Electrical data notes
• 30SZ/SZV* units have a single power connection point.
• The control box includes the following standard features:
- the start-up and motor protection devices for each compressor.
- the 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 30SZ/SZV units are designed and built to ensure con-formance
with these codes. The recommendations of European standard EN 60204-1
(corresponding to IEC 60204-1)-(machine safety - electrical machine compo-
nents - part 1: general regulations) are specifically taken into account, when
designing the electrical equipment.
Notes:
• Conformance with EN 60204-1 is the best means of ensuring compliance with
the Machines Directive § 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 30SZ/SZV units is specified below:
• Environment* - Environment as classified in EN 60634 § 3:
- ambient temperature range: +5°C to +40°C, class AA4*
- humidity range (non condensable)*:
50% rh at 40°C
90% rh at 20°C
- altitude:
£
2000 m
- indoor installation*
- presence of water, class AD2* (possibility of water drops)
- 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
- Competence of personnel, class BA4* (personnel trained in accordance
with IEC 60364)
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) is (are) of a type suitable for power
interruption in accordance with EN 60947-3 (corresponding to IEC 60947-3).
6. The units are designed for connection to TN networks (IEC 60364). For IT
networks 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 required protection level for this class is IP21B (according to reference
document IEC 60529). All 30SZ/SZV units are protected to IP23C and fulfil this
protection condition.
