Wiring
Page 23 / 52
When connecting cables, the following details have to be considered:
1) Power supply cables must only be connected to the terminals L1, L2, and L3/N.
2) Do not connect any cables to the non-designated terminals in the upper terminal row (refer to
figure above) as these terminals are reserved for L2000 internal purposes.
3) If more than one motor is to be driven by a single inverter, thermal relays have to be provided
for each motor.

4) The leads from the power supply must be connected to the mains circuit terminals as follows:
Connect single phase power supply (50/60Hz) to terminals L1, L3/N.
Connect three phase power supply (50/60Hz) to terminals L1, L2, L3/N.
5) Don´t remove the short bar between the ter1 and +.
