If desired, you can use the wall mount NPB-WPM-US/U in
your office (to initially commission the controller), and then
install the controller at the job using either a NPB-PWR-H/
U or NPB-PWR-UN-H/U module. The following sections
provide more details:
• “NPB-PWR-H/U” on page 8 (24 Vac/dc-powered in-line
module)
• “NPB-PWR-UN-H/U” on page 8 (Universal 120V–
240Vac-powered in-line module)
• “NPB-WPM-US/U (Wall Mount AC Adapter)” on page 9
NPB-PWR-H/U
Use the NPB-PWR-H/U module to power the controller
(and if installed, IO-16-H/U modules) from a dedicated
Class 2, 24Vac transformer, or from a 24Vdc power
supply.
NOTE: If there is no optional NiMH backup battery,
using the NPB-PWR-H/U allows a higher
operating temperature. See “Environmental
NOTE: If powering from a 24V transformer, do not
power any other equipment with it. Other-
wise, conducted noise problems may result.
Also, do not ground either side of the trans-
former’s 24V secondary.
Fig. 4. NPB-PWR-H/U module wiring connections.
Located at the bottom of the NPB-PWR-H/U 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/U
(reinsert connector plug) until all other
mounting and wiring is completed. See “Initial
power up and checkout.” on page 12.
NPB-PWR-UN-H/U
The NPB-PWR-UN-H/U 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/U modules, the NPB-PWR-
UN-H/U module mounts as the last (end) module in the
chain. (See Fig. 1 on page 4).
WARNING
• A 120Vac or 240Vac circuit powers the NPB-
PWR-UN-H/U. 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/U by the powered devices.
