Wiring
Important:
Do not apply voltage to the RS-485
output, BACnet
®
output, analog output, or control
output. Severe damage may occur to the unit if
voltage is applied.
Important:
Do not connect more than 24 VAC to any
terminal.
Important:
Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
Important:
Do not exceed the unit’s electrical
ratings. Exceeding the unit’s electrical ratings can
result in permanent damage to the modules and void
any warranty.
Important:
Run all low-voltage wiring and cables
separate from all high-voltage wiring. Shielded
cable is strongly recommended for input (sensor)
and analog output cables that are exposed to high
electromagnetic or radio frequency noise.
Important:
Electrostatic discharge can damage
the unit. Use proper Electrostatic Discharge (ESD)
precautions during installation and servicing to avoid
damaging the unit.
Important:
Do not connect supply power to the unit
before checking all wiring connections. Short circuits
or improperly connected wires can result in damage
to the unit and void any warranty.
Wiring Recommendations
Use 18 to 22 AWG (1.0 to 0.6 mm diameter) stranded wire.
Follow good wiring practices:
• Control cables should cross power cables at a 90-degree
angle.
• Use a consistent color code to maintain polarity.
• Use a series configuration (daisy-chain wiring) for
connecting the NSD to room pressure monitors and
controllers.
Wiring Procedure
1. Remove the connectors from the back of the NSD.
2. See Figure 2 for proper wiring installation. If
additional options need to be wired, refer to
building prints for the proper wiring diagram.

RPM1600 Series Room Pressure Monitors,RPC1611 Room
Pressure Controllers, and NSD1380 Nurses Station Display
Important:
Wire the NSD exactly as the wiring
diagram shows. Making modifications to the
wiring may severely damage the unit.
Important:
Use MS-BACEOL-0 end-of-line (EOL)
terminations if the installed device is the last
device in the communications chain. The 100
Ohm reference resistors are optional.
3. Plug the connectors back into the NSD.
4. Carefully push the wires into the electrical box and
mount the NSD. Install four screws to hold the NSD
firmly to the base.
5. Press the cover plate onto the NSD1380 Nurses
Station Display.
