Wiring the Power Supply

21

The power supply should be wired by securely connecting the terminal on the rear of
the main unit to the terminal. Always use crimp terminals for wiring.

In order to minimize influence from noise, the wiring for the power supply should be
twisted.

– In order to protect the unit against abnormal voltage from the power supply line, the
power supply should be an insulated type, and should be enclosed within a protective
circuit.
– A non–insulated regulator is used with the GT series.
– If a power supply device without an internal protective circuit is being used, power
should always be supplied to the GT series through a fuse or a similar protective device.

Operating voltage range

21.6 to 26.4V DC

– The terminal screws are M3 screws. We recommend using crimp terminals for wiring
to terminals.
