Each network engine application is different, and
no general guidelines can be given about the heat
dissipating devices that may be mounted in an enclosure
with the network engine. Monitor the network engine
processor temperature for each application to determine
the acceptable combinations of devices and proper
mounting location for your specific application.
Important:
Do not add any devices to an enclosure
with a network engine that could cause the
temperature of the network engine processor
to exceed 70˚C (158˚F). View the network
engine's CPU Temperature value on the network
engine's Diagnostic tab on the Metasys Site
for
ambient condition requirements, and refer to the
Troubleshooting
section of the
NAE Commissioning
Guide (LIT-1201519)
for additional information.
Mounting the Network Engine for wall
mount applications
To mount the network engine on a vertical surface:
1. Mark the location of the four wall mount feet on
the wall using the dimensions in Figure 5 and an
orientation shown in Figure 6, or hold the network
engine up to the wall and mark the hole locations.
Figure 5: Mounting screw hole dimensions, mm (in.)
2. Drill holes in the wall at the marked locations.
3. Insert appropriate wall anchors in all four holes (if
necessary) and insert the screws into the top two
holes. Leave enough space between the wall surface
and the screw head for the wall mount feet.
4. Hang the network engine on the screws with the
top wall mount feet for horizontal wall mount
applications. Hold the network engine in place for
vertical application.
Note:
The wall mount feet are designed to
make mounting easier. When the network
engine is wall mounted in the horizontal
orientation, you can hang the network engine
on the screws with the upper two mount feet
5. Insert the screws into the lower two wall mount feet
and holes and carefully tighten all of the screws.
Important:
Do not overtighten the mounting
screws. Overtightening the screws can crack
the network engine wall mount feet or housing.
Mounting the Network Engine for DIN rail
mount applications
To mount the network engine on DIN rails:
1. Mount two DIN rails horizontally, so they are 125 mm
(4.9 in.) apart on centers (Figure 4).
2. Snap the DIN clips on the bottom of the network
engine to the outward position.
3. Hang the network engine on the DIN rail hooks on
the back of the network engine.
Press the DIN clips back into position to secure the unit on
the DIN rails.
Figure 6: Required orientations for Network Engine
wall mount applications
To remove the network engine from the DIN rails:
1. Snap the DIN clips on the bottom of the network
engine to the outward position.
2. Lift the network engine off the DIN rails.
Mounting the Network Engine in a panel
To mount the network engine in a panel, follow these
requirements:
• Mount the panel in accordance with the manufacturer’s
instructions.
• Mount the network engine in the panel following the
guidelines in the
sections of this document.
Wiring Overview
Power supply, network, and
communication connections
See Figure 2 and Figure 3 for the location of the power
supply terminal, network communication terminals,
Ethernet jack, and modem jack.
Depending on the model, the network engine can
connect to an MS/TP field bus trunk, an N2 Bus trunk,
or a LonWorks network trunk. Also, all network engines
support multiple vendor integrations, including Modbus,
M-Bus, and KNX. See Table 21 for a list of all supported
trunk applications. The rules, guidelines, and wiring
considerations for each type of network or field bus
application are provided in tables of this document.
