3.1. Wiring Precautions

3.1 Wiring Precautions
Take due precautions against wiring noise especially for HS pulse input.
1. Be cautious to do action about external noise during wiring for the pulse input of
the high counter module.
27. Use twisted pair-shielded class 3 grounded wire.
28. Keep the wiring away from power cable or I/O line to avoid any inductive noise.
29. Stabilized power must be used for filtering unwanted signal.
30. Connect A-phase only for 1-phase input.
Example of DC5V Voltage Output Wiring
1. If the pulse generator is of voltage output type, example of wiring with HSC is
shown in Figure 21.
31. The wiring is identical if the pulse generator of voltage output type is used through
Totem Pole output.
32. Wiring of the preset signal is identical to the gate signal.
