Mounting
Observe these guidelines when mounting an FEC
extended temperature controller:
• Ensure the mounting surface can support the FEC,
DIN rail, and any user-supplied enclosure.
• Mount the FEC on 35 mm DIN rail whenever
possible. Figure 1: Controller Mounting Positions
• Mount the FEC in the proper mounting position
(Figure 1).
• Mount the FEC on a hard, even surface whenever
possible in wall-mount applications.
• Use shims or washers to mount the FEC securely
and evenly on the mounting surface.
• Mount the FEC in an area free of corrosive vapors
and observe the Ambient Conditions in the
Technical Specifications section.
• Provide for sufficient space around the FEC for
cable and wire connections, easy cover removal,
and good ventilation through the controller (50 mm
[2 in.] minimum on the top, bottom, and front of the
controllers).
• Do not mount the FEC on surfaces prone to Figure 2: Back of FEC16 Controller Showing
vibration, such as duct work, or in areas where Extended Mounting Clips, DIN Rail Channel, and
electromagnetic emissions from other devices or
wiring can interfere with controller communication.

FEC Terminal Blocks and Bus Ports
See Figure 3 for terminal block and bus port locations
on the FEC16 controller. Observe the following
guidelines when wiring an FEC controller.
Input and Output Terminal Blocks
All of the fixed input terminal blocks are mounted on
the bottom of the FEC. The output terminal blocks are
mounted on the top of the controller. See Table 1 for
more information.

FC Bus Port
The FC Bus port on the front of the FEC is an RJ-12,
6-position modular jack that provides a connection for
the Wireless Commissioning Converter or ZFR1811
Wireless Field Bus Router.
The FC Bus port is connected internally to the FC Bus
terminal block. See Table 3 for more information. The
