Mounting Procedure for PM8xx and CI8xx Units, Complete with Baseplates
This topic does not apply to PM891. See
page 70.
Before mounting any processor unit or communication interface onto the DIN-rail,
read carefully the installation instructions provided with the equipment. Since the
electronic unit and baseplate are supplied as a single unit, there is no requirement to
separate them during the mounting procedure.
Mounting the units onto the DIN-rail only requires a blade screwdriver that fits
securely into the baseplate locking screw (1 mm slot). For further details on
mounting procedure, see
It is not allowed to manipulate CEX bus baseplates in a powered and running
system. Before changing or removing a baseplate, all CEX modules on that
segment must be removed.
Use the following procedure to mount the baseplates, complete with units:

Rotate the locking device to the OPEN position (1), hook the upper hook at the
rear of the unit baseplate securely over the upper edge of the DIN-rail and
gently snap the baseplate fully into the mounting position.
Rotate the locking device to the SLIDE position (2), slide the unit along the
DIN-rail to the desired mounting position and using the connector plugs and
sockets gently attach it to the adjacent unit baseplate.
To prevent damage to the pins, be sure the baseplate plugs and sockets are fully
aligned as the units interconnect. Under no circumstances use excessive force!
When interconnection is complete, rotate the locking device clockwise to
the LOCKED position (3). The baseplate is now fully locked into position and
has a good ground connection to the DIN-rail.
It is essential that the locking device be placed in the LOCKED position to
avoid possible problems caused by vibration and/or intermittent grounding.
