9 Installation Instructions Powador 01xi
PV generator connection by means of screwed
cable gland fittings
Connecting three or four strings to the inverter requires
double allocation of one or, respectively two terminals
(see Figure 5.4).
Figure 5.4: Connection of three PV strings
PV generator connection by means of multi-contact
or Tyco plug-type connectors
MC or Tyco plug-type connectors may be enclosed to
the inverter as options. These connectors may be used
instead of the screwed cable gland fittings-type fittings
mounted on the device (shipping condition). In this
case, please remove the screwed cable gland fittings-
type fittings and assemble the appropriate connectors
instead.
Figure 5.5: Assembly of Tyco connectors.
The assembly of the Tyco and MC-type connectors is
depicted in Figure 5.6 and. Figure 5.7.

Figure 5.7: Assembly of MC connectors
Open the screwed cable gland fittings
until you can insert the cables.
Fasten the cable ends in the terminals
marked “PV+” and “PV-“. Observe the
correct polarity.
Fasten the cap of the screwed cable
gland fittings.
Caution!
The PV generator should not be
disconnected from the Powador
inverter (i.e. by pulling the
connector) under load except in
absolute emergency cases. It
should by all means be avoided
during the normal grid feeding
operation.
Prior to disconnecting, always
disconnect grid voltage by
deactivating the grid fuses.
If this is not observed, arcing may
occur and damage the connectors
– both parts of the connector will
have to be replaced.
Caution
Remove the screwed cable gland -type
connectors from the provided apertures
in the baseplate of the inverter. Insert
the Tyco- or MC connector from outside
into the apertures and fasten them
inside by means of the black plastic
nuts (see Figure 5.5).
