10 - CONNECTIONS
Recommendations concerning electrical connections of the indoor unit.
Connect the indoor unit so that the main power supply comes from underneath the unit.
Either on the right side of the unit (1 or 2) or from underneath (3). If using a cased base, pass it through one of the grommets on
the right side intended for this purpose (See technical characteristics in paragraph 12.2.5).
Then follow the routing shown in the figures below.
CW model
When wiring via management systems (CMS) or master/slave control, as well as room sensors, go through the top of the cabinet
and the top section of the box, through the grommets shown in the box views.
In all cases, avoid following the power supply cables, to avoid interference to the signals sent.
Recommendations concerning the cables and routing in the box.
- For the communication cables:
• BUS RS485 cable: Multiconductor shielded jacketed cable (shielding with braiding)
- BUS RS485 cable for MODBUS or master/slave communication.
- BACNET BUS cable for BACNET communication (see BACNET specification)
- For the room sensor cables:
• Multipolar shielded cables of 3 to 5 wires with a maximum cross section of 1.5 mm2.
Please refer to the control manual and electrical diagram for more details concerning connection.
