Electrical data notes for AQUACIAT
POWER
ILD ST/ LD HE units:
• The AQUACIAT POWER ILD ST / ILD HE units only have a single power connection
point located immediately upstream of the main disconnect switch.
• Control box includes:
-
Main disconnect switch,
-
Start-up and motor protection devices for each compressor, fans and pumps,
-
Control devices.
• Field connections:
All connections to the system and the electrical installations must be in accordance
with all applicable codes.
• The AQUACIAT
POWER
ILD ST / ILD HE units are designed and manufactured
to ensure that these regulations can be observed. 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.
Notes
• Generally the recommendations of IEC 60364 are accepted as compliance
with the requirements of the installation regulation.
• Conformance with EN 60204-1 is the best means of ensuring compliance
(§1.5.1) with the Machinery Directive.
Appendix B of standard EN 60204-1 specifies the electrical features used for
the operation of the machines.
• The operating conditions for AQUACIAT POWER ILD ST / ILD HE units are described
below:
1. Environment
(1)
The classification of environment is specified in standard EN 60364:
- Outdoor installation (1) ,
- Ambient temperature range: minimum temperature -20°C to +48°C (2) ,
- Altitude: AC1 of 2000 m or less (for the hydronic module, see the
paragraph "Electrical data notes for the hydronic module"),
- Presence of hard solid: Class AE3 (no significant dust present) (1) ,
- Presence of corrosive and polluting substances, class AF1 (negligible),
- Competence of persons: BA4 (Persons wise).
2. Compatibility for low-frequency conducted disturbances according to class
2 levels per IEC61000-2-4 standard:
- Power supply frequency variation: +-2Hz
- Phase imbalance : 2%
- Total Voltage Harmonic Distortion (THDV) : 8%
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 units are designed for connection to TN networks (IEC 60364). In IT
networks, if noise filters are integrated into the variable frequency drive(s),
this will render the machines unsuitable for their intended purpose. In
addition, the short-circuit holding current characteristics are modified. Provide
a local earth, consult competent local organisations to complete the electrical
installation.
AQUACIAT POWER ILD ST / HE machines are designed to be used in domestic/
residential and industrial environments:
Machines that are not equipped with variable speed drives comply with the
standard regulations.
- 61000-6-3: General standards - Standard emission for residential,
commercial and light industry,
- 61000-6-2: General standards - Immunity for industrial environments.
Machines that are equipped with variable frequency drive(s) (AQUACIAT POWER
ILD ST, options: Winter operation down to -20°C, HP variable-speed single
or dual pump, hydraulic module) comply with the standard EN61800 - 3
"Adjustable speed electrical power drive systems - Part 3: EMC requirements
and specific test methods" for the following classifications:
Use in the first and second environments (3) .
- Category C2 applicable in the first environment, to 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, the reinforced immunity protection types and/or a control value
not lower than 150 mA are recommended when selecting differential protective
devices.
• Capacitors integrated into the Power factor correction option may generate
electrical disturbances on the system to which the unit is connected. Presence
of these capacitors must be considered during the electrical study prior to the
start-up.
Note: If particular aspects of an actual system do not conform to the
conditions described above, or if there are other conditions which should
be considered, always contact your manufacturer.
(1) The required protection level for this class is IP43BW (according to reference
document IEC 60529). All AQUACIAT POWER ILD ST / ILD HE units are classified
as IP44CW, and fulfil this protection condition.
(2) The maximum allowable ambient temperature for machines equipped with
the Power factor correction option is +40°C
(3) - Example of installations of the first environment: Commercial and residential
buildings.
- Example of installations of the second environment: industrial zones,
technical premises powered from a dedicated transformer.
