Panel Mounting
Mount the controller to a panel by using two screws per module. Use M4 or
#8 panhead screws. Mounting screws are required on every module.
IMPORTANT The grounding tab, located where you install the mounting screws, enables
the module to be grounded when it is panel-mounted.
This procedure lets you use the assembled modules as a template for drilling
holes in the panel. Due to module mounting-hole tolerance, it is important to
follow these procedures.
5. Place the modules back on the panel and check for proper hole
alignment.
IMPORTANT If mounting more modules, mount only the last one of this group and put the
others aside. This reduces remounting time when you are drilling and
tapping the next group of modules.
DIN-rail Mounting
The controller can be mounted by using the following DIN rails:
• EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
• EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
Before mounting the controller on a DIN rail, close the DIN rail latches.
Press the DIN rail mounting area of the controller against the DIN rail. The
latches will momentarily open and lock into place.
ATTENTION This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum and plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.

ATTENTION Do not remove the CompactFlash card while the controller is reading from or
writing to the card, as indicated by a flashing green CF status indicator. This
could corrupt the data on the card or in the controller, as well as corrupt the
latest firmware in the controller.
IMPORTANT Keep in mind that the Module Status indicator reflects the module state (for
example, self-test, firmware update, normal operation but no connection
established). The network status indicators, A and B, reflect network status.
Remember that the host is able to engage in local messaging with the card
although it is detached from the network. Therefore, the Module Status
status indicator is flashing green if the host has successfully started the
card. Note, however, that until the host removes reset, all status indicators
on the daughtercard remain off.
When you view the indicators, always view the Module Status indicator
first to determine the state of the daughtercard. This information may help
you to interpret the Network Status indicators. As a general practice, view
all status indicators (Module Status and Network Status) together to gain a
full understanding of the daughtercard’s status.
