Electrical data notes and operating conditions:
• BW10 units have a single power connection point, located immediately upstream
of the main disconnect switch.
• The control box includes the following standard features:
- a main disconnect switch,
- 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 BW10 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 conditions for the units are 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 (see note for table 4.6 - Electrical data, hydronic module)
- indoor installation*
- 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)
- 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 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.
7. Derived currents: If protection by monitoring of derived currents is necessary to
ensure the safety of the installation, the control of the cut-out value must take the
presence of leak currents into consideration that result from the use of frequency
converters in the unit. A value of at least 150 mA is recommended to control
differential protection devices.
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 Danfoss representative.
* The protection level of the control boxes required to conform to this class is IPX1B
(according to reference document IEC 60529). All BW10 units fulfil this protection
condition.
Units equipped with front casing panel meet class IP23. If the casing panel has
been removed, access to energised components is protected to level IPXXB.

Evaporator
Entering water temperature at start-up °C 7.5* 27
Leaving water temperature during operation °C 5** 20

* For entering water temperatures below 7.5°C at start-up, contact Danfoss.
** If the leaving water temperature is below 5°C, a frost protection solution must
be used. Please refer to option 6 for evaporator leaving water low-temperature
applications (< 5°C).
*** For applications with a condenser entering air temperature below 15°C the use of
a three-way valve is recommended. This three-way valve can be controlled by the
0-10 V analogue output of the control system.
**** For a water flow rate that corresponds to a maximum water-side temperature
difference of 5 K.
