10.
Risk of fire if two conductors are connected to one terminal
If you connect two conductors to a terminal, a fire can occur due to a bad electrical
connection.
• Never connect more than one conductor per terminal.
11.
Danger of crushing when locking levers snap shut
The locking levers close by snapping down fast and hard.
• Press the locking levers of the connecting terminal plate for the AC cable down with your
thumb only.
• Do not grip the entire connecting terminal plate for the AC cable.
• Do not place your fingers under the locking levers.
12. Connect PE, N, L1, L2 and L3 according to the labeling to the connecting terminal plate for the
AC cable and push the safety levers down. The direction of the rotating magnetic field of L1,
L2 and L3 is not relevant.
13. Make sure that all conductors are securely in place.
14. Tighten the swivel nut of the cable gland.
6.3.3 Connecting Additional Grounding
If additional grounding or equipotential bonding is required locally, you can connect additional
grounding to the inverter. This prevents touch current if the grounding conductor at the connecting
terminal plate for the AC cable fails. The required clamping bracket, the screw and the conical
spring washer are part of the scope of delivery of the inverter.
Cable requirement:
☐ Grounding cable cross-section: max. 16 mm²
