12.5 Routing

It is important to keep the power supply and the
transmission wiring separated from each other.
In order to avoid any electrical interference the distance
between both wiring should always be at least 50 mm.
12.5.1 Transmission wiring routing
The transmission wiring outside the unit should be
wrapped and routed together with the field piping.
Field piping can be routed from front or bottom of the
unit (going left or right). See "10.2 Connecting the
refrigerant piping".
Rules for transmission wiring routing
Be sure to follow the limits below. If the unit-to-unit
•
cables are beyond these limits, it may result in
malfunction of transmission:
- Maximum wiring length: 1000 m.
- Total wiring length: 2000 m.
- Maximum inter unit wiring length between outdoor
units: 30 m.
- Maximum number of branches: 16.
- Maximum number of outdoor units of other system
that can be connected: 7.
Up to 16 branches are possible for unit-to-unit
