3.3 Replacing module inserts
3.3.1 Input/output modules
Replacement of a module insert, using the example of a multichannel controller module 705010
For service purposes (or when retrofitting options for the multichannel controller module), the
case (D) can remain in the system; only the module insert (B) is replaced. For this purpose, the
system does not need to be isolated from the voltage supply (hot swapping).
The system will detect a module insert of the same type that has been replaced and will auto-
matically reconfigure it. Retrofitted functions for the multichannel controller module (expansion
slots) must be configured using the setup program or the multifunction panel.
The new module insert also has a new nameplate (G), which will differ from the old one at least
with regard to the fabrication number, and is no longer identical to nameplates (E) and (C) on
the case (D).
Therefore, in the event of replacement, the module insert will be supplied along with a new
nameplate that will be affixed to the case (D) in place of the old nameplate (C). This means that
the specifications of nameplates (G) and (C) once again correspond to one another.
DANGER!
With multichannel controller module 705010 and relay module 705015, the load circuits from
relay or solid state relay outputs can be operated with a dangerous electrical voltage (e.g.
230 V).
There is a risk of electric shock.
The load circuits are to be disconnected from the voltage supply prior to removing the wired
terminal strips. This work must only be performed by qualified personnel.
