Power condition and switchboard
configuration for PLS installation
• Because the power consumption per 1 set of PLS is high,
the cross sectional area of the switchboard must
appropriately be applied, and for stable operation, one
control switch must be installed for each set.
• Grounding requires more than 3 grounding points and must
be wired for safety purposes.

* PLS is not equipped with a terminal block. For installation, please get professional
assistance.
- Terminal Block Specification
(a) Rated Voltage: 250V or above
(b) Rated Power: 10A or above
(c) 3 way bolt fastening type
- After connecting power line to the terminal block, ensure that the power line makes
secure contact with fastening bolt or clamp and the power line is securely fastened.
WARNING
• 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.
