NOTE: If powering from a 24V transformer, do
not
power
any other equipment with it. Otherwise, con-
ducted noise problems may result. Also, do not
ground either side of the transformer’s 24V sec-
ondary.
Fig. 4. NPB-PWR-H module wiring connections.
Located at the bottom of the NPB-PWR-H module is a 2-
position power connector, and an earth ground spade lug, as
shown in Fig. 4.
Connect the supplied earth ground wire to a nearby earth
ground point. Unplug the power connector plug from the
module and make connections to it as shown.
CAUTION
Do not plug 24V power into the NPB-PWR-H
(reinsert connector plug) until all other mounting
and wiring is completed. See “Power Up and Initial
NPB-PWR-UN-H
The NPB-PWR-UN-H module lets you power the controller
(and if installed, connected I/O modules) from AC line power,
with a universal input range from 120–240Vac. If installing IO-
16-H modules, the NPB-PWR-UN-H module mounts as the
last (end) module in the chain. (see Fig. 1).
WARNING
•
A
120Vac or 240Vac circuit powers the NPB-
PWR-UN-H. Disconnect power to this circuit
before installation to prevent electrical shock or
equipment damage.
• Make all connections in accordance with
national and local electrical codes. Use copper
conductors only.
• Do not exceed the 30W capacity of NPB-PWR-
UN-H by the powered devices.

Wiring NPB-PWR-UN-H input power and earth ground:
1.
Remove power
from the AC circuit being wired to the
NPB-PWR-UN-H. See the previous Warning.
2.
Remove the NPB-PWR-UN-H cover.
