Wiring

How to connect wires

Read the following precautions before connecting any

wires to the unit. Follow these tips when wiring the unit.

(1) Twisting cables will decrease the effects of

induction.

(2) Introducing a 1:1 isolation transformer or noise filter

into the line will decrease power line noise.

(3) Make wire lengths as short as possible. Separate

wires from power lines and signal lines that contain noise.

*Tightening torque: 5.1 lb-in Wire Rating: AWG #22 - 14, stranded wire only, Copper wire only, 60˚C or higher
