To remove the NIE from the DIN rail, snap the bottom DIN clips to the outward extended position and carefully lift
the NIE off the DIN rail.
Enclosure Mount Applications
Mount the enclosure in accordance with the manufacturer’s instructions, and then mount the NIE in the enclosure
following the guidelines in the
and
sections.
Wiring
Power Supply, Network, and Communication Connections
See
for the location of the NIE’s power supply terminal, bus terminals and ports, USB port, and Ethernet
port.
Note:
Do not remove the red terminal block keys from the board mounted terminal blocks. Removing the keys can
result in a removable terminal plug being plugged into the wrong terminal block, which can cause the NIE to
malfunction.
24~ Supply Power Terminal Block
The 24~ supply power terminal block is a gray, keyed, removable 3-terminal block located on the top side of all NIE
models (
and
).
In North America, the NIE requires a Class 2, 24 VAC, 25 VA minimum power supply. Outside North America, use
a 24 VAC safety extra-low voltage (SELV) transformer at the appropriate rating. A minimum input voltage of 20 VAC
is required for the NIE to operate properly.
Note:
The maximum power consumption of an NIE29 is 25 VA, but that does not include power for internally sourced
binary output (BO) points. Applications that provide power to BO points and configurable output (CO) points
configured as BO points can require up to 125 VA of additional power over the 25 VA minimum required for
the NIE29.
SA Bus Terminal Block
The brown, keyed, removable, 4-terminal
SA BUS
terminal block (
) is provided on all NIE models. Connect
the 4-wire SA Bus cable to the SA BUS terminal block. See the
section for more information.
SA Bus Modular Port
The 6-Pin modular
Sensor/Actuator (SA) Bus
port is available on all NIE models (
and
). The SA
BUS port connects to:
•
a Wireless Commissioning Converter (MS-BTCVT-1) to commission the NIE with the Controller Commissioning
Tool
•
a DIS1710 Local Controller Display to provide a display screen on NIE29 models without an integral display
screen
•
an NS Series Network Sensor to provide room temperature data to the NIE
