Risk of injury through electric shock and damage to the device!

Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals!

Wiring 1:
KM2774 - Wiring

Connection for supply voltage (24 V)

CAUTION

Ground the 0 V potentials of the 24 V supply voltage.

Connect

    • the 0 V potential of the supply voltage (Us) of the Bus Coupler that controls the KM2774-1001 and
    • the 0 V potential of the KM2774-1001 supply voltage (X0, terminal point 3, 4 or 5)
      with the protective earth.
