Electrical data notes and operating conditions:
• 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 start-up 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.
• 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.
• The operating conditions for the units are specified below:
1. Environment* - Environment as classified in EN 60721 (equivalent to
CEI60721):
- Indoor installation,
- ambient temperature range: +5°C for the temperature minimum to +40°C,
class 4K4H,
- humidity range (non-condensing)*:
- 50% relative humidity at 40°C
- 90% relative humidity at 20°C
- altitude: ≤ 2000 m (see note for table 4.5 in the IOM)
- 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-fitted 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. Units delivered with
speed drive (option 116J and 270J) are not compatible with IT network.
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 existing 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
IPX1B (according to reference document IEC 60529). All 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.
