R1 Regenerative module r750-C
G1 ... Gx Interconnected drive systems
L1, L2, L3 Mains connections
Mains filters must be designed for the regenerative feedback mode with block current, e. g.
E94AZMP0494 (49 A, 3x500 V).
When operating inverters in a network, observe the information given in the documentation,
e. g. the maximum number of devices.
The inductance connected between regenerative module and mains must be maximally 0.6
mH.
