7.5.2 Make the grid connection
TN-S system, 5-core connection
1 Run L1, L2, L3, N through the included ferrite (60.0TL3 only).
2 Connect wires in accordance with the labels on the PCB terminals. [See figure
22] [} Page 20]
3 Connect terminals "PE" to the equipotential bonding of your lightning protec-
tion system using a 16 mm² wire
4 Check secure fit of all connected cables.
5 Tighten the cable fitting. [ W_46 /
» The device is connected to the power grid.
TN-C system
1 Fit the PE terminal (not included in the scope of supply) to the hat rail, note the
cable cross-sections!
2 Run L1, L2, L3 through the included ferrite (60.0 TL3 only).
3 Connect wires in accordance with the labels on the PCB terminals. [See figure
23] [} Page 20]
4 Check secure fit of all connected cables.
5 Tighten the cable fitting. [ W_66 /
» The device is connected to the power grid.
NOTE
An AC-side disconnection unit must be provided during the final installation stage. This disconnecter mech-
anism must be installed so that it can be accessed at any time without obstruction.
NOTE
If a residual current circuit breaker is necessary due to the installation specification, a type A residual cur-
rent circuit breaker must be used.
If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200kOhm in the
"Parameters" menu Menu.
For questions regarding the appropriate type, please contact the installer or our KACO new energy cus-
tomer service.
NOTE
When the line resistance is high, i.e. long cables on the grid side, the voltage at the grid terminals of the
device will increase in feed-in mode. If the voltage exceeds the country-specific grid overvoltage limit
value, the device switches off.
› Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently
short.
2
Only connect the overvoltage conductor to a "PE" terminal.
