** Maximum unit operating conditions (saturated suction temperature (R-22) or a suction dew point temperature (R-407C) of 10°C, saturated discharge temperature (R-
22) or discharge dew point temperature of 68.3°C.
*** ICF = maximum instantaneous current during starting, equal to the current value of the last compressor to start, plus the sum of the maximum currents of the other
compressors and fans ooperating.
Electrical data notes:
•
The units have a single power connection point.
•
A separate power source (230 V, 1 ph, 50 Hz) that does not exceed the main switch
capacity is required to power the compressor crankcase heater circuit. This source
must be supplied from a transformer. It must not be supplied from a phase + neutral
supply (for ground + neutral systems).
•
The control box includes the following standard features:
-
Starter and motor protection devices for each compressor and the fan(s)
-
Control devices
•
Field connections:
All connections to the system and the electrical installations must be in full
accordance with all applicable local codes.
•
These Carrier units are designed and built to ensure conformance with local codes.
The recommendations of European standard EN 60 204-1 (machine safety - electrical
machine components - part 1: general regulations) are specifically taken into account,
when designing the electrical equipment.
NOTES:
•
Conformance with EN 60 204 is the best means of ensuring compliance with the
Machines Directive § 1.5.1. Generally the recommendations of IEC 364 are accepted
as compliance with the requirements of the installation directives.
•
Annex B of EN 60204-1 describes the electrical characteristics used for the operation of
the machines.

1. The operating environment for these units is specified below:
•
Environment* - Environment as classified in EN 60 721:
-
outdoor installation*
-
ambient temperature range: -25°C to +46°C, class 4K4H*
-
altitude: < 2000 m*
-
presence of hard solids, class 4S2 (no significant dust present)
-
presence of corrosive and polluting substances, class 4C2 (negligible)
-
vibration and shock, class 4M2
•
Competence of personnel, class BA4* (trained personnel - IEC 364)
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 optional factory-installed circuit breaker is of type "a" (EN 60 204-1 § 5.3.2).
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 529). All units are protected to IP44CW and fulfill this protection
condition.
