If desired, you can use the wall mount WPM-
XXX
in your office (to initially commission the T-600), and then
install the T-600 at the job using either a NPB-PWR or NPB-PWR-UN module. The following sections provide
more details:
•
(24Vac/dc-powered in-line module)
•
(Universal 90V–263Vac-powered in-line module)

NPB-PWR
Using the NPB-PWR module lets you power the T-600 (and if installed, T-IO-16 modules) from a
dedicated
Class 2, 24Vac transformer, or from a 24Vdc power supply. If installing T-IO-16 modules, the NPB-PWR
installs as the
last
(end) module in the chain. See
Note
If powering from a 24V transformer, do
not
power any other equipment with it. Otherwise, conducted
noise problems may result. Also, do not ground either side of the transformer’s 24V secondary.

NPB-PWR module wiring connections.
Located at the bottom of the NPB-PWR module is a 2-position power connector, and an earth ground spade lug,
as shown in
.
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 in
Caution
Do not plug 24V power into the NPB-PWR (reinsert connector plug) until all other mounting and
wiring is completed. See
“Power Up and Initial Checkout,”
Power consumption depends on installed accessories and option boards, and may vary from:
•
T-600 with NPB-PWR module alone: approximately 8.5 VA (AC) or 8.5 W (DC)
•
T-600 with NPB-PWR and four (4) T-IO-16 modules, and option cards: up to 20 VA (AC) or 20 W (DC)
