Carrier 30RB-170R User Manual

5.13 - Comments on electrical data notes
• 30RB/30RBP 30RQ/30RQP units have a single power connection point located
immediately upstream of the main disconnect switch.
• The control box includes:
- A main disconnect switch,
- The start-up and motor protection devices for each compressor, the fans and
the pumps,
- The control devices.
• Field connections:
All connections to the system and the electrical installations must be in accordance
with all applicable codes.
• 30RB/30RBP 30RQ/30RQP units are designed and built to ensure conformance
with these codes. The recommendations of European standard EN 60204-1
(corresponding to IEC 60204-1) (Machine safety - Electrical machine components
- part 1: General regulations) are specically taken into account, when designing
the electrical equipment.
Notes
• Generally the recommendations of IEC 60364 are accepted as compliance with
the requirements of the installation regulation.
• Compliance with EN 60204-1 is the best means of ensuring compliance with the
requirements (§1.5.1) of the Machinery Directive.
• Annex B of standard EN 60204-1 species the electrical features used for the
operation of the units.
• Operating conditions of 30RB/30RBP 30RQ/30RQP units are described below:
1. Environment
(1)
The classication of the environment is specied in standard EN 60364:
- Outdoor installation
(1)
,
- Ambient temperature range: Minimum temperature -20°C to +48°C,
- Altitude: AC1 of 2000 m or less (for the hydraulic module, see the paragraph
"Electrical data for the hydraulic module"),
- Presence of solid foreign bodies: Class AE3 (no signicant dust present)
(1)
,
- Presence of corrosive and polluting substances, class AF1 (negligible),
- Competence of personnel: BA4 (trained personnel).
2. Compatibility for low-frequency conducted disturbances at class 2 levels as
per the IEC 61000-2-4 standard:
- Power supply frequency variation: +- 2Hz
- Phase imbalance: 2%
- Total Voltage Harmonic Distortion (THDV): 8%
3. The neutral (N) wire must not be connected directly to the unit (if necessary
use a transformer).
4. Overcurrent protection of the power supply conductors is not provided with
the unit.
5. The factory-tted disconnect switch(es)/circuit breaker(s) are of a type suitable
for power interruption in accordance with EN 60947-3 (corresponds to
IEC 60947-3).
6. The units are designed for connection to TN type networks (IEC 60364).
In IT networks, if noise lters are integrated into the variable frequency drive(s),
this will render the units unsuitable for their intended purpose. In addition,
the equipment characteristics in case of insulation failure are modied. Provide
a local earth; consult competent local organisations to complete the electrical
installation.
Machines 30RB/30RBP 30RQ/30RQP are designed for use in domestic / residential
and industrial environments: Machines that are not equipped with variable speed
drives comply with general standards.
- 61000-6-3: General standards - Standard emission for residential, commercial
and light industry,
- 61000-6-2: General standards - Immunity for industrial environments
Machines equipped with one or more variable frequency drives (RBP RQP,
options: 28, 116V, 116W) comply with standard EN61800 - 3 "Variable-speed
electrical power drive systems - Part 3: EMC requirements and specic test
methods" for the following classications: Use in rst and second
environments
(2)
.
- Category C2 applicable in the rst environment, on stationary devices
designed to be installed and commissioned by a professional.
Warning: In a residential environment, this product may cause radio
interference; in this case, additional mitigation measures could be required.
• Leakage currents: If protection by monitoring the leakage currents is necessary
to ensure the safety of the installation, the presence of additional leakage currents
introduced by the use of variable frequency drive(s) in the unit must be considered.
In particular, the reinforced immunity protection types and/or a control value not
lower than 150 mA are recommended when selecting di󰀨erential protective
devices.
Note: If particular aspects of an actual installation do not conform to the
conditions described above, or if there are other conditions which should
be considered, always contact your local representative.
(1) The required protection level for this class is IP43BW (according to reference
document IEC 60529). As all 30RB/30RBP 30RQ/30RQP units are class
IP44CW, they full this protection condition.
(2) - Example of installations included in the rst environment: Commercial and
residential buildings.
- Example of installations included in the second environment: Industrial areas,
technical facilities supplied by a specic transformer.
