Using corresponding parts that are not compliant with the quick fit connector models on the
inverter could cause serious damage to the unit and lead to invalidation of the warranty.
If any string inputs are not required, you must ensure that covers are installed to the connec-
tors, and install any which are missing.
This is necessary both for the inverter seal, and to avoid damage to the free connector which
IP65
may be used at a later time.
In these versions, is MANDATORY to directly connect the individual strings coming into the
inverter (do not make field switchboards for parallel strings). This is because the string fuses,
situated on each input, are not rated to take strings in parallel (array). This operation can
cause damage to the fuse and consequently malfunctioning of the inverter.
For the string connections on the -SX /-SX2 versions, it is necessary to
use the quick fit connectors (usually Weidmüller PV-Stick or WM4, Multi-
Contact MC4 and Amphenol H4) located on the bottom of the mechanic.
The input connectors are divided into 3 groups (one group for each input
channel) consisting of 5 pairs (4 pairs for the PVS-60-TL-SX-CN model)
of quick fit connectors.

Refer to the document "String inverter – Product Manual appendix" avai-
lable at www.abb.com/solarinverters to know the brand and the model of
the quick fit connector. Depending on the model of the connector of the
own inverter, it is necessary to use the same model and the respective
counterpart (check the compliant counterpart on the website of the ma-
nufacturer or in ABB)
Connect all the strings required by the system, always checking the seal
of the connectors.
