Connecting the device to the power grid

7.4.1 Preparing the grid connection
↻ Time required for AC connection: 30 min
↻ The nominal grid voltage matches the "VAC nom" specification on the name
plate.
1. Unfasten the cable fitting for AC connection and PE earth (ground) [ W_46].
2. Remove sealing plug.
3. Insert the AC cables into the cable fittings.
4. Strip the insulation from the AC cables.
5. Strip the insulation from the individual cores for L1 / L2 / L3 (ABC), neutral con-
ductor (N) and PE (ground) so that the stranded wire and insulation can be
pushed into the shaft of the cable lug.
. CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be suitable
for the conductor material and copper busbars being used.
6. Press on cable lug.
7. Slip a shrink-fit sheath (not part of the scope of supply) over the shaft of the ring
cable lug of the AC cable.
8. Fasten the input plate using the 6 screws [ T_30 /
7.4.2 Making the grid connection
4-pole connection, TN, TT system
↻ Grid connection is prepared.
1. Loosen nut and lock washer at the marked grounding point.
2. Lay the grounding cable onto the grounding point. Secure it with the nut and
lock washer provided [ W_17 /
3. Place the cable lug of cores L1 / L2 / L3 on the busbar in accordance with the la-
beling and secure it with a nut, screw and lock washer (fastening elements in
scope of supply) [ W_17 / 30 Nm ].
4. Check secure fit of all connected cables.
5. Tighten AC cable fittings [ W_46 /
ð The device is connected to the power grid.
NOTE
Observe the general earthing recommendation of the existing mains system.
NOTE
When the line resistance is high, i.e. long cables on the grid side, the voltage drop on the line increases, and the
terminal voltage is higher or lower than the country-specific limit value, the device shuts down.
1. Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently short.
4
When using aluminium cable lugs we recommend using cable lugs with galvanic tin plating or, alternatively,
AL/CU cable lugs with suitable AL/CU washers.
Otherwise, the aluminium may be destroyed by the copper busbars in the presence of electrolytes (e.g. con-
densate).
5
If the connection is made in a TN-C grid, connect the PEN grounding cable to the ground earthing point.
