The voltage of the PV array must be measured
before connecting the DC leads to the inverter
terminals. The DC voltage must not exceed the
maximum generator voltage of the inverter. Con-
necting to a higher voltage will destroy the unit.
The PV generator can be connected in the following ways:
– Screw terminals (through cable fi ttings)
– Tyco plug connectors
– MC plug connectors
The cable fi ttings are already installed upon delivery. As an
option, Tyco and MC plug connectors can be delivered with
the inverter.
Connecting the PV generator using cable fi ttings
AT T EN TI O N
To achieve protection rating IP54, unused cable fi ttings
must be closed off using the included blind caps.
AC T I O N
To do this, unscrew the cable fi ttings until you can insert the
cables through the fi tting, then 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 tting.
Connecting the PV generator using MC
or Tyco plug connectors (optional)
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.

Always disconnect the inverter from the PV gen-
erator by operating the integrated DC disconnect
before pulling out the plug connector. Failure to
observe this may cause arcing, which can result in
a hazard to health and to the unit.
AC TI ON
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
black plastic nuts.
The assembly of the Tyco and MC plug connectors is shown in
fi gure 5.7 and fi gure 5.8 respectively.
