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
-

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.
