9.2. Wiring and fitting capacities
(1) PUH-8, 10
Notes:
*1: Connect an earth leakage breaker to the power supply.
*2: Use earth leakage breakers designed exclusively for ground fault protection only in combination with a local switch or a circuit breaker.
*3: The overcurrent protector using a Class-B fuse is shown.
*4: Power supply cords and indoor unit/outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord. (Design 245 IEC 57)
*5: A switch with at least 3 mm contact separation in each pole shall be provided by the Air conditioner installation.
*6: The connection wiring between the outdoor and indoor units can be extended up to a maximum of 50 m.
*7: This device is intended for the connection to a power supply system with a maximum permissible system impedance ZMAX at the interface point (power
service box) of the user’s supply.
The user has to ensure that this device is connected only to a power supply system which fulfills the requirement above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
Warning:
Always use the designated cable for wiring, and connect it correctly. Secure
it so that the cable applies no external pressure to the terminal connection. If
the connection is faulty or the cable is not fully secured, overheating or fire
could result.
Caution:
•
Depending on the location of the unit, a current leakage breaker may be
required. If a current leakage breaker is not installed, electric shock could
result.
•
Do not use breakers or fuses with a capacity different from the correct
one. If large-capacity fuses, wire, or copper wiring are used, accident or
fire may result.
Table above is an example. The selection of other capacities should be deter-
mined in accordance with the relevant standards.
Types of cable/cord
•
Vinyl cab tire round cord: VCTF
•
Vinyl insulating vinyl sheath cable round type: VVR
•
Vinyl cab tire flat cord: VCTFK
•
Vinyl insulating vinyl sheath cable flat type: VVF
•
Vinyl insulating vinyl sheath cable for control: CVV
•
600 V vinyl cab tire cable: VCT
•
Vinyl insulating vinyl sheath cable for control: CVS
Warning:
Be sure to use specified cables and connect them firmly so that no external
wiring force is exerted on terminal connections. Loose connections may cause
heat or fire.
Caution:
•
Some installation sites may required installation of an earth leakage
breaker. Failure to install it may result in an electric shock.
•
Always use an earth leakage breaker and fuse with the specified capac-
ity. Use of a fuse with a capacity larger than that specified, or use of a
piece of wire or copper wire may cause breakdown or fire.

Using the conduit mounting plates
Conduit mounting plates are supplied in three sizes (ø27, ø34, ø40). Choose
the size of mounting plate that matches the outer diameter of the conduit being
used.
•
Tie up wirings with cable strap mounted at the panel and lead it to control box.

10.1. Address settings
Outdoor unit address settings
•
When controlling a group, the address must be set for each outdoor unit.
•
During address setting, set all the dip switches SW1 (3 - 6) on the board to
<when shipped from factory: all OFF>. (Address setting is not necessary for
1:1 or Free multi-component systems.)
•
Settings using SW1 are given below.
•
Please set the mutually different address, and prevent the start up simultane-
ously. (In case of connecting with PEH-16, 20)

10.2. Examples of refrigerant system address
setting
* Set the refrigerant system address of one outdoor unit to 00 for the power supply
to the remote controller.
(The refrigerant system address is set to 00 when shipped from the factory.)
Do not duplicate the refrigerant system address settings within the same system.
10.3. Capacity control setting method (PEH-
16, 20 only)
With the PEH-16, 20 which has two outdoor units, the capacity can be controlled to
0%, 50% or 100%.
This is set by setting the outdoor unit side dip switches as shown in the table below
before turning the power on.
