Wiring power modules
Terminal module terminals
Power modules are either integrated to the head module or may be installed between the extension
modules. With power modules, terminals with spring clamp technology are used for wiring. The
spring clamp technology allows quick and easy connection of your signal and supply lines. In con-
trast to screw terminal connections this type of connection is vibration proof.
