2. System description
2.1. Location
These units must 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, the display and the reading of the front indicator LEDs.
A minimum space of 40 in (1 m) must be maintained on both sides and in front and behind the unit
to allow the free circulation of air through the circulation vents.
The air vents and part of the cabinet close to them can reach 185 °F (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.
Never place any object on top of the unit.
2.1.2. Protection class
These units meet NEMA type 3R degree of protection against external agents.
They are therefore designed to be suitable for outdoor location.
2.1.3. Ambient temperature
These units are designed to operate in a temperature range from -4 °F (-20 °C) to 149 °F (65 °C). Nominal power
may be input at up to 122 °F (50° C). Above this temperature the unit limits input power in order to cool the internal
temperature of the electronics.

2.1.4. Atmospheric conditions
The ambient air must be clean and relative humidity must not exceed 50% at over 104 °F (40 °C). Higher levels of
relative humidity, up to 95%, can be tolerated at below 86 °F (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
These units intake air through the sides of the housing and expel it from the front and back.
A minimum obstacle-free space of 40 in (1 m) must be maintained on both sides as well as in front of and behind the
unit to allow the free circulation of air.
These units are fitted with two cooling fans on the top of the cabinet. 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.
The fans require an adequate flow of clean, dust-free air for proper operation.
Do not place any object on top of the unit.

2.1.8. Environmental characteristics
The environmental conditions for operation are:
Ambient conditions
Minimum temperature (1) -4 °F (-20 °C)
Minimum surrounding air temperature (1) -4 °F (-20 °C)
Minimum surrounding air temperature 149 °F (65 °C)
Temperature at which power limiting commences 122 °F (50 °C)
Maximum relative humidity without condensation 95%
(1) Units including a heating element kit may be installed in locations with a minimum temperature of -13 °F (-25 °C).
For further information see Chapter “2.4. Location of the components”.
2.2. Characteristics of the electrical installation
These units are designed to be connected to the low voltage public grid.
2.3. EMC requirements
These units are equipped with the necessary filtering elements to comply with EMC requirements for industrial appli-
cations in order to prevent disturbances in other equipment outside the installation.
2.4. Location of the components
