NPB-PWR-UN
The NPB-PWR-UN module lets you power the T-600 (and if installed, T-IO-16 modules) from AC line power,
with a universal input range from 90–263Vac. If installing T-IO-16 modules, the NPB-PWR-UN installs as the
last
(end) module in the chain. See
Warning
•
A 120Vac or 240Vac circuit powers the NPB-PWR-UN.
Disconnect power
to this circuit
before installation to prevent electrical shock of equipment damage.
•
Make all connections in accordance with national and local electrical codes. Use copper
conductors only.
•
Do not exceed the 30W capacity of the NPB-PWR-UN by the powered devices.
Power input connections are made to the terminals on the circuit board (cover removal is required). An earth
ground connection must be made to the grounding lug using the supplied earth wire. See
.

Procedure 3
Wiring NPB-PWR-UN input power and earth ground.
Step 1
Remove power
from the AC circuit being wired to the NPB-PWR-UN—see previous
.
Step 2
Remove the NPB-PWR-UN cover.
To do this, press in the four tabs on both ends of the unit, and lift the cover off.
Step 3
If the controller or a T-IO-16 accessory module is plugged into the unit, you may need to slide it away
to get to the cover tabs.
Step 4
Connect the supplied earth grounding wire to a nearby grounding point. See
.
Step 5
Make AC circuit connections line (mains) and neutral to the terminals labeled “INPUT PWR.”
Step 6
Replace the cover on the NPB-PWR-UN.
Make sure all modules in the mounted assembly are firmly connected together and secured.
Caution
Do not energize the AC circuit wired to the NPB-PWR-UN until all other JACE mounting and
wiring is completed. See

NOTE:
The 6-pin connector of the NPB-PWR-UN is
not used with a T-600 series controller.
The 6-pin connector is designed for use with other
controllers or modules, and must be left unused.
