CAUTION
Dry
The formation of condensation within a SolarMax inverter must be avoided: There
must be no puddles, damp masonry walls or similar sources of humidity in the vi-
cinity of the device. Plant rooms which are not effectively protected against water
or snow are not suitable as installation locations.
CAUTION
Dust-free
The inverter must be operated in a room with as a little dust as possible to prevent
avoidable accumulations of dust on the heat sinks and fans. Rooms with heavy
concentrations of dust (e.g., carpentries or metal construction shops) are not suit-
able installation locations.
The installation location must meet the requirements contained in the standard for
electromagnetic immunity for industrial environments (EN 61000-6-2) and for
emissions in industrial environments (EN 61000-6-4).
To ensure that the inverter is accessible for possible repair work the front side must
be at least 1 m away from the nearest object (wall, other inverters, etc.). Do not
install the inverter on a raised surface, platforms or consoles.
Do not install the inverter where the ambient air contains salts or ammonia.
NOTE
Due to possible noise we do not recommend installation in or near residential
rooms or workplaces.
Please remember that the inverter and any existing accessories give off heat during
operation which can contribute to a serious heating up of the ambient air if the plant
rooms are small or poorly ventilated. If the conditions in your plant room could lead
to an unacceptable heating of the ambient air (Tambient air > 50 °C) then the instal-
lation of an additional ventilation system is necessary. Our basic rule is always to
recommend that the ambient temperature be kept under 30 °C. Each inverter
needs 1500 m3of fresh air per hour.
The inverter’s heat sinks are actively cooled by internal fans. The cool, fresh air enters the
inverter from below, is drawn in by the fans and is blown upwards through the ventilation
screens out of the inverter.
For safety reasons the temperature of the heat sink is limited to 85 °C. At ambient
temperatures of more than 45 °C the heat sink temperature may reach 80 °C. If this hap-
pens, the maximum feed output is temporarily reduced and a corresponding status mes-
sage appears on the inverter’s display screen. But if the temperature still runs as high as
85 °C the inverter is shut down to prevent a thermal overload.
