Electrical data notes:
• BW05 020-300 units have a single power connection point.
• The control box includes the following standard features:
- the starter and motor protection devices for each compressor and the pumps
- 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 BW05 units are designed and built to ensure conformance with these codes.
The recommendations of European standard EN 60204-1 (machine safety -
electrical machine components - part 1: general regulations - corresponds to IEC
60204-1) are specifically taken into account, when designing the electrical unit
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 § 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 BW05 brine water heat pump 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. 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 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 representative.
* The protection level of the control boxes required to conform to this class is
IP21B (according to reference document IEC 60529). All BW05 units with correctly
installed casing panels fulfil this protection condition.
