NOTE: for the details of the wiring diagram of each single accessory, please refer to the pages
describing that specific accessory.
In addition, the terminal box of the Emax E1.2 circuit-breaker has two differences compared to the terminal
box for Emax E2.2-E4.2-E6.2 circuit-breakers:
• Module compartments: Emax E1.2 can house three modules (one Ekip Supply + two other modules),
whereas E2.2-E4.2-E6.2 can house four modules (one Ekip Supply + three other odules).
• Ekip Signalling 4K: Emax E1.2 does not have the connections for Q5...Q10 / Ekip Signalling 4K.
In the following chapters, the terminal box considered is always that one of E2.2-E4.2-E6.2 circuit-breakers.
