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 [
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 /
4 Check secure fit of all connected cables.
5 Tighten AC cable fittings [
» 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.
› Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently
short.
Detailed information on grid connection: See comprehensive manual under
downloads in the "Hybrid and battery inverter" category.
4.4 Connecting the battery to the device
DANGER
Risk of fatal injury due to electric shock!
When connecting the batteries and installing supply lines, arcs may occur that may cause serious injury and
property damage.
› Insert internal fuse before connecting the DC voltage.
› Repair damage to the DC line without delay.
› Batteries must be fitted with potential equalisation in protection class I and with double-insulated DC
cable in protection class II.
CAUTION
Danger caused by reverse polarity at the DC connection.
The device does not have reverse polarity protection on the DC connection. This can lead to destruction of
the device.
› Check polarity using suitable measuring equipment before connecting the DC cable.
› Failure to observe these warnings may lead to device damage which is not covered by the manufac-
turer warranty.
4.4.1 With preload unit
NOTE
Device variant L: The insulation is 1-pin.
Device variant XL: The isolation is on all pins.
