Thermally favorable arrangement of the TwinSAFE terminals
The following structure is thermally favorable, since between the coupler / power supply terminal and
terminals with rather high waste heat, terminals with low current consumption and thus rather low waste heat
are placed.

Electrical installation
4.2.4.1
Connections within a Bus Terminal block
The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:
Spring contacts (E-bus)
The six spring contacts of the E-bus deal with the transfer of the data and the supply of the Bus Terminal
electronics.
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.
Power contacts
The power contacts deal with the supply for the field electronics and thus represent a supply rail within the
Bus Terminal block. The power contacts are supplied via terminals on the Bus Coupler.
