Transformerless central inverter

Temperature range

Temperature in the electrical operating area during installation and in
operation:
T = –20 °C to +50 °C Note:
|
As of T = +45 °C, the output is automatically reduced in devices
|
from the level of performance 350 kVA.
Maximum relative humidity:
95% (non-condensing)
|

Ventilation

Material damage due to blocked ventilation!
Foreign objects stored in the operating room may obstruct the ventilation
and result in material damage and loss of yield.
Keep central inverters, floors and air ducts free of foreign objects.
|
Keep the operating area dry, clean and free of foreign objects.
|
Keep air inlets and outlets of the central inverter and of the operating
|
area free of foreign objects.
Keep the operating area free of combustible or explosive materials and
|
aggressive, caustic or corrosive gases and substances.
Material damage due to inadequate ventilation!
If, owing to insufficient ventilation capacity or blocked air passageways,
individual components of the device are unable to achieve sufficient
cooling, these components may age prematurely. The components may be
irreparably damaged. The circulation of air is only possible if all safety
covers are fitted and the device is closed.
Fit all safety covers.
|
Do not operate the device except in its closed state.
|
Provide sufficient ventilation in the operating area.
|
Please note:
Heat input of the device: The efficiency characteristic curve
|
(see Technical Data Sheet of the device) shows the level of the device's
heat input at the individual operating points. E.g. at an output of
300 kVA and an efficiency level of 98%, there is a heat loss of 2%,
which corresponds to 6 kW. Then there is the addition of 1 kW heat,
which is delivered by the auxiliary power supply.
The cooler the environment of the central inverter, the greater its level
|
of efficiency and the longer its expected service life.
