2.2 Wiring the Power Supply

 

 

2.2Wiring the Power Supply

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.

Use twisted wiring for the power supply

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

Insulate the power supply inside a protective circuit

–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.

Keep the power supply voltage within the operating voltage range

Operating voltage range

21.6 to 26.4V DC

 

 

Use M3 crimp terminals

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

The tightening torque for terminal base screws should be between 0.5 and 0.6 N·m, or less. Operating at a higher force could cause damage.

If crimp terminals are not being used, wire with a diameter of 0.5 mm2 to 1.25 mm2 should be used for power cables.

For precautions concerning conformance to European EMC di- rectives, please see “Power Supply Terminals” on page 10.
