Connecting The Strings To The Dc Safety Unit - SolarEdge SE11400H Installation Manual

Connecting the Strings to the DC Safety Unit

NOTE
Connect the equipment grounding before connecting the AC wires to the AC terminal block.
Veillez à relier le conducteur de PE (la terre) avant de connecter les fils CA au bornier CA.
4. Connect the wires to the appropriate terminal blocks according to the labels on the terminal blocks
(N, , L1 and L2).
5. Use a standard flat-blade screwdriver to connect the wires to the spring-clamp terminals:
The screwdriver blade should fit freely in the terminal opening. Too large a blade can crack the
l
plastic housing.
Insert the screwdriver and press the release mechanism and open the clamp.
l
Insert the wire into the round opening and remove the screwdriver – the wire is automatically
l
clamped.
Verify that there are no unconnected wires.w

Connecting the Strings to the DC Safety Unit
You can connect systems with multiple DC strings in parallel to the DC input terminals of the DC Safety
Unit. Inverters may have a different number of pairs of DC input terminals, depending on the inverter
power rating. If more strings are required, they can be connected in parallel using an external combiner
box before connecting to the DC Safety Unit. When connecting multiple strings, it is recommended to
run separate circuits to the DC Safety Unit or to position the combiner box near the DC Safety Unit. This
simplifies commissioning by allowing testing and servicing near the inverter.
NOTE
Use 16-6AWG, 75-90°C copper wires only.
