Installing Field Wiring
Danger!
Risk of Explosion
Front connections that are improperly wired can result in dangerous mistakes being made and
cause potentially explosive mixtures to ignite.
1. The I/O modules are wired differently depending on the model and function. Wire the termi-
nal blocks to the field devices in accordance with the information in the data sheets for the
I/O modules used.
2. Pay attention to the conductor cross sections. We recommend that you do not exceed a
conductor cross section of 0.75 mm
3. Make sure that conductors are insulated all the way up to the terminal.
4. If you use stranded conductors, make sure that these are equipped with wire end ferrules.
We recommend using wire end ferrules approved according to DIN 46228-4.
5. Use green terminal blocks/protective covers for non-intrinsically safe circuits and blue
terminal blocks/protective covers for intrinsically safe circuits.
6. Maintain a minimum clearance of 50 mm between the intrinsically safe and non-intrinsically
safe circuits. Insert a separation wall (see chapter 3.5) or, if necessary, use protective
covers (see chapter 2.6.2).
7. Plug the terminals into the front sockets of the corresponding I/O modules and tighten the
terminals using the side screws.
8. Fit the cables for intrinsically safe circuits such that they are separate from non-intrinsically
safe circuits. Secure the cables of non-intrinsically safe circuits using cable ties.
9. Connect unused cables to terminals or ensure that unused cables are fixed securely and
insulated.
