Weidmuller Transclinic 16i+ Bedienungsanleitung Seite 60

WARNING
All PV current inputs (positive or negative depending on Transclinic xi+
model) must belong to the same inverter's MPPT.
Wiring of the copper busbar
The copper busbar (negative or positive depending on Transclinic xi+ model) collects
and parallels the current from the individual PV current inputs. All four hex nuts in
the copper busbar must be properly tightened regardless of whether there is a wire
connected to it or not. Always wire the copper busbar which input terminal blocks
contain wires. Wires connected to the copper busbar must be terminated with M6
tubular cable lugs. Examples of proper cable lugs are Cembre's A3-M6 for 16 mm²,
A5-M6 for 25 mm² and A9-M6/15 for 35 mm².
WARNING
Only the hex nuts of the negative copper busbar need to be tightened.
The remaining non-hex nuts are factory-tightened and shall neither be
retightened nor untightened.
sure there is enough contact surface between the copper busbar and the
lug; moreover the cable lug shall not contact the non-hex nuts of
the copper busbar (do not use aluminum lugs and lugs wider than
15 mm). Failure to observe these requirements will create a fire hazard in
the equipment.
It is required to wire one of these Weidmüller surge protective devices to the
copper busbar (negative pole in case of Transclinic 16i+ or Transclinic 16i+ 1k5 L;
positive pole in case of Transclinic 16i+ 1k5 H) (for more information please check
CLC/TS 50539–12:2013 or equivalent local standard). If in the combiner box the copper
busbar is connected to a DC switch-disconnector, it is fine to wire the SPD to the switch-
disconnector instead.
