Connecting the PV generator using cable fi ttings
Connecting three or four strings to the inverter requires
the double assignment of one or both connection terminals
(see fi gure 6.5).
Figure 6.5: Connection of three PV strings
Connecting the PV generator using MC or Tyco plug
connectors
As an option, MC or Tyco plug connectors can be delivered with
the inverter. These can be used instead of the cable fi ttings that
were already installed upon delivery. These pre-installed cable
fi ttings must fi rst be removed before installing the appropriate
plug connectors.
Figure 6.6: Installation of Tyco sockets
The assembly of the Tyco and MC plug connectors is shown in
fi gure 6.7 and 6.8 respectively.

AT TENTION
To achieve protection class IP54, unused cable fi ttings must
be closed off by using the included blind caps.
ACTION
Unscrew the cable fi ttings until you can insert the cables.
Screw the ends of the cables into place in the connection
terminals labelled “PV+” and “PV-”. When doing this,
ensure that the polarity is correct. Tighten the cap of the
cable fi ttings.
Always disconnect the inverter from the PV gen-
erator by operating the DC main switch before
pulling the plug connector. Failure to observe this
may cause arcing, which can result in a hazard to
health and to the unit.
WARNING
ACTION
Unscrew the cable fi ttings from the cut-outs in the base
plate of the inverter.
Insert the Tyco or MC sockets from the outside through
the cut-outs and secure them from the inside using the
counter nuts (see fi gure 6.6).
