1-6-6. TB-3: POWER SUPPLY
The wire size for TB-3 is able to use AWG17 – 16, 1.75 mm
2
, and required using O type or Y type crimp
terminal. (Screw diameter 3.0 mm, tightening torque 0.6 Nm).
24V DC Input 0.5A min – 3.0A max
* Required install Fast blow Fuse.
* No ripple required, Max +-10 %
There is protection that does not break down with reverse wiring, but please be careful because
input of high voltage will damage the circuit.

1-6-7. NOISE AND GROUND ISOLATION
In any location there is always the potential for electrical noise interference and multiple ground paths.
Electrical noise can cause erratic system operation and is very difficult to find and isolate, ground
loops also cause unexpected operation as well as burn out components. In addition, mains voltage
stability can sometimes be questionable.
An isolation transformer between the mains and DigiPackⅢ can provide some relief from noise,
ground loops and wandering mains.
