10 ELECTRIC WIRING

10.1 GENERAL CHECK

1 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.
2 Following the Council Directive 2004/108/EC(89/336/
EEC), relating to electromagnetic compatibility, next table
indicates: maximum permissible system impedance Z

• Check to ensure that screws for terminal block are tightly tightened.
-
• Check to ensure that the the outdoor fan has 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.

(KVA)
• 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.

• Check that the earth wire is securely connected, tagged and
locked in accordance with national and local codes.
