Connection of the PV modules

DANGER
Danger of death or severe injuries from
dangerous voltage
Dangerous voltages can be present at the
DC connections of the solar power inverter.
► Never disconnect the PV modules when
the solar power inverter is under load.
First switch off the grid connection so
that the solar power inverter cannot
feed energy into the grid. Then open the
DC switch.
► Secure the DC connections against be-
ing touched.
NOTE
► To ensure protection conforming to IP65
all unused connections and interfaces
must be closed using the covers on the
solar power inverter.

General instructions

Check the polarity of the DC voltage at the DC connections
before connecting the photovoltaic system.
The PV module strings are connected to the DC connec-
tions, with the negative DC pole connected to DC MINUS
and the positive DC pole connected to DC PLUS. The con-
nections are coded to prevent incorrect polarity.
The maximum input voltage of the solar power inverter is
900 V when feeding the grid. The maximum current load at
each DC connection is 29 A.
The solar power inverter can be grounded at either the DC
plus side or the DC minus side. The DC side of the solar
power inverter has an isolation and grounding monitor. The
monitoring can be configured in the 230 Grounding menu,
see "10.5.2 Isolation and grounding monitoring", p. 44.
The solar power inverter has a DC disconnector.
Tools and devices required
Not supplied in the scope of delivery:
▪ Single-core cable for DC connections.
The ground connection must be installed in the immediate
vicinity of the solar power inverter. We recommend using
the "Grounding Set A Solar" grounding kit from Delta.

▪ UTE kit according to the current French standard UTE
C 15-712-1
The Multi-Contact UTE Kit is designed to conform to the
latest French standard UTE C 15-712-1. It contains 8 DC
measuring elements, a mounting tool and an additional
signal-flash drive. This kit allow you to conform to the DC
protection and signal requirements specified in UTE C
15-712-1.

RS485 interface (EIA485)

NOTE
► To ensure protection conforming to IP65
all unused connections and interfaces
must be closed using the covers on the
solar power inverter.
► Only the cables described below may
be used. Standard cables are not
permitted.
One or more solar power inverters can be connected to
a monitoring system via the RS485 interfaces. The two
RS485 interfaces are internally wired 1:1. Each RS485
interface can be used as an input or output.
