control switch must be installed for each set.
• Grounding requires more than 3 grounding points and must
be wired for safety purposes.

• After wiring power line to terminal box, check if the line touches tightening bolt or
clamp or is being forced.
• Use regulated electric wire so connecting part of terminal is knocked out by external
force. It can cause fire if connecting part is fixed tightly as it generates heat.
• Wire power line after ring terminal work. It can cause fire and failure of electric parts.
• Check Neutral status when installing main power
• Ending part of PLS has to be waterproof when connecting it to terminal.
