[Wiring Precautions]
CAUTION
Be sure to shut off all phases of the external power supply used by the
system before installation or wiring.
Failure to do so may cause a damage to the product and/or malfunctions.
Always ground the FG terminal to the protective ground conductor.
Failure to do so may result in malfunctions.
Be sure to tighten any unused terminal screws within a tightening torque
range.
Failure to do so may cause a short circuit due to contact with a solderless
terminal.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderless spade terminal is used, it may be disconnected when the
terminal screw comes loose, resulting in failure.
Check the rated voltage and terminal layout and then wire the module
correctly.
Connecting a power supply of a different voltage rating or incorrect wiring
may cause a fire or failure.
Tighten terminal screws within the specified torque range.
A loose terminal screw may cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to damage of the
screws or module.
Take care to prevent foreign matter such as dust or wire chips from entering
the module.
Failure to do so may cause a fire, failure or malfunctions.
Place the connection wires and cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables or malfunctions due to poor cable
connection.
