Mounting
Observe these guidelines when mounting an FEC:
• Ensure the mounting surface can support the FEC,
DIN rail, and any user-supplied enclosure.
FEC26 Extended Temperature Field Equipment Controller Installation Instructions 1
• Mount the FEC on 35 mm DIN rail whenever
possible.
• 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 Figure 2: Back of FEC26 Controller Showing

Setting the Device Address
Metasys field controllers are master devices on
BACnet MS/TP (SA or FC) buses. Before operating
field controllers on a bus, you must set a valid and
unique device address for each controller on the bus.
