Shock and Vibration
Do not drop the inverter or expose to sudden shock. Do not install the inverter in an
area where it is likely to be exposed to constant vibration.
Mechanical strength to DIN IEC 68-2-6
Deflection: 0.075 mm (10 ... 58 Hz)
Acceleration: 9.8 m/s 2 (> 58 ... 500 Hz)
Electromagnetic Radiation
Do not install the inverter near sources of electromagnetic radiation.
Atmospheric Pollution
Do not install the inverter in an environment, which contains atmospheric pollutants
such as dust, corrosive gases, etc.
Water
Take care to site the inverter away from potential water hazards, e.g. do not install
the inverter beneath pipes that are subject to condensation. Avoid installing the
inverter where excessive humidity and condensation may occur.
Installation and cooling
CAUTION
The inverters MUST NOT be mounted horizontally.
The inverters can be mounted without any clearance at either side.
Allow 100 mm clearance above and below the inverter. Make sure that the cooling
vents in the inverter are positioned correctly to allow free movement of air.
