If you do not use a generator junction box, leave the sealing
plugs in place on the connector.
6.9 Connecting further string inverters
If you have chosen to use the Internet-based Conergy
SunReader monitoring system, connect the Conergy IPG
series string inverters to one another with a CAN cable.
Connect the first inverter to the Conergy SunReader (
CAN In )
(see Fig. 6-1, page 35, pos.
(1)
). Fit a terminator to the last
inverter (see chapter 6.10, page 46). The terminator is
included in delivery of the Conergy SunReader.
If you do not use a Conergy SunReader, leave the sealing
plugs in place on the connectors
6.10 Connecting the terminator
You must install a 120
Ω
terminator at the end of a CAN
connection. The terminator is included in delivery of the
Conergy SunReader. The terminator is installed as a bus
connector between pin 4 (CAN-high) and pin 5 (CAN-low) in
an adapter.
Connecting further string inverters
1. Screw one end of the CAN cable to the first string inverter
( CAN In ).
2. Screw the other end of the CAN cable to the next string
inverter ( CAN Out ).
CAUTION!
Short circuit due to inadequate terminator.
An inadequate terminator can cause damage from a short
circuit.
Connecting the terminator
1. Connect the adapter with the integrated terminator to the
CAN Out connection.
2. Tighten the plug by turning manually.
