5.9 - Comments on electrical data notes
• AQUACIAT
POWER
™ units have a single power connection point, located
immediately upstream of the main disconnect switch.
• The control box includes:
-
A main disconnect switch,
-
The start-up and motor protection devices for each compressor, the fans and
the pumps,
- The control devices.
• Field connections:
All connections to the system and the electrical installations must be in accordance
with all applicable codes.
• AQUACIAT
POWER
™ units are designed and built to ensure compliance with these
regulations. The recommendations of European standard EN 60204-1
(corresponding to IEC 60204-1) (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 regulation.
• Compliance with EN 60204-1 is the best means of ensuring compliance with the
requirements (§1.5.1) of the Machinery Directive.
•
Annex B of standard EN 60204-1 specifies the electrical features used for the
operation of the units.
• The operating conditions of AQUACIAT
POWER
™ units are described below:
1. Environment*
The classification of environment is specified in standard EN 60364:
-
Outdoor installation*,
-
Ambient temperature range: Minimum temperature -20°C to +48°C,
-
Altitude: AC1 of 2000 m or less (for the hydraulic module, see the paragraph
"Electrical data for the hydraulic module"),
-
Presence of solid foreign bodies: Class AE3 (no significant dust present)*,
-
Presence of corrosive and polluting substances, class AF1 (negligible),
- Competence of personnel: BA4 (trained personnel).
2. Compatibility for low-frequency conducted disturbances at class 2 levels as
per the IEC 61000-2-4 standard:
- Power supply frequency variation: +- 2Hz
- Phase imbalance: 2%
- Total Voltage Harmonic Distortion (THDV): 8%
3. The neutral (N) wire 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-fitted disconnect switch(es)/circuit breaker(s) are 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 type networks (IEC 60364).
In IT networks, if noise filters are integrated into the variable frequency drive(s),
this will render the units unsuitable for their intended purpose. In addition,
the equipment characteristics in case of insulation failure are modified. Provide
a local earth; consult competent local organisations to complete the electrical
installation.
AQUACIAT
POWER
™ machines are designed to use for use in domestic/residential
and industrial environments:
Machines that are not equipped with speed regulators comply with the standard
codes.
-
61000-6-3: General standards - Standard emission for residential, commercial
and light industry,
- 61000-6-2: General standards - Immunity for industrial environments
- Machines equipped with one or more variable frequency drives
(AQUACIAT
POWER
™, options: XtraFAN, all-season operation, high seasonal
performance (VSD/EC), variable-speed pumps) comply with the standard
EN61800 - 3 "Variable-speed power drive systems - Section 3:
EMC requirements and specific test methods" for the following classifications:
Use in the first and second environments**.
-
Category C2 applicable in the first environment, on stationary devices
designed to be installed and commissioned by a professional.
Warning: In a residential environment, this product may cause radio
interference in which case additional mitigation measures could be required.
• Leakage currents: if protection by monitoring the leakage currents is necessary
to ensure the safety of the installation, the presence of additional leakage currents
introduced by the use of variable frequency drive(s) in the unit must be considered.
In particular, reinforced immunity protection types and/or a control value not lower
than 150 mA are recommended when selecting differential protective devices.
