6. ELECTRICAL WIRING WORK
5.
Drainage
Electrical installation work must be performed by an electrical installation service provider qualified by a power provider of the country.
Electrical installation work must be executed according to the technical standards and other regulations applicable to electrical installations in the country.
Please install an earth leakage breaker without fail
. The installation of an earth leakage breaker is compulsory in order to prevent electric shocks or fire accidents.
(Since this unit employs inverter control, please
use an impulse withstanding type
to prevent an earth leakage breaker’s false actuation.)
Please note
a) Use only copper wires.
Do not use any supply cord lighter than one specified in parentheses for each type below.
- braided cord (code designation 60245 IEC 51), if allowed in the relevant part 2;
- ordinary tough rubber sheathed cord (code designation 60245 IEC 53);
- flat twin tinsel cord (code designation 60227 IEC 41)
- ordinary polyvinyl chloride sheathed cord (code designation 60227 IEC 53).
Please do not use anything lighter than polychloroprene sheathed flexible cord (cord designation 60245 IEC57) for supply cords of parts of appliances for outdoor use.
b)
Use separate power supplies for the indoor and outdoor units
.
c) A grounding wire must be connected before connecting the power cable. Provide a grounding wire longer than the power cable.
d)
The power supplies for indoor units in the same system should turn on and off simultaneously
.
e) Ground the unit. Do not connect the grounding wire to a gas pipe, water pipe, lightning rod or telephone grounding wire.
If improperly grounded, an electric shock or malfunction may result.
Never connect the grounding wire to a gas pipe because if gas leaks, it could cause explosion or ignition.
f)
The installation of an impulse withstanding type earth leakage breaker is necessary
. A failure to install an earth leakage breaker can result in an accident such as an
electric shock or a fire. Do not turn on the power until the electrical work is completed. Be sure to turn off the power when servicing.
g) Please do not use a condensive capacitor for power factor improvement under any circumstances. (It does not improve power factor, while it can cause an abnormal
overheat accident)
h) For power supply cables, use conduits.
i) Please
do not lay electronic control cables (remote control and signaling wires) and other high current cables together outside the unit
. Laying them together can
result in malfunctioning or a failure of the unit due to electric noises.
j) Power cables and signaling wires must always be connected to the power cable terminal block and secured by cable fastening clamps provided in the unit.
k) Fasten cables so that they may not touch the piping, etc.
l)
When cables are connected, please make sure that all electrical components within the electrical component box are free of loose connector coupling or terminal
connection
and then attach the cover securely. (Improper cover attachment can result in malfunctioning or a failure of the unit, if water penetrates into the box.)
m) Make sure to use circuit breakers (earth leakage breaker and circuit breaker) of proper capacity. Use of breakers of larger capacity could result in trouble on
components or fire accident.
n) Install isolator or disconnect switch on the power supply wiring in accordance with the local codes and regulations.
o) After maintenance, all wiring, wiring ties and the like, should be returned to their original state and wiring route, and the necessary clearance from all metal parts
should be secured.
CAUTION
If the earth leakage breaker is exclusively for ground fault protection, then you will need to install a circuit breaker for wiring work.
