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).
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.
8. Connect the modules together by locking (fully left) the bus levers on the replacement
module and the right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
TIP
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.
