[WIRING PRECAUTIONS]
Always confirm the products terminal layout before wiring to the module.
Incorrect wiring could lead to fires or faults.
Tighten terminal screws to the specified torque.
If a terminal screw is not tightened to the specified torque, the module may
fall out, short circuit, or malfunction. If a terminal screw is tightened
excessively, exceeding the specified torque, the module may fall out, short
circuit, or malfunction due to breakage of the screw or the module.
Make sure that no foreign matter such as chips or wire offcuts gets inside
the module. It will cause fire, failure, or malfunction.
AS-i cables connected to a module must always be run in a duct or held
securely using clamps.
If a cable is not run in a duct or not held securely using clamps, the cable
will sag, move, or be pulled by mistake, which will cause damage to the
module and the cable and also malfunctioning due to loose connection of
the cable.
When removing the AS-i cable from a module, do not pull it out by the cable.
A cable loosen the screws that hold the cable onto the module then
remove the cable.
If the cable is pulled while it is connected to the module, the module and/or
the cable will be damaged and may malfunction due to loose connection of
the cable.
Use applicable solderless terminals and tighten them within the specified
torque range. If any spade solderless terminal is used, it may be
disconnected when the terminal screw comes loose, resulting in failure.
