5.6.5 Electrical connection diagram
and electrical interfaces (inputs and outputs)
The cables are connected to the board in the connection box via the plugs on the
edge of the board. All electrical interfaces (galvanically isolated) are located here.
The plugs are secured with snap-in hooks. The connections and interfaces are sup-
plemented and explained in figures and sections.

Check that the connectors are secure!
Tighten the screws on any unused terminals!
Connect the cables and screens in compliance with the explosion pro-
tection regulations. In practice, the screens are not attached in explosion
hazard areas, but are only connected in the safe area.
