AC Terminal: 1-Phase ENS
The Wieland RST 3i connector plug intended for the AC terminal is enclosed.
(1) N
(2) L1 (feed phase)
(3) PE
When connecting several inverters:
• Distribute inverters evenly (as regards their power) between phases of the mains
supply
AC Voltage Connection
Establish AC voltage connection as follows:
• Establish a connection to the power supply system with a cable on the AC terminal
as follows:
- with the Wieland RST 5i plug connector (3-phase ENS) supplied with the system,
or
- with the Wieland RST 3i plug connector (1-phase ENS) supplied with the system.
• Fuse the AC output with a fuse rating of not more than 25A
• Use lines matching the type-dependent AC
• Mind different terminals for connection to AC mains power supply depending on
whether 1-phase ENS or 3-phase ENS is used
DC Voltage Connection
Establish DC voltage connection as follows:
• Establish a connection to the solar panel on the DC input with a cable with a DC
plug connector
• If more than one strand is connected, ensure that the number and type of solar
modules and the PV power are identical for every strand
