4) Cautions for wiring
To avoid any troubles caused by noise, strictly observe the following cautions when per-
forming the wiring.
(1) If the noise may affect adversely, prepare the power supply for each manifold solenoid
valve where possible and perform the wiring individually.
(2) Do not use a long power cable if it is not necessary. Make the wiring distance as short
as possible.
(3) Do not connect devices producing noise, such as inverter or motor to the same power
supply for the manifold solenoid valve.
(4) Do not connect the power supply and signal cables in parallel to other power cables.
Since connecting the electric wires that were only twisted direct to
the terminal strip may cause firing, be sure to use a crimp terminal.
Connect the power supply always after checking the polarities of
serial transmission unit block terminal and cable terminal.
Before selecting the power cable, always calculate the current con-
sumption.
Where the power is supplied to several serial transmission unit
blocks and remote stations from a single power source, cable selec-
tion and wiring are required with due consideration given to voltage
drop caused by the electric wire.
When such voltage drop is unavoidable, pluralize the power lines,
provide another power source, and take other measures therefor,
and also maintain the power supply voltage as specified.
