■ Attention

1. Electrical work must be carried out safely and reliably by a professional electrical contractor (properly qualified electrician) in accordance with

internal wiring provisions and electrical-equipment technical standards.

2. Use 220 to 240 V AC Power.

3. Use the designated electric wires, and connect them securely so that they do not come loose.

4. Be sure to install the ground wire.

5. Install an all-pole power supply isolator at the power supply side as per local electrical regulations. All supply circuits must be disconnected before

obtaining access to the terminal devices. Use the specified size cable and connect the cables securely to prevent disconnection when they are pulled.
