POWER WIRING
It is recommended that the Security Controller be
powered by the approved NPB-PWR-UN-H/U, regulated
15Vdc power source. For related information, see
"Estimating Power and Battery Requirements," page 6.
CAUTION
Door strike power, as well as power for other
loads switched by the security controller and/
or its expansion modules, should always be
provided from a different source.
Do not apply power to the security controller
until all other mounting and wiring is
completed. See "Power Up and Initial
Checkout," page 23.
Enclosure Power Supply
The integral power supply (NPB+PWR+UN+H/U) in a
WEBs-AX Security Enclosure (SEC-ENC-H-1/U or SEC-
ENC-H-2/U) provides 30W of regulated 15Vdc power to
an Security Controller and its connected expansion
modules, and is required for UL 294. Input voltage is
120Vac to 240Vac, single phase. You mount the Security
Controller on the top DIN rail in the enclosure, where it
connects into this power supply (see Fig. 3 on page 10). If
an SEC-ENC-H-2/U enclosure, a provided 6-wire harness
lets you connect expansion modules on the second
(lower) DIN rail.

POWER UP AND INITIAL
CHECKOUT
Ensure power wiring to the Security Controller is ready—
see "Power Wiring," page 23. Refer to Fig. 4 on page 11
for the locations of the NiMH battery connector, status
LEDs, and 4-position connector for 12V sealed lead acid
backup battery(ies).
Following all mounting and wiring, perform the
following:
1. Connect the Backup Batteries.
2. Apply Power.
3. Check the Status LEDs.
Connect the Backup Batteries
For background details, see "About the Backup Batteries,"
page 24. Make the following battery connections:
• Connect the NiMH Battery
• Connect the Backup Battery
Connect the NiMH Battery
With the cover removed from the Security Controller,
locate the red and black wires coming from the NiMH
battery pack, with 2-position connector plug. Insert the
plug into the battery connector on the bottom board (near
option slot 2 area), as shown in the figure below.
