[WIRING PRECAUTIONS]
!
CAUTION
Be sure to ground the FG terminals and LG terminals to the protective ground conductor. Not
doing so could result in electric shock or erroneous operation.
When wiring in the PLC, be sure that it is done correctly by checking the product's rated voltage
and the terminal layout. Connecting a power supply that is different from the rating or incorrectly
wiring the product could result in fire or damage.
External connections shall be crimped or pressure welded with the specified tools, or correctly
soldered. Imperfect connections could result in short circuit, fires, or erroneous operation.
Tighten the terminal screws with the specified torque. If the terminal screws are loose, it could
result in short circuits, fire, or erroneous operation. Tightening the terminal screws too far may
cause damages to the screws and/or the module, resulting in fallout, short circuits, or
malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris inside the module.
Such debris could cause fires, damage, or erroneous operation.
The module has an ingress prevention label on its top to prevent foreign matter, such as wire
offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat dissipation.
[STARTUP AND MAINTENANCE PRECAUTIONS]
!
DANGER
Do not touch the terminals while power is on.
Doing so could cause shock or erroneous operation.
Correctly connect the battery.
Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery.
Mishandling of battery can cause overheating or cracks which could result in injury and fires.
Switch all phases of the external power supply off when cleaning the module or retightening the
terminal or module mounting screws. Not doing so could result in electric shock.
Undertightening of terminal screws can cause a short circuit or malfunction. Overtightening of
screws can cause damages to the screws and/or the module, resulting in fallout, short circuits,
or malfunction.
