Requirements on the place of installation

· Mechanical bearing capacity

During installation please bear in mind that the solar inverter weighs 26 kg. The installation base must be firm and capable of continuously bearing the weight.

· Thermal interaction

The installation base must consist of flame-retardant material (e.g. no wood or plastic in the base; concrete and brickwork are suitable), as the heat sink emits tempe- ratures up to max. 85°C.

A minimum distance of 300 mm must be maintained above and below the cabinet, and 150 mm on right and left from other units, cabinets, ceilings, cable ducts etc..

The solar inverter must be installed verti- cally, so as not to hinder adequate free convection.

Several solar inverters must not be instal- led on top of each other, so as to prevent reciprocal heating.

If installing the solar inverter in a switch box, ensure adequate heat dissipation.

The ambient temperature must not fall below or exceed –25°C or +40°C.

The solar inverter should not be exposed to direct solar irradiation, so as to protect it from unnecessary external heating.

· Protection from damp and foreign bodies EN

The IP54 high protection class permits instal- lation both inside and in roofed outdoor areas, but the solar inverter must not be exposed to direct rain.

Make sure that the solar inverter cannot be exposed to foreign bodies (deposits of dust and dirt).
