To Snap on a Single Module
•
Push up the module against the mounting rail from below, allowing the metal spring to
snap in between mounting rail and mounting area as illustrated.
•
Push the top of the module against the mounting wall until it snaps in.
6.1.3
To Interconnect Two Modules
•
After snapping on the first module to the rail, snap on the second module about 1 cm away
towards the right of the first module.
•
Push the second module along the rail towards the first module until you hear the locking
device snap in. Correctly mounting the modules is the only way of ensuring that the system
works properly.
•
To prevent inadmissible contamination, mount the cover of the module bus connectors on
the rightmost module of the c250-S system.
CAUTION
Short circuit fault of module bus contacts
A short of the module bus contacts may cause the communication with the safe
module to fail.
Verify that the cover of the module bus connector is mounted on the
rightmost module of the c250-S system.
