Electrical data notes and operating conditions for 30XAV units
• 30XAV 0500 to 0700 units have a single power connection point located immediately
upstream of the main switch(es). Standard units 0800 to 1150, have two power
connection points located in the immediate upstream of the main switches.
• With the exception of size 0500 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 0600 and 0700 sizes. A
disconnect switch for each refrigeration circuit for 0500 and 0800 to 1150 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 30XV 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 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 networks (IEC 60364). In IT networks 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 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 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.
