Definition of the pictograms used:
Electrical hazard: Fig. 3
Danger to hands: Fig. 4
General danger: Fig. 5
Comply with all safety rules and regulations currently in
force. Use safety goggles and safety gloves. Take care when
moving or positioning the equipment.

2.2 - Protection against electrocution

Only electricians qualified to the level recommended by
the IEC (International Electrotechnical Commission) in
its standard IEC 364, corresponding to Europe HD 384,
France NFC 15 100 and UK IEE Wiring Regulations, may
access the electrical components. In particular, it is
mandatory that all power supplies to the unit are switched
off before any work is carried out. Switch off the main
power supply using the disconnection device (not supplied
by Carrier).
IMPORTANT: The constituent components of the various
control systems available include electronics. As such,
they may generate or be harmed by electromagnetic
interference unless they are installed and used in
accordance with these instructions. The components
making up these control loops conform to the
electromagnetic compatibility requirements for
residential, commercial and light industrial
environments. They also comply with the low-voltage
directive.

2.3 - General recommendations for installation

IMPORTANT: controllers must have a disconnection
device upstream (for example a double-pole circuit
breaker). If necessary, an easily accessible emergency stop
device (such as a punch-button switch) must cut off the
power to all devices. They must be sized and installed as
per the recommendations of IEC 364, corresponding to
Europe HD 384, France NFC 15 100 and UK IEE
Wiring Regulations. These devices are not supplied by
Carrier.
As a general measure, the following rules must be applied:
Overcurrent protection upstream
Device without electrical heater
Device with electrical heater <2000W
Device with electrical heater >2000W
Units must be provided with earth leakage current
protection upstream (not supplied by Carrier).
A light-coloured marking must be made on the
disconnect device to show the devices connected to it.
The wiring of the components which make up the
different control systems and the communication
buses must be carried out in accordance with the
latest rules and regulations by professional installers.
8
The power supply cable must be double insulated and
secured with a pull-out resistant fastener, or the cable
tie supplied with the Carrier digital controller. The
power supply cable must be clamped on the outer
insulation.
The constituent components of these various control
loops must be installed in an environment which
complies with their index of protection (IP).
The maximum level of pollution is normally pollutant
(level 2) and installation category II.
The low-voltage wiring (communication bus) must be
kept physically separate from the power wiring.
In order to avoid interference with the
communication links:
-
Keep low-voltage wiring away from power cables
and avoid using the same cable run (a maximum
of 300 mm must be shared with the 230 VAC,
30 A cable).
-
Do not pass low-voltage wires through loops in
the power cables.
-
Do not connect heavy inductive loads to the same
electrical supply (circuit breaker) used by
controller or power module equipment.
-
Use the screened cable type recommended by
Carrier and make sure all cables are connected
to the controllers and power modules.
2.4 - Recommendation relating to the 36XB Hybrid
Air Terminal control
IMPORTANT: It is not permitted to connect several
36XB units to the same control device (wall thermostat,
electronic NTC, etc.).

2.5 - Conformity

This equipment has been declared compliant with the
essential requirements of the following directives:
Electromagnetic compatibility: 2004/108/EEC
• Low-voltage directive: 2006/95/EEC.

3 - INSTALLATION OF ThE UNIT

3.1 - Coordination between the unit and suspended
ceiling
T2A
The positioning must not create an obstacle that may lead
T10A
to an unequal distribution and/or return flow of the air.
T16A
The ceiling must be sufficiently even to allow simple
installation of the unit, with no risks.
The supporting structure must be able to bear the weight of
the unit and prevent deformation, failure or vibrations
during operation.
INSTALLATION PRECAUTIONS: When installing the
unit, check that no construction debris remains in the
ducts as this could cause damage to the unit.
