 NOTE:
- Follow local codes and regulations when selecting eld wires, Circuit breakers and Earth Leakage breakers
- Use the wires which are not lighter than the ordinary polychloroprene sheathed exible cord (code designation H05RN-F)

13.3.3. H-LINK II SYSTEM
 NOTE:
The H-LINK II system can not be applied to the cycle with the old
H-LINK model.
1. Application
The new H-LINK II connecting each indoor unit and outdoor unit for
up to 64 refrigerant cycles (up to 160 indoor unit per H-LINKII), and
connecting wires for all indoor units and all outdoor units in series.
2. Specications
- Transmission Wire: 2-Wire
- Polarity of Transmission Wire: Non-Polar Wire
- Maximum Outdoor Units To Be Connected: 64 Units per
H-LINK II system.
- Maximum Indoor Units To Be Connected: 160 Units per
H-LINK II system
- Maximum Wiring Length: Total 1000m (including CS-NET). In
case that the total wiring length is longer than 1000m, contact the
Hitachi dealer.
- Recommended Cable: Twist Pair Cable with Shield, over
0.75mm2 (Equivalent to KPEV-S)
- Voltage: DC5V
 NOTE:
Do not make a wiring in a loop.
3. Dip Switch Setting of Indoor PCB and Outdoor PCB
It is required to set dip switches of every indoor unit and outdoor unit.
