Electrical Wiring
6. Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F
which conform to CENELEC(HAR) rating specifi cations) or use the cables based
on IEC standard (245 IEC57, 245 IEC66).
7. When linking the outdoor units in a network, the following rules for bus terminators
must be observed.
Upon shipment the bus terminator is in shorted condition. When linking two outdoor
units, open the jumper from the bus terminator for only one of these outdoor units.
When linking more than two outdoor units, open the jumper from the bus terminator
for all but the fi rst and the last one in the same link wiring network.
For a system without link (no wiring connection between outdoor units), do not
remove the bus terminator bridge.
8. Do not install the inter-unit control wiring in a way that forms a loop.
9. Do not install inter-unit control wiring such as star branch wiring. Star branch wiring
causes faulty address setting.
10. If branching the inter-unit control wiring, the number of branch points should be
16 or fewer. (Branches that are less than 1m are not included in the total branch
number.)
