2 - SAFETY CONSIDERATIONS
NOTE: Before any intervention on the unit, cut the main power
supply to the unit and any accessories.
2.1 - General points
The installation, commissioning and maintenance operations of
the various components of the system (unit, control system, hot
water, cold water, ventilation networks) can be dangerous if certain
factors specific to the installation are not considered such as the
presence of mains voltage and the presence of hot or cold water
in the air treatment equipment. Only specially trained and qualified
installers and technicians, having received in-depth training on
the product concerned, are authorized to install, commission and
maintain this equipment.
During any intervention, all the recommendations and instructions
which are mentioned in the maintenance manuals, on the labels
or in the instructions accompanying the entire equipment, as well
as all the other safety instructions applicable should be applied.
Definition of the pictograms used:
- Electrical danger: Fig. 1
- Be careful with your hands: Fig. 2
- General danger: Fig. 3
Follow all the safety regulations and codes in force. Wear safety
glasses and protective gloves. Handle the equipment with care
during handling and installation operations.
2.2 - Protection against electrocution
Only personnel qualified to perform electrical and maintenance
work may make electrical connections. It is especially mandatory
to cut all the power supplies to the unit before any intervention.
Cut the main power supply using the disconnecting device (not
supplied by Carrier).
IMPORTANT: The components constituting the various
control systems provided, include electronic items. As such,
they can generate electromagnetic disturbances or be
disrupted if they are not installed or operated in accordance
with the instructions herein. The components constituting
these control systems are in accordance with the requirements
for electromagnetic compatibility for residential, commercial
and light industry. They are also in accordance with the low
voltage guidelines.
When the product is delivered without Carrier regulator, verification
of EMC compliance is the responsibility of the integrator.
2.3 - General recommendations for installation
MPORTANT: The regulators must have an upstream
disconnecting device (double pole circuit breaker, for
instance). In case of necessity, an accessible emergency stop
device (lightning protection switch, for instance) must enable
switching off of all the devices. The installation must be
equipped with a device to protect against earth faults. The
disconnect device must simultaneously disconnect the two
poles (phase and neutral), and have a distance of at least 3
mm between the contacts, in compliance with the installation
instructions. The mains power cable must have 3 conductors
(blue, brown, green/yellow) and its cross section and type
must comply with the specifications set out by the applicable
EN or IEC standard. Refer to the selection sheet or the name
plate to determine the maximum input current. These devices
are not supplied by Carrier.
In general, the following rules must be observed:
Upstream protection against surges
Unit without electric battery
Unit with electric battery
12
- The devices must include upstream protection against current
leakage to earth (GFCI circuit breaker not supplied by
Carrier). Caution, the current leakage from the motor of the
unit is 0.27 mA with operating voltage 230 V AC.
- Clear marking must be done on the disconnecting device in
order to correctly identify the devices connected to it.
- Cabling for components constituting the various control
systems and the communication bus must be done in
accordance with the rules of the art by professional installers.
- The supply cable must be provided with double insulation
and held by the anti-traction jumper provided for this purpose,
or the cable clamp supplied with the Carrier digital controller.
The supply cable must be maintained with the double
insulation.
- The components constituting these various control systems
must be installed in an environment in accordance with their
protection index (PI).
- The maximum pollution level is normally polluting (level 2)
and the category of installation II.
- Low voltage cabling (Communication Bus) must be physically
separated from the power cabling.
- In order to avoid interference with the connecting cables:
• Separate the low voltage cables from the power cables,
avoid using the same cable route (maximum 300 mm
common with the 230 V AC, 30 A cable).
• Do not pass the low voltage cables into power cable loops.
• Do not connect heavy inductive loads to the same power
source (circuit breaker) used to supply the regulator
equipment or power modules.
• Use the screened type of cable recommended by Carrier
and maintain the cables connected to the regulators and
power modules.
2.4 - Recommendation regarding the regulation
IMPORTANT: It is not allowed to connect several 42GR ATM
to the same control element (wall-mounted thermostat, NTC
electronic regulator, etc...)
