*  Standard Eurovent conditions: Evaporator entering/leaving water temperature 12°C/7°C, condenser entering/leaving water temperature 30°C/35°C.

 

Nominal operating power input: unit power input (compressors, control) plus the capacity corresponding to the evaporator and condenser pressure drop (flow x drop/0.3).

**  Power input, compressors, at unit operating limits (saturated evaporating temperature (dew point) = 12°C, saturated condensing temperature (dew point) = 52°C 

(30HZ)/66°C (30HZV), and a nominal voltage of 400 V (data given on the unit name plate).

***  Maximum unit operating current at maximum unit power input.

†  Maximum instantaneous starting current (maximum operating current of the smallest compressor(s) + locked rotor current or reduced starting current of the largest 

compressor).

‡  Current and power inputs not included in the values above.

Notes for electrical data:

•  30HZ/HZV 043 to 225 units have a single power connection point; 30HZ/HZV 

250 to 280 units have two connection points.

•  The control box includes the following standard features:

 

- 

Starter and motor protection devices for each compressor

 

- 

Control devices

• 

Field connections:

 

All connections to the system and the electrical installations must be in full 

accordance with all applicable codes.

•  The Carrier 30HZ/HZV chillers are designed and built to ensure conformance 

with local 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.

IMPORTaNT:

•  Conformance with EN 60204-1 is the best means of ensuring compliance with the 

Machines Directive and § 1.5.1. Generally the recommendations of IEC 60364 

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 the 30HZ/HZV chillers is specified below:

 

a.  Environment* - Environment as classified in IEC 60364 § 3:

 

 

-  ambient temperature range: +5°C to +40°C, class AA4

 

 

-  humidity range (non-condensing)*: 50% relative humidity at 40°C,

 

 

 

90% relative humidity at 20°C

 

 

-  altitude: ≤ 2000 m

 

 

-  indoor installation*

 

 

-  presence of water: class AD2* (possibility of water droplets)

 

 

-  presence of hard solids, class AE2* (no significant dust present)

 

 

-  presence of corrosive and polluting substances, class AF1 (negligible)

 

 

-  vibration and shock, class AG2, AH2

 

b.  Competence of personnel, class BA4* (trained personnel - IEC 60364)

2.  Power supply frequency variation: ± 2 Hz.

3.  The neutral (N) conductor must not be connected directly to the unit (if 

necessary use a transformer).

4.  Over-current 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.

6.  The units are designed for connection to TN networks (IEC 60364). For IT net-

works the earth connection must not be at the network earth. Provide a local earth, 

consult competent local organisations to complete the electrical installation.

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 protection level required to conform to this class is IP21B (according to 

reference document IEC 60529). All 30HZ/HZV units are protected to IP23C 

and fulfil this protection condition.
