Circuit protection
A thermistor c urrent-limits the maximum outp ut of eac h outp ut to 12 W, but the 
averag e p ower p er outp ut c annot exc eed  7.25 W (200/32 =  7.25). An LED 
indic ates the status of the thermistor. When the LED is ON, there is a short on the 
power pair.
Mountings
The back-up battery mounts on a top plate. The power supply and distribution 
units mount on a b ottom p late. The plates are normally wall-mounted .
Installing the Wall Mounting 
See Fig ure 3
1. Loc ate one p late d irec tly b elow the other with the raised letters rig ht sid e 
up . Be sure  that the AC p ower c ord  c an reac h the elec tric al outlet from 
the b ottom p late. The p ower c ord  is ab out 7.5 ft (2 m) long . 
NOTE:
Up  to 4 p ower sup p lies c an d raw c urrent from one 110- or 230-VAC, 
20- or 15-A feed er. Use only unswitc hed  rec ep tac les that are not 
shared  with other equip ment.
2. Sec ure the wall mounting  p lates to a 3/4-in. (2-c m) p lywood  mounting  
b oard using  the four 1/2-in. #10 wood  sc rews sup p lied  with the p lates.
3. Snap  the 1145B p ower sup ply onto the b ottom wall-mounting  p late (no 
tools are need ed ).
4. Connec t an insulated 17-AWG #12 (1.2-mm) g round  wire (or b etter) 
b etween the g round  lug  on the p ower-sup p ly frame  and  an ap p roved  
g round . 
The frame g round sc rew is loc ated  next to the AC rec ep tac le, to the left of 
the unit.

Installing the 1146 Power Distribution Unit
1. Insert and  sec urely tig hten the two sup p lied  #8-32 x 1/2-in. should er 
sc rews (they have an unthread ed  sec tion at the top ) into the top holes 
d esig nated  for 1146 Power Distrib ution Unit on the b ottom p late. Mount 
the unit on these two shoulder sc rews, using  the key holes on the b ac k of 
the unit. 
2. Sec ure the unit b y inserting  the #8-32 x 1 in. sc rew throug h the b ottom of 
the unit (just ab ove the wire c lip s) into the plate and  tig hten.
3. Set the b attery b ac k-up  switc h op tion to the 1-32 (d own) p osition to 
p rovid e b attery bac k-up  to all outp uts. 
4. Connec t the p ower d istrib ution unit to the p ower sup p ly with the p ower 
c ab le. Refer to the p ower sup ply’s rig ht-sid e lab el to loc ate the outp ut 
p ower c onnec tion.
Installing and Wiring the Battery
Two types of back-up batteries can be used:
To install the b attery, p roc eed  as follows.
1. Loosely insert two #10-32 x 1/2-in. should er sc rews in the b attery-
mounting holes at the top of the wall mounting plate.
2. Plac e the keyhole slots in the b attery b rac ket on these two sc rews. Make 
sure the lab el on the b attery is visib le. 
The b attery c ord exits from the rig ht sid e of the b rac ket. 
3. Tighten the sc rews securely.
4. Plug  the b attery c ord  into the rig ht rear rec ep tac le on the power sup p ly. 
The right-side label indicates the rear receptacle.
Installing the Expanded Power Distribution Unit
You c an install a sec ond  p ower-d istrib ution unit for add itional 8400- and  8500-
series terminals.

Powering Up and Testing AC and DC Power
When you p ower up  the unit or interrup t p ower to a unit, the unit runs an AC or 
DC self test. LEDs on the front p anel ind ic ate the status of the p ower sup p ly. The 
following table lists the LEDs. 
1. Connec t the AC p ower c ord  to the p ower sup p ly, and route the c ord  to an 
ap p rop riate AC outlet using  the c lip s p rovid ed  on the unit.
NOTE:
A maximum of four p ower sup plies c an b e p owered  from one 
d ed ic ated  110 VAC, 20-A feed er. Use only unswitc hed  rec ep tac les.
2. Start the AC test b y plug g ing  the c ord  into the outlet. 
This powers up the power supply.
3. Chec k AC op eration of the 1145B p ower sup p ly by monitoring  the LEDs:
PA S S
: GREEN and  YELLOW are b oth lit. 
FA I L
: either GREEN or YELLOW LED is not lit.
4. If the AC test failed , test the AC outlet, p ower c ord , and  c onnec tions. 
5. If the AC test failed , b ut p ower is availab le and  the AC power c ord  and  
c onnec tions are g ood , rep lac e the p ower unit.
6. Onc e the AC test p asses, ac tivate the DC b attery-b ac kup  sup ply b y 
d isc onnec ting  the AC p lug .
7. Chec k DC (b attery b ac k-up ) op eration b y monitoring  the LEDs.
PA S S
: RED and GREEN are both lit.
FA I L
: either RED or GREEN is not lit.
8. If the DC test fails, c hec k the c onnec tions. 
9. If the DC test fails b ut the c onnec tions are g ood , rep lac e the b atteries and  
retest.
10. If the DC test fails after you rep lac e the b atteries, rep lac e the p ower 
supply.
11. Onc e the DC test p asses, rec onnec t AC p ower to the p ower sup p ly.

LED Color  Meaning
GREEN Power supply is providing power
YELLOW Battery is c harg ing  (after at most 20 hours, when the b attery has 
reac hed  full c harge, the YELLOW LED should  g o out)
RED Power sup p ly is on b attery reserve

Wire the 1146 Power Distribution Unit
Wire end points to the 1146 while p ower from the 1145B is on. 
1. Install c ross-c onnec t jump ers (the lab el shows p olarity) to Pins 7 and  8 of 
the ap p rop riate information outlet. Route the wires throug h the c lip  
p rovid ed on the unit. If a red  LED is on, see ‘‘Rep airing  Short Circ uits and  
Resetting  Red  LEDs’’ on p ag e 16. Fi g u re  5 shows the c onnec tions.
A red  LED lig hts if the assoc iated  c irc uit is c onnec ted  to shorted  wiring or  
a shorted  terminal.

Replacing the Batteries
To maintain back-up protection and battery reliability:
1. Rep lac e b atteries every four years.
Storing the Batteries in Inactive Units
To p revent leakag e when the p ower unit is not in use for several months or more:
1. Remove the b atteries and  store them sep arately.
Repairing Short Circuits and Resetting Red LEDs
A red  LED next to any of the 32 p ower output c onnec tors ind ic ates a short c irc uit 
in the b uild ing wiring  or the terminal eq uip ment. To reset the LED:
1. Disc onnec t the terminal eq uip ment from the wall jac k.
2. If the LED g oes off, the terminal eq uip ment is faulty. Rep lac e it. 
3. If the LED is still lit, find  and  rep air the short c irc uit in the b uild ing wiring .
4. Rec onnec t the terminal eq uipment to the wall jac k, and re-test.
