NOTE: If mounting more modules, mount only the last one of this group
and put the others aside. This reduces remounting time during drilling and
tapping of the next group.
7. Repeat steps 1 to 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using these DIN rails:
35 x 7.5 mm (EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).
Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN
rail mounting area of the module against the DIN rail. The latches will momentarily
open and lock into place.
Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or DIN rail).
1. Remove power. See important note on page 4.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches using a flat-blade or
phillips style screw driver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock)
to disconnect it from the module to be removed.
5. Gently slide the disconnected module forward. If you feel excessive
resistance, check that the module has been disconnected from the bus, and
that both mounting screws have been removed (or DIN latches opened).
NOTE: It may be necessary to rock the module slightly from front to back to
remove it, or, in a panel-mounted system, to loosen the screws of adjacent
modules.
6. Before installing the replacement module, be sure that the bus lever on the
module to be installed, and on the right-side adjacent module are in the
unlocked (fully right) position.
7. Slide the replacement module into the open slot.
