2.1 Fixing the unit
The inverter must be firmly anchored with suitable fastening systems to a steady support able to bear the weight of the appliance. It
must be fixed with screws inserted in the holes provided on the edge of the plate, as shown in Figure 2.
The fastening system and the support to which the appliance is fixed must have a bearing capacity suitable for the weight of the
appliance, see Table 1.
Units can be installed side by side, but the minimum clearances must always be guaranteed, as shown in Figure 2. on the sides
where aeration outlets are located, to ensure correct air circulation as shown in Figure 2.
