Connection conditions
Type of connection: Wieland PST40i1C plug connector
Only use Wieland PST40i1C connectors (not included in the delivery).
Maximum DC input current per MPP tracker: 18 A
Maximum DC input voltage: 1 000 V
Select conductor cross sections to suit the plant conguration.
The maximum short-circuit current (Iscpv) is 25 A.
DANGER!
Fatal re risk!
High return currents can cause a re risk for the PV generator.
When Y plugs are used in order to connect more strands than specied,
each DC input conductor must be protected individually against dan-
gerous return currents.
Parallel connection of the MPP trackers is not permitted:
Figure 16 Unacceptable parallel connection of MPP trackers
Do not t a ground connection to either the negative terminal or the positive terminal
of the PV generator.
Procedure
1. Make sure that the DC disconnector is switched off.
2. Disconnect the AC power supply to the inverter.
3. Connect the DC input conductors that have been pre-tted with the connector.
4. Use the locking clips (included in the delivery) to secure the plug connectors.
