[Wiring Instructions]
• Always ground the FG and LG terminals to the protective ground conductor. Not doing so could
result in electric shock or malfunction.
• Before wiring the module, confirm the rated voltage and terminal layout of the product.
Connecting a power supply that is different from the rating or incorrectly wiring the product could
result in fire or failure.
• External connectors should be crimped or pressure-welded with the specified tools, or correctly
soldered. Imperfect connections could result in short circuit, fires or malfunction.
• Tighten the terminal screws in the specified torque range.
Undertightening could result in short circuit, fire or malfunction.
Overtightening could cause damage to the screws and/or the module, resulting in drop, short
circuit or malfunction.
• Be careful not to allow foreign matter such as chips and wire off-cuts to enter the module.
Foreign matter could cause fire, failure, or malfunction.
• 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/Maintenance Instructions]
• Do not touch the terminals while power is on.
Doing so could cause electric shock.
• Correctly connect the battery. Do not charge, disassemble, heat, place in fire, short circuit, or
solder the battery.
Mishandling of the battery can cause heat generation, burst or ignition which could result in
injury or fire.
• Always turn off the external power supply completely before 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 damage to the screws and/or the module, resulting in drop,
short circuit, or malfunction
