Electrical Connection
The modules are plugged on an I/O terminal unit
and TU542 for I/O Modules" on page 153. Properly position the modules and press until they
lock in place. The terminal units are mounted on a DIN rail or with 2 screws plus the additional
accessory for wall mounting (TA526
on page 1152).
The electrical connection of the I/O channels is carried out using the 40 terminals of the I/O ter-
minal unit. I/O modules can be replaced without re-wiring the terminal units.
