Installation
5.
Correctly fit the plug on the positive cable and the
socket on the negative cable. The inverter is
equipped with plug connectors from PHOENIX
CONTACT (type SUNCLIX). Be absolutely sure to
take note of the manufacturer's latest information
(e.g. use of tools, permitted torques, etc.)

when
installing.
Pay attention to the correct polarity when mounting
the sockets and the plugs on the DC cables of the
solar modules! The poles of the PV strings (PV field)
must not be earthed.
6.
Plug the sockets and plugs of the DC cables onto
the inverter. Keep the plug seals from the plug
connectors.

IMPORTANT
INFORMATION
The cross-section of the DC cables
should be as large as possible,
a maximum of 4 mm² for flexible
cables and 6 mm² for rigid cables.
We recommend using tin-plated
cables. If non-tin-plated cables
are used, the copper strands may
oxidise, as a result of which the
transition resistance of the connec-
tions will be too high.
IMPORTANT
INFORMATION
The types of solar module used, the
number of solar modules and their
orientation, should be the same for
all PV strings.
If two PV strings are jointly con-
nected to one DC input (e.g. DC1)
using a Y-splitter, these strings
and the parallel string (e.g. DC1/
DC2) must also be protected using
separate string fuses.
