Electrical data notes and operating conditions for 30XA units:
• 30XA 252-1002 units have a single power connection point; 30XA 1112, 1212,
1312, 1382, 1402 to 1702 units have two connection points.
• The control box includes the following standard features:
- One general disconnect switch per circuit
- Starter and motor protection devices for each compressor, the fan(s) and
the pump
- Control devices
Field connections:
• All connections to the system and the electrical installations must be in full
accordance with all applicable local codes.
• The Carrier 30XA 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 compo-
nents - part 1: General regulations) are specifically taken into account, when
designing the electrical equipment.
IMPORTANT:
• Generally the recommendations of IEC 60364 are accepted as compliance
with the requirements of the installation regulations.
• Conformance with EN 60204 is the best means of ensuring compliance with
the Machines Directive § 1.5.1.
Annex B of EN 60204-1 describes the electrical characteristics used for the
operation of the machines.
1. Environment* - Environment as classified in EN 60364 (corresponds to IEC
60364):
- Outdoor installation*
- Ambient temperature range: from -20 °C to +55 °C**
- Altitude less than or equal to 2000 m (for hydronic module, see
paragraph 4.7 in the IOM)
- Presence of hard solids, class AE3* (no significant dust present)
- Presence of corrosive and polluting substances, class AF1 (negligible)
- C ompetence of persons: BA4 (Persons wise); 30XA machines are not
intended to be installed in locations open to anyone, including people
with disabilities and children.

2. Compatibility for low-frequency conducted disturbances according to
IEC61000-2-2 and to class 2 levels per IEC61000-2-4 standard:
- Power supply frequency variation : +-2Hz
- Phase imbalance : 2%
- Total Voltage Harmonic Distortion (THDV) : 8 %
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 simplified connection on TN(s) networks (IEC 60364).
For IT networks provide a local earth and consult competent local organisations
to complete the electrical installation. Units delivered with speed drive
(options 28) are not compatible with IT network.
• Derived currents: If protection by monitoring of derived currents is necessary to
ensure the safety of the installation, the control of the cut-out value must take the
presence of leak currents into consideration that result from the use of optional
frequency converters in the unit. In particular, a type of enhanced immunity
protection and/or a value of at least 150 mA is recommended to control
differential protection devices.
• Capacitors that are integrated as part of the option 231 can generate electrical
disturbances in the installation the unit is connected to. Presence of these
capacitors must be considered during the electrical study prior to the start-up.
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.
* The required protection level for this class is IP43BW (according to reference
document IEC 60529). All 30XA units are protected to IP44CW and fulfil this
protection condition.
** The maximum ambiant temperature allowed for machines equipped with
option 231 is +40 °C
