MOUNTING THE DIN RAIL
At each installation site, mount the DIN rail and DIN rail mount modules (e.g. transceiver, I/O modules, power
supply) in a NEMA enclosure appropriate for the environment and hazardous area classification. Refer to Figure 3
for transceiver and I/O module dimensions. Allow room for:
o
Physically mounting and wiring the modules and for antenna, power, ground and signal wire runs
o
Accessories (e.g. low loss cable and MCX to N-type connector adapter, surge voltage protection adapter)
o
Conduit adapters
o
Operator controls
o
Circuit protection/safety devices (e.g. switches, circuit breakers, or fuses)
o
Other items as determined by the installer/user.
Fasten the DIN rail to a rigid panel within the enclosure using user-supplied hardware. An enclosure is required in a
hazardous area installation. In a non-hazardous area, a secure enclosure can provide safety for area personnel and it
restricts access to the equipment.
IMPORTANT
The DIN rail must be grounded. When mounting the DIN rail in a non-conductive
enclosure, install a ground wire between the rail and the single point ground.
DIN Rail Mount Transceiver or I/O Expansion Module
Figure 3 Physical Dimensions
MOUNTING A TRANSCEIVER OR I/O MODULE
I/O Expansion Modules may be mounted on a section of DIN rail in any sequence. Mount the Transceiver at either
end of the row of up to 8 I/O modules, to ensure sufficient heat dissipation.
IMPORTANT
If a module contains configuration switches that have not been set, refer to I/O Module
Configuration Switch Selections on page 11 before installing the module on DIN rail. A list
of modules with configuration switches is provided in the referenced section.
At each installation site, the transceiver and I/O modules are interconnected by built-in bus connectors; see Figure 4
below. Each module has male bus connectors on one side and female bus connectors on the other. When mounting
modules on a DIN rail, be sure to correctly orient modules so they interconnect and the module faceplates are
oriented for easy reading. Refer to the following procedures to install modules.
