35.
❑
❑
The inputs of the power units are outside of the inverter wired in parallel with the DC
busbars.
36.
❑
❑
The DC feed lines between the DC busbars and the inputs of the inverter have been fused.
37.
❑
❑
The DC busbars have been dimensioned and fused for the maximum possible current
specified in the installation manual (see 5.7 Application examples).
38.
❑
❑
The DC feed lines between the PV module or MaxConnect and the DC busbars are fitted
with fuses. These have been fitted both on the plus pole and the minus pole.
39.

❑
The measurement of the AC voltage prior to commissioning the station revealed the follow-
ing values: SM330TS-SV: 270 V … 285 V / SM360TS-SV: 310 V … 330 V.
41.
❑
❑
The AC overvoltage protection conforms with the requirements of overvoltage category 2.
42.
❑
❑
The line cross section for the AC connection in the inverter is no less than
3 x 95 mm
2
per phase.
43.
❑
❑
The AC feed lines in the inverter have been correctly connected (mains phases are
clockwise). The tightening torque of the 9 nuts is in conformance with the specs in the
installation manual.
44.
❑
❑
The delivered phase separation elements have been fitted between the lugs inside the
inverter.
45.
❑
❑
Each inverter can be disconnected separately by an AC circuit breaker or an 800A NH fuse
switch disconnector on the AC side.
46.
❑
❑
The autonomous power supply transformer is fused on the primary and secondary sides.
