POWER WIRING

For UL 294 installations, the SEC-H-600 must be powered by the approved NPB-PWR-UN-H, 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 SEC-H-600 and/or its expansion modules,
should always be provided from a different source.
Do not apply power to the SEC-H-600 until all other mounting and wiring is completed. See "Power Up and Initial
Checkout," page 26.

Enclosure Power Supply

The integral power supply (NPB-PWR-UN-H) in a WEBs-AX Security Enclosure (SEC-ENC-H-1 or SEC-ENC-H-2) 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 11). If an SEC-ENC-H-2 enclosure, a provided 6-wire harness lets you
connect expansion modules on the second (lower) DIN rail.
