Note: Unit is equipped with two (2) 1A max. auxiliary outputs: “AUX1” will automatically disconnect when
AC is lost. “AUX2” will remain battery backed up during power outage. For loads connected to “AUX2”
please, refer to battery “Stand-by Specifications” above for ratings. When loads are connected to 10A
total alarm current (example: AUX1 = 1A, AUX2 = 1A, outputs up to 8A).
Installing R1042ULADA into Rack Tower:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/ANSI, and with all local codes
and authorities having jurisdiction. Product is intended for indoor use only.
Note:
First assemble and install Z Bracket Wire Management Accesory
(refer to Z Bracket Installation pg. 4)
Note:
Rack enclosure must be UL listed and hard wired to a branch electrical circuit via conduit
1. Remove backplane from enclosure prior to installing into rack cabinet
(do not discard hardware).
Grounding:
Connect both grounding lugs
(Fig. 1)
to earth ground using 12 AWG wire.
2. In order to mount included UL Listed tamper switch (Altronix Model TS112
or equivalent) turn the enclosure upside down. Punch out the knockout in
designated location, on the back of the unit, from outside of the drawer
(Fig. 2, pg. 3)
. Insert the tamper switch into the knockout from outside of the
drawer with the button facing outwards and spaded connectors inside the drawer.
Connect tamper switch wiring to the Access Control Panel input or the
appropriate UL Listed reporting device. To activate alarm signal open
the rack drawer.
3. Slide the rack enclosure into an open 2U location in the four post rack cabinet.
Intended for indoor use in properly ventilated racks with ambient temperature
inside the rack not to exceed 33ºC. Allow approx. 1” of spacing between units
or other equipment.
4. Utilizing proper fasteners attach front ears to the rack rails
(Rack Drawer, pg. 20)
.
5. Attach the rear of the adjustable slides to the rear rails of the rack cabinet with
the proper fasteners.
6. Ensure that all internal cofigurations (voltage selection, switch settings, etc.) are
completed before mounting backplane back into rack enclosure.
