LOCATION

This is a class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to
take adequate measures.

The inverter units should be installed in a location that meets the
following requirements:

1

The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.

2

The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (Refer to

figure 1

 and choose one of the possibilities).

In case of an installation site where only the sides A+B have
obstacles, the wall heights have no influence on any indicated
service space dimensions.
