Electrical data notes and operating conditions for 30XAS units:
• 30XAS 242-482 units have a single power connection point located immediately
upstream of the main disconnect switch.
• The control box includes the following standard features:
- One general disconnect switch
- Starter and motor protection devices for the 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 30XAS units are designed and built to ensure conformance with
these codes. The recommendations of European standard EN 60 204-1
(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 directives.
• Conformance with EN 60 204 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 60 364 (corresponds to IEC
60364) :
- Outdoor installation*
- Ambient temperature range: from -20 °C to +55 °C**
- Altitude less than or equal to 2000 m (for hydraulic module, see paragraph 4.3
in the IOM)
- Presence of hard solids, class AE3 (no significant dust present)*
- Presence of corrosive and polluting substances, class AF1 (negligible)
- Competence of persons: BA4 (Persons wise); 30XAS machines are not intended
to be installed in locations open to anyone, including people with disabilities
and children.

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 simplified connection on TN(s) networks (IEC
60364). For IT networks derived currents may interfere with network monitoring
elements, and it is recommended to create an IT type divider for the system
units that require this and/or a TN type divider for Carrier units. Please consult
the appropriate local organisations to define the monitoring and protection
elements and carry out the electrical installation. Units delivered with speed
drive (options 28) are not compatible with IT network.
7. 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 frequency converters in the unit. 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 30XAS units are protected to IP44CW and fulfil this
protection condition.
** The maximum ambiant temperature allowed for machines equipped with option
231 is +40°C.
