7.3 Connecting outdoor unit
7.3.1 A-Version
Condensers (DMOUCD) that are supplied with A-Version Multi-DENCO units are pro-
vided with their OWN SEPARATE ISOLATOR.
For condensers, the following power and controls layouts are possible:
Fig. 7-4: EC fan installation
* Not available in size 008
** For AC units, Fig. 7-4 does not apply. Power cables must be installed for each condenser and connected to the indoor unit separately.
We recommend any 2 core screened data cable for control wiring, for example:
– Belden 8761
– Alpha 2401C
– BICCH8082
NOTE!
We STRONGLY recommend that the outdoor unit should be connected to the
indoor unit for its power supply.
