NOTE
Observe the E-bus current
Observe the maximum current that your Bus Coupler can supply to the E-bus! Use the EL9410 Power Sup-
ply Terminal if the current consumption of your terminals exceeds the maximum current that your Bus Cou-
pler can feed to the E-bus supply.
The EL9930 has no further contacts such as power contacts or PE contacts.

If protection against overvoltage is necessary in your plant, provide a surge filter for the voltage supply to the
Bus Terminal blocks and the TwinSAFE terminals.
