Configuration
- XG2 (vector surge, phase rotation) – ANSI 78V
The relay XG2 of the easy PROFESSIONAL LINE provides reliable protection for generators in parallel operation with the mains, by switching off very quickly in case of mains failure.
Supervision of the phase sequence is also possible.
Connecting two-wire system (1∿ 35 … 78 Hz), DIP-switch setting Y
Connecting three-wire system (3∿ 35 … 78 Hz), DIP-switch setting Δ
Connecting four-wire system (3/N∿ 35 … 78 Hz), DIP-switch setting Y or Δ
