3.6 Field Wiring
Field connections can be made to the I/O modules using screw terminals, front screw
terminals, or spring terminals. Use the terminal blocks from the range of accessories. See
chapter 2.6.2
Front screw terminals or spring terminals are ideal for performing extensions at a later point or
for changing individual field connections, as the plug can remain in the front socket of the I/O
module during wiring. These terminals offer a test plug socket for measuring individual current
circuits.
Danger!
Risk of explosion
Measuring instruments that do not meet the requirements for use in hazardous areas can
cause explosive mixtures to ignite.
Only use accessories and devices that are approved for use in the respective environment.
Caution!
Loss of intrinsic safety
Circuits with the Ex i type of protection that have been operated with non-intrinsically safe
circuits must no longer be used as circuits with Ex i type of protection.
Use only Ex i-certified measuring instruments in conjunction with Ex i-certified I/O modules.
