Installing The Inverter; Electrical Connection - Kaco Powador 2500xi Operating Instructions Manual

–
If the inverter is built into a switching cabinet or similar,
provide forced ventilation to insure that heat is suffi ciently
dissipated.
– The heat sink may reach a max. temperature of 90 °C. There-
fore, mount the inverter only on walls made from heat-resist-
ant material.
–
Ensure that the wall has adequate load-bearing capacity
and use appropriate installation material.
–
In areas prone to fl ooding, be sure to install the inverter in
a suffi ciently elevated place.
–
Installation at eye level makes it easier to read the display.

Due to the high system voltage, the current that fl ows on
the DC side is lower than that fl owing on the AC side. If
the cable cross-sections are the same, losses on the AC-
side lead are, therefore, higher than those on the DC side.
For this reason and due to thermal factors, it makes sense
to position the inverter near the meter.

Installation Instructions Powador 2500xi / 3600xi / 4000xi / 4500xi / 5000xi_EN
An installation kit consisting of four anchors and four 70 mm
screws is shipped with the inverters. Check the composition
and condition of the wall before installation. If necessary,
use an installation kit other than the one shipped with the
inverter.
–
Drill the holes for the anchors at the selected instal-
lation position to match the cut-outs in the mounting
plate.
–
Place the anchors into the holes.
–
Use the screws to mount the mounting plate onto
the wall at the selected location. When doing so, be
sure that the arrow cut into the mounting plate points
upwards.
–
Mount the inverter on the mounting fi xture so that the
pegs in the heat sink rest in the notches.
–
Lock the safety catch. To do this, slide the upper end of
the safety catch towards the wall until the groove runs
parallel to the wall (see fi gure 6.2).

6.3 Electrical connection

General information
After the inverter has been installed in its fi xed location, the
electrical connection to the unit can be established.
The Powador may be installed only by trained
and authorised specialists.
