Ensure that the field-supplied electrical components (mains power switches, circuit breakers, wires, connectors and
wire terminals) have been properly selected according to the electrical data indicated. Make sure that they comply
with national and regional electrical codes.

This equipment complies with IEC 61000-3-12 provided that the short-circuit
power Ssc is greater than or equal to xx (see Ssc column) at the interface point
between the user’s supply and the public system. It is the responsibility of the
installer or user of the equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment is connected only to a supply
with a short-circuit power Ssc greater than or equal to xx (see Ssc column)

Check to ensure that the power supply voltage is /-10% of the rated voltage.
5
Check to ensure that power supply has an impedance low enough to warranty not reduce the starting voltage more
than 85% of the rated voltage.
6
Check to ensure that the ground wire is connected.
7
Connect a fuse of specified capacity.

• Check to ensure that screws for terminal block are tightly tightened.
• Check to ensure that the indoor unit fan and the RASC fan have stopped before electrical wiring work or periodical check is performed.
• Protect the wires, drain pipe, electrical parts, from rats or other small animals. If not protected, rats may damage unprotected parts,
and at the worst, a fire will occur.
• Wrap the accessory packing around the wires, and plug the wiring connection hole with the seal material to protect the product from
any condensed water and insects.
• Tightly secure the wires with the cord clamp inside the indoor unit.
• Lead the wires through the knockout hole in the side cover when using conduit.
• Secure the cable of the remote control switch with the cord clamp inside the electrical box.
• Electrical wiring must comply with national and local codes. Contact your local authority in regards to standards, rules, regulations, etc.
• Check that the ground wire is securely connected.
•
Connect a fuse of specified capacity.

• Do not connect of adjust any wiring or connections unless the main power switch is OFF.
• Check that the earth wire is securely connected, tagged and locked in accordance with national and local codes.

N O T E
Check and test to ensure that if there is more than one source of power supply, that all are turned OFF.
