1. Using the specified wires, ensure to connect the wires, and fix wires securely so that
the external strength of the wires do not transmit to the connecting part of the
terminals.
Incomplete connection or fixation may cause fire, etc.
2. For electric work, strictly follow to the Local Regulation in each country and the
Installation Manual, and use an exclusive circuit.
