Connection cables, Flex-S3 Trunk Connectors and Extension Connectors build a custom AC trunk. A Flex-S3 Cable Terminal Connector turns an AC cable into the end cable to the distribution board, and a Flex-S3 Sealing Cap covers an unused trunk-connector port. The connectors are 2P+PE, 300 V and 40 A, IP68 and UL 94-V0; the cable carries a UV rating according to 2 PfG 1940.
On 4 mm² Hoymiles specifies a maximum of 15 to 26 HMS-1T, 7 to 13 HMS-2T or 3 to 4 HMS-4T units per branch (230 V, depending on the power rating); always follow local requirements. The Flex-S3 system does not fit the MIS series (Flex-S2) or the three-phase HMT series.
