NOTE
If one of the MPP trackers (A or B) is not used, then it must be short-circuited, otherwise faults can
occur during the self-test of the unit and the feed-in operation is not guaranteed. The short-circuit-
ing of an unused MPP tracker does not result in the device being damaged.
The recommended standard connection should always be used as a matter of course before an MPP
tracker is short-circuited and therefore remains unused.
7.3.4 Connecting the PV generator
DANGER
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched. When there is solar radiation, DC
voltage will be present at the open ends of the DC leads.
›
Do not touch the exposed ends of the cables.
›
Avoid short circuits.
Connecting the PV generator
1. Remove protective caps from the DC connection plugs.
2. Connect PV generator to the DC plug connectors on the underside of the housing.
3. Ensure that the unused plug connectors are sealed with protective caps.
» The inverter is connected to the PV generator.
7.4 Connecting the interfaces
All interfaces are located on the connection circuit board underneath the cover for the connection area. For connec-
tion, use the cable fittings and plug connections provided (see Figure 26 on page 25).
DANGER
Risk of fatal injury due to electric shock
Severe injury or death may result from improper use of the interface connections and failure to
observe protection class III.
›
The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with
protection class III.
NOTE
When routing the interface connection cable, note that too little clearance to the DC or AC cables can
cause interference during data transfer.
