Connection of inputs on the -SX / -SX2 models

For the string connections on the -SX /-SX2 versions, it is necessary to

use the quick t 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 t 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 t 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)

Using corresponding parts that are not compliant with the quick t connector models on the

inverter could cause serious damage to the unit and lead to invalidation of the warranty.

Connect all the strings required by the system, always checking the seal

of the connectors.

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

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 eld 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.
