4.3 - Short-circuit stability current for all units

Short-circuit stability current for all units using the TN system (earthing system type): 50 kA (conditional system short-circuit current
Icc/Icf at the unit connection point as rms value).
The unit is equipped with protection fuses located in the control box immediately downstream from the unit connection point.

Electrical data notes and operating conditions, 61XWH units
• 61XWH 3 to 7 units have a single power connection point located immediately
upstream of the main disconnect switch.
61XWH 10 to 17 units have two connection points located immediately upstream
of the main disconnect switches.
• The control box includes the following standard features:
- One main disconnect switch per circuit
- Starter and motor protection devices for each compressor
- Anti-short cycle protection devices
- Control devices
• Field connections: All connections to the system and the electrical installations
must be in full accordance with all applicable codes.
• The unit is 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.
• Compliance of the installation to 1999/92/CE directive on minimum requirements for
improving the safety and health protection of workers potentially at risk from explosive
atmospheres : The electrical equipment is not designed for compliance to
2014/34/EU directive for equipment and protective systems intended for use in potentially
explosive atmospheres. The compliance of the building installation with article 3 Prevention
of and protection against explosions shall be achieved by all necessary measures in
the installation for prevention of the formation of explosive atmospheres
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.
• Annex B of EN 60204 1 describes the electrical characteristics used for the
operation of the machines.

The operating environment for the units is specified below:
1. Environment
as classified in EN 60721 (corresponds to IEC 60721):
(1)
- indoor installation
- ambient temperature range: minimum temperature +5°C to +42°C, class AA4
- altitude: lower than or equal to 2000 m
- presence of water: class AD2 (possibility of water droplets)
- presence of hard solids, class 4S2 (no significant dust present)
- presence of corrosive and polluting substances, class 4C2 (negligible)
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)/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 unit is 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.
(1) The required protection level for this class is IPX1B (according to reference
standard IEC 60529). The unit fulfils this protection condition. In general the
casings fulfil class IPX3B
