7.5.1
Preparing the grid connection
↻
A connection cable with 4 cores (4 individual cores or multi-core up to max. ca-
ble cross-section 0,63 - 1,10 inch ) is available on the device.
↻
Nominal grid voltage matches the VAC nom name plate details.
1 For improved accessibility: Unfasten the AC input plate using the 6 screws [
T_30]
2 Unfasten the cable fitting for AC connection and PE earth (ground) [ W_46].
3 Remove sealing plug.
4 Guide the AC leads through the cable fittings.
5 Strip the insulation from the AC cables.
6 Strip the insulation from individual wires for L1 / L2 / L3 (ABC) and PE (ground)
so that the strand and insulation can be pressed into the cable lug shaft.
CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be suitable
for the conductor material and copper busbars being used.

7 Press on cable lug.
8 Affix shrink tubing (not included as standard) over the shaft of the ring cable lug
of the AC cable.
9 For improved accessibility: Fasten the AC attachment plate by tightening the 6
fastening screws [ T_30 / 53.10 In-Ibs ]

When using aluminum cable lugs we recommend using cable lugs with galvanic tin plating or, alternatively, AL/CU ca-
ble lugs with suitable AL/CU washers.
Otherwise, with the electrolytes present (e.g. Condensation water), the aluminum could be destroyed by the copper
bus bars.
