•
30XAV-ZE 0401 to 0551 units have a single power connection point located
immediately upstream of the main switch(es). Standard units 0651 to 0901,
have two power connection points located in the immediate upstream of the
main switches.
•
With the exception of size 0401 and the units that are equipped with 81 and
70D options, anti short-circuits device is not provided as standard. It must
be installed at the facility in accordance with the instructions given in this
document.
•
The compressor and condenser fan motors are controlled and protected by
variable frequency drives installed on the machine frame.
•
The electrical control box contains:
-
A main disconnect switch for the entire machine for 0501 and 0551 sizes.
A disconnect switch for each refrigeration circuit for 0401 and 0651 to
0901 sizes.
-
All or part of the protection equipment against short-circuits for the
circuits inside the machine
*
-
Switch gear and protection for heaters and hydraulic pumps
-
Control devices.
• field connections:
•
All connections to the system and the electrical installations must be in
accordance with all applicable codes.
•
The Carrier 30XAV-ZE units are designed and built to ensure conformance
with these codes. The recommendations of European standard EN 60204-1
(corresponds to IEC 60204-1) (machine safety - electrical machine
components - part 1: General regulations) are specifically taken into
account, when designing the electrical equipment**.
• Appendix B of standard EN 60204-1 specifies the electrical characteristics
used for the operation of the machines. Those specified below are applied
to 30XAV-ZE units in addition to other information given in this document:
1.
Physical environment***; The classification of the environment is specified in
standard EN 60721 (equivalent to IEC 60721):
-
Outdoor installation
-
Ambient temperature range: Minimum temperature -20 °C up to +48 °C.
-
Altitude: Lower than or equal to 2000 m
-
Presence of hard solid: Class 4S2 (no significant dust present)
-
Presence of corrosive and polluting substances, class 4C2 (negligible)
2. Power supply frequency variation: ± 2 Hz
3. The neutral (N) line 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 installed disconnect switch(es)/circuit breaker(s) is (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 systems (IEC 60364). In
IT systems the use of noise filters integrated into the variable frequency
drive(s) makes machine use unsuitable. In addition, the short-circuit holding
current characteristics are modified. Provide a local earth, consult
competent local organisations to complete the electrical installation.
7. Electromagnetic environment: Classification of the electromagnetic
environment is described in standard EN 61800-3 (corresponds to
IEC 61800-3):
- Immunity to external interference defined by the second environment****
- Interference emission as defined in category C3
†
•
The harmonic currents generated by the variable frequency drives
integrated in the 30XAV-ZE unit are a source of interference. An analysis
may be required to verify if these interferences exceed the compatibility
limits of the other devices connected to the same power supply network.
The compatibility levels inside an electrical installation, that must be met at
the in-plant coupling point (IPC) to which other loads are connected are
described in standard 61000-2-4.
•
Two characteristics are required for this analysis:
-
The short-circuit ratio (Rsce) of the installation calculated at the in-plant
coupling point (IPC).
-
The total harmonic current distortion rate (THDI), calculated for the
machine at maximum capacity.
•
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 drives in the
unit must be considered. In particular these protection devices shall be of
reinforced immunity types and have a threshold not lower than 150 mA.
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 carrier
representative.
* Depending on the size or options selected for the machine
** Generally the recommendations of IEC 60364 are accepted as compliance
with the requirements of the installation directives. Conformance with
EN 60204-1 is the best means of ensuring compliance with the Machinery
Directive.
*** The required protection level for this class is IP43BW (according to
reference document IEC 60529). All 30XAV-ZE units are IP44CW and fulfil
this protection condition.
**** Example of installations of the second environment: Industrial zones,
technical locations supplied from a dedicated transformer
† Category C3 is suitable for use in an industrial environment and is not
designed for use in a public low-voltage system that supplies residential
locations. As an option, conformity with category C2 permits this type of
installation.
