Wiring NPB-PWR-UN-H/U input 

power and earth ground.

1.

Remove power from the AC circuit being wired to 

the NPB-PWR-UN-H/U. See the previous Warning.

2.

Remove the NPB-PWR-UN-H/U cover. To do this, 

press in the four tabs on both ends of the unit, and 

lift the cover off. If the controller or a IO-16-H/U 

accessory module is plugged into the unit, you may 

need to slide it away to get to the cover tabs.

3.

Connect the supplied earth grounding wire to a 

nearby grounding point. See Fig. 5.

4.

Make AC circuit connections line (mains) and neu-

tral to the terminals labeled “INPUT PWR.”

5.

Replace the cover on the NPB-PWR-UN-H/U mod-

ule. Make sure all modules in the mounted assem-

bly are firmly connected together and secured.

CAUTION

Do not energize the AC circuit wired to the 

NPB-PWR-UN-H/U until all other controller 

mounting and wiring is completed. See “Power 

Up and Initial Checkout” on page 12.

NPB-WPM-US/U 

(Wall Mount AC Adapter)

The NPB-WPM-US/U is a self-contained, isolated, Class 

2, switching power supply designed to plug into a 

standard building power receptacle of appropriate voltage. 

To supply power to the controller, you simply plug the 

barrel connector plug from the NPB-WPM-US/U into the 

barrel power connector on the controller’s base board 

(see Fig. 3 on page 5).

NOTE: The adapter’s 15W output rating is derated 

50% at the 60°C (140°F) maximum ambient 

temperature (for a controller 

without

 a NiMH 

battery), such that 

no I/O modules are sup-

ported at 60°C

. See “Environmental Require-

ments” on page 3.

CAUTION

Do not plug the barrel connect plug from the 

NPB-WPM-US/U into the controller until all 

other mounting and wiring is completed.

See “Initial power up and checkout.” on page 12.

Communications Wiring

Communications ports are on the controller’s bottom side, 

which include:

• Ethernet

• Serial

NOTE: Prior to connecting cables, provide strain 

relief for them to prevent damage to the 

controller.
