Electric And Control Cables; Installation Of The Smart Control Panel - Swegon CASA R3 Smart Installation, Commissioning And Maintenance Instructions

2.4 Electric and control cables

The ventilation unit has a power cable with earthed plug.
The plug serves as the ventilation nit's main switch and
should be connected to an easily accessible wall socket.
There is a modular cable on top of the ventilation unit
to control the unit. The modular cable for the cooker
hood is located under the cover plate at the bottom
of the ventilation unit. The maximum length of the
modular cable is 40 metres. If you route the modular
cable within a building element, the cable must be
routed in a ∅ 20 mm conduit, bearing in mind any
subsequent cable replacement.
Ensure during the installation of the ventilation unit that
it is easy to access the cable connectors, among others,
for servicing and setting up.
Accessories are either connected to the ventilation
unit's four-way connector (2 extra functions) or to the
external connection modules (3 extra functions). The
cables are routed through the cable entries that are
inside and on top of the ventilation unit. The connection
of accessories is described in the section "External
connections". Connection cables to connection modules
and accessories are not included in the supply.

2.5 Installation of the Smart control panel

A maximum of two Smart control panels can be con-
nected to the ventilation unit. These should be con-
figured with different ID numbers (Settings/Display/
Display ID). A Smart control panel can be mounted up
to 40 metres from the unit (using 2 x 20 metre long
modular cables).
The front panel on the Smart control panel is released
using a screwdriver to push the retaining clips through
the holes on either side.
If several control panels are connected in chain, the
middle panel's bus termination is moved to the "Open"
position. The jumpers do not need to be adjusted if only
one control panel is used.
Bus termination: Terminated
The modular cable can be connected to any outlet
socket on the panel.
Finally, refit the front panel.
