Removing and Inserting
Modules
Warning
When removing and inserting the front connector during operation,
hazardous voltages of more than 25 V AC or 60 V DC may be
present at the module pins. When this is the case at the front
connector, live modules may only be replaced by electrical
specialists or trained personnel in such a way that the module pins
are not touched.
Install an analog input/output module as follows:
Step
Action
1
Release the upper locking bar on the subrack and swivel it
upwards and out.
2
Insert the module at the desired slot in the subrack and push
it back in the guides.
3
Latch the module by rotating the locking pin by 90
o
at the
lower end of the module.
It must no longer be possible to pull the module forwards.
4
Engage the front connector on the support pin of the module.
The width of the support pin also provides keying to prevent
front connectors from being fitted to the wrong modules (e.g.
front connectors with 115/230 V AC wiring cannot be
plugged into analog modules).
5
Tighten the screw in the upper part of the front connector.
