−
Carefully lift the enclosure and slide it down over the 2 fixation bolts until it is
supported by the 2 fixation plates. Screw the 2 bolts to ensure a good fixation of
the inverter. Then the lifting tool can be disengaged.
−
By means of a lower end fixation screw (not provided) the enclosure can be
pushed against the rear support at the bottom also (see
Figure 25: Lower end fixation
For additional units, the same procedure has to be followed.
5.5 Inverter noise level
ESI-S produce a certain level of noise when they operate. The noise level depends on the
operating conditions of the unit and on the rating of the inverter. These values should
be taken into account when choosing a location for the inverter.
