Electrical data notes and operating conditions for 30XB units:
• 30XB(E/P) 250 to 1000 units have a single power connection point; 30XB(E/P)
1100 to 1700 units have two connection points.
• The control box includes the following standard features:
- One general disconnect switch per circuit
- Starter and motor protection devices for each compressor, the fan(s) and the
pump
- 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 30XB(E/P) units are designed and built to ensure conformance with
these 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:
• Generally the recommendations of IEC 60364 are accepted as compliance with
the requirements of the installation regulations.
• Conformance with EN 60204 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.
Environment* . Environment as classified in EN 60364 (corresponds to IEC
60364):
- Outdoor installation*
- Ambient temperature range: from -20°C to +55°C**
- Altitude less than or equal to 2000 m (for hydraulic module, see paragraph 4.7
in the IOM)
-
Presence of hard solids, class AE3 (no significant dust present)*
- Presence of corrosive and polluting substances, class AF1 (negligible)
- Units shall not be located in places open to all persons, which can includ
children.
2. Compatibility for low-frequency conducted disturbances according to
IEC61000-2-2 and to class 2 levels per IEC61000-2-4 standard:
- Power supply frequency variation : +-2Hz
- Phase imbalance : 2%
- Total Voltage Harmonic Distortion (THDV) : 8% **
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)/circuit breaker(s) is (are) of a type
suitable for power interruption in accordance with EN 60947-3
(corresponds to IEC 60947-3).
6.
The units are designed for simplified connection on TN(s) networks (IEC
60364). For IT networks provide a local earth and consult competent local
organisations to complete the electrical installation. Units delivered with
variable frequency drive(s) (options 28 or 17, and 30XBE range) are not
compatible with IT network. 30XB units are designed to use for domestic /
residential and industrial environments:
Machines that are not equipped with variable frequency drive(s) are in
accordance with the codes :
- 61000-6-3: Generic standards - Standard emission for residential, commercial
and light industry.
- 61000-6-2: Generic standards - Immunity for industrial environments.
Machines that are equipped with variable frequency drive(s) (options 28 or
17, and 30XBE range) are in accordance with the codes
- 61000-6-4: Generic standards - Emission standard for industrial environments.
- 61000-6-2: Generic standards - Immunity for industrial environments.
• Leakage currents: If protection by monitoring the leakage currents is necessary
to ensure the safety of the installation, the presence of circuitry with DC component
as well as additional leakage currents introduced by the use of variable frequency
drive(s) in the unit must be considered (options 28, 17 & 30XBE range). In
particular these protection devices shall be
- suitable for protection of circuitry with AC and DC components
- of reinforced immunity types and have a threshold not lower than 150mA.
• Capacitors that are integrated as part of the option 231 can generate electrical
disturbances in the installation the unit is connected to. Presence of these
capacitors must be considered during the electrical study prior to the start-up.
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 60529). All 30XB(E/P) units are protected to IP44CW and fulfil
this protection condition.
** These limits are modified for machines equipped with option/QM 231:
Maximum ambiant temperature : 45°C
Total Voltage harmonic distortion : 3%
