to be selected with appropriate design as

per the electrical code for a 60 W, 1-phase device.

All equipment must be installed according to applicable local wiring codes and standards.

Always use conductors that are rated for the operating ambient temperature of 85°C.

Note for IT power distribution systems:

– This product is also designed for IT power distribution system with phase-to-phase

voltage 230 V.

– This equipment must be connected to an earthed mains socket/outlet.

To connect the power source:

1. Remove the transparent plastic finger-safe cover from the terminal block.
