laws. INGECON SUN PowerMax units have CE marking by reason of their compliance with the following directives:
• Low Voltage Directive 2006/95/EC
• Electromagnetic Compatibility Directive 2004/108/EC
To comply with each directive, compliance with the parts applicable to our units of the appropriate harmonised stand-
ards is sufficient.
Low Voltage Directive
INGECON SUN PowerMax units comply with this directive by means of compliance with the applicable parts of harmo-
nised standard EN 50178 Electronic equipment for use in power installations.
Electromagnetic Compatibility Directive
INGECON SUN PowerMax units comply with this directive by means of compliance with the applicable parts of
harmonised standards:
• EN 61000-6-2 Electromagnetic Compatibility. Part 6-2: Generic standards - Immunity for industrial
environments.
• EN 61000-6-4 Electromagnetic Compatibility. Part 6-4: Generic standards - Emission for industrial
environments.
Compliance with these standards calls for compliance with limits and procedures in other standards of the same
series.
2. System description
2.1. Location
INGECON SUN PowerMax units need to be installed in environments with specific characteristics.
Guidelines are provided in this section for choosing a suitable environment and adapting the unit to it properly.
2.1.1. Environment
Place the units in a place which is accessible for installation and maintenance work and which
permits use of the keyboard and the reading of the front indicator LEDs.
The air vents and part of the cabinet close to them can reach 85 °C. Do not place any material nearby
which is sensitive high air temperatures.
Avoid corrosive environments that may affect the proper operation of the inverter.

AAV2000IKI01 15
Installation manual Ingeteam
Never place any object on top of the unit.
2.1.2. IP rating
INGECON SUN PowerMax units have a IP20 level of protection against external agents.
IP20 means that the unit is fully protected against the ingress of dust and also against water streams from any direc-
tion as defined for this level of protection in standard IEC60529.
INGECON SUN PowerMax units should therefore be installed in an enclosed, covered location.
The environment in which they are assembled should always be dry and free of dust.
Not suitable for outdoor installation.
2.1.3. Ambient temperature
These units are designed to operate in a temperature range from -20 °C to 65 °C.
2.1.4. Atmospheric conditions
The ambient air must be clean and relative humidity must not exceed 50% at over 40 °C. Higher levels of relative
humidity, up to 95%, can be tolerated at below 30 °C.
It should be borne in mind that moderate condensation may occasionally occur as a consequence of temperature
variations. For this reason, apart from the unit's own protection, vigilance of these units is necessary once they have
been started up on sites where the conditions described above are not expected to be present.
In the event of condensation, never apply voltage to the unit.
2.1.5. Contamination class
The pollution class for which the units have been designed is grade 3.
Suitable measures should be taken to provide dust-free air of sufficient quality in the vicinity of the inverter.
2.1.6. Acoustic contamination
When on, the inverter generates a buzzing sound.
Do not place it in an occupied room, or on light supports which might amplify this buzz. The mounting surface must
be firm and appropriate for the weight of the unit.
2.1.7. Ventilation
A minimum space of 20 cm must be maintained on both sides and in back of the unit to allow the free circulation of
air through the circulation vents. A minimum distance of 1 meter should be left in the front of the unit in order to gain
access to the unit through the doors.
INGECON SUN PowerMax units have cooling fans on top of each electronics block. These fans start
up for a few seconds each time the inverter is connected to the mains and is about to inject power.
This procedure makes it possible to easily check proper operation.
Fans require different air flow for cooling electronics, depending on the number of electronics units and the number
of unit cabinets. Always provide for each unit the flow values listed in the following table:
Model Airflow (m³/h)
250 M220 Indoor, 315 M275 Indoor, 365 M320 Indoor, 400 M345
Indoor, 420 M360 Indoor 2670
375 M220 Indoor, 500 M275 Indoor, 550 M320 Indoor, 600 M345

500 M220 Indoor, 625 M275 Indoor, 730 M320 Indoor, 800 M345
Indoor, 840 M360 Indoor 5340
Acceptable pressure loss is 34 Pa and air inlet velocity less than 3 m/s.
Do not place any object on top of the unit.
Avoid dropping particles that could enter the unit through air vents.
Facilitate the flow of air entering through the front ventilation grids, and the exhaust air through the
top grids.
If the unit is installed inside a cabin, a plenum will have to be installed to ensure the ventilation of the unit as shown
in the figure below.

AAV2000IKI01 17
Installation manual Ingeteam
The plenum must be common to all the modules as shown in the previous figure. In order to avoid unwanted air circu-
lation through the equipment, do not use individual plenums for each module, since this might affect their proper
operation.

AAV2000IKI01

Installation manualIngeteam
2.1.8. Support surface and fastening
Due to the INGECON SUN PowerMax unit’s heavy weight, the ground on which it rests should be firm
and completely horizontal and level.
Access to the AC feed varies depending on whether the model is NAC or not. In NAC models, each feed is made from
the base of each of the modules. In all other models, however, all the modules are powered through the base of the
AC module, which is the one on the right.
If the unit sits on a lower void for cabling, the base should rest on firm ground as much as possible without causing
mechanical stresses to the structure. Below you will see minimum supports for each unit (in millimetres).

2.3. Characteristics of the electrical installation
INGECON SUN PowerMax units are designed for connection to a dedicated network with an IT-type neutral connec-
tion scheme.
An IT scheme has no directly grounded feed point.
In this system, the resulting intensity of a first phase against mass or phase against ground fault is sufficiently low as
to not cause the appearance of dangerous contact voltages.
2.4. EMC requirements
The INGECON SUN PowerMax units are equipped with the necessary filtering elements to comply with EMC require-
ments for industrial applications in order to prevent disturbances in other equipment outside the installation.
All INGECON SUN PowerMax units are connected to the grid through a low to medium voltage transformer with a
Star-Delta configuration. This transformer gives the unit galvanic isolation that affects its good performance in terms
of noise emission. This is why:
Any auxiliary element must be connected to the low voltage network powering the INGECON SUN
PowerMax units via a galvanic isolation transformer.
