6. Attach the modules to the panel by using the mounting screws.
7. Repeat steps 1 … 6 for any remaining modules.
Mount to a DIN Rail
The module can be mounted by using the following DIN rails:
•
35 x 7.5 mm (EN 50 022 - 35 x 7.5)
•
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.
Replace a Single Module
Within a System The module can be replaced while the system is mounted to a panel
(or DIN rail). Follow these steps in order.
1. Remove power.
2. On the module to be removed, remove the upper and lower
mounting screws from the module or open the DIN latches by
using a screwdriver.
3. Move the bus lever to the right to disconnect (unlock) the bus.
TIP
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.
ATTENTION
Remove power before removing or inserting this module. When
you remove or insert a module with power applied, an electrical
arc may occur. An electrical arc can cause personal injury or
property damage by:
•
sending an erroneous signal to your system’s field devices,
causing unintended machine motion.
•
causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector and may lead to premature
failure.
