Specifications
6
Notes:
• 19XR units have a single power connection point.
• The control box includes the following standard features:
- Starter and compressor motor protection devices, or
- protection and control elements only
• Field connections:
All connections to the system and the electrical installations must be in full accordance
with all applicable codes.
• The Carrier 19XR units are designed and built to ensure conformance with local codes.
The recommendations of European standard EN 60204-1 (corresponds to IEC 60201-
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 60364 are accepted as compliance with the
requirements of the installation directives. Conformance with EN 60204-1 is the best
means of ensuring compliance with the Machines Directive and § 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 19XR units is specified below:
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
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. 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) disconnect devices
of a type suitable for power interruption in accordance with EN 60947-3 (corresponds 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 protection level required to conform to this class is IP21B (according to reference
document IEC 60529). All 19XR units are protected to IP23C and fulfil this protection
condition.

Notes:
1. Oil sump heater only operates when the compressor is off.
2. Power to oil heater/controls must be on circuits that can provide continuous service when
the compressor is disconnected.
