Installation

Wiring of Main Power Supply and Equipment Capacity

Indoor unit (1Ø, 220-240, 50Hz)
Outdoor unit (1Ø, 220-240, 50Hz)
1. Separate power supply lines for the indoor units from outdoor unit.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.)
when proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. The power cord size should
be 1 rank thicker taking into account the line voltage drops. Make sure the power-supply
voltage does not drop more than 10%.
4. Specific wiring requirements should adhere to the wiring regulations of the region.
5. Power supply cords of parts of appliances for outdoor use should not be lighter than poly-
chloroprene sheathed flexible cord.
6. Don't install an individual switch or electrical outlet to disconnect each of indoor unit sepa-
rately from the power supply.
WARNING
• Follow ordinance of your governmental organization for technical standard re-
lated to electrical equipment, wiring regulations and guidance of each electric
power company.
• Make sure to use specified wires for connections so that no external force is im-
parted to terminal connections. If connections are not fixed firmly, it may cause
heating or fire.
• Make sure to use the appropriate type of overcurrent protection switch. Note that
generated overcurrent may include some amount of direct current.
CAUTION
• Some installation site may require attachment of an earth leakage breaker. If no
earth leakage breaker is installed, it may cause an electric shock.
• Do not use anything other than breaker and fuse with correct capacity. Using
fuse and wire or copper wire with too large capacity may cause a malfunction of
unit or fire.
Installation Manual and a note on the value added Ssc
- In accordance with EN/IEC 61000-3-11, respectively EN/IEC 61000-3-12, it may be neces-
sary to consult the distribution network operator to ensure that the equipment is connected
only to a supply with Zsys≤Zmax, respectively Ssc ≥ minimum Ssc value.
- European/International Technical Standard setting the limits for voltage changes, voltage fluctua-
tions and flicker in public low-voltage supply systems for equipment with rated current ≤ 75A.
- European/International Technical Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage systems with input current ≤16A of >75A per phase.
