ENGLISH
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.
