Net cooling capacity = gross cooling capacity minus the water pump heat against the internal evaporator pressure drop.
Electrical data notes (cont.)
• 30GZ units have a single power connection point (except 30GZ 170-245 which have two connection
points).
• 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.
• The Carrier 30GZ chillers are designed and built to ensure conformance with these 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:
• Generally the recommendations of IEC 364 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. The operating environment for the 30GZ chillers is specified below:
• Environment* - Environment as classified in EN 60 721:
- outdoor installation*
- ambient temperature range: -18°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
30GZ units are protected to IP44CW and fulfill this protection condition.
