Toshiba Strata Vi Electronic Key Telephone System Installation And Maintenance Manual

							1, All models of the External 
Power Supply Assembly (EPSA) are 
equipped with a built-in wall mounting 
bracket, as shown in Figure 1, to allow 
the EPSA to be mounted on a wall or 
other flat) vertical surface.

Choose a suitable location on 
a vertical surface for the EPSA, and 
attach the P/N 117260-001 template to 
that location temporarily. Use a spirit 
level to verify that the indicated 
drilling points are level.

one of the anchoring holes, as shown in 
Figure 3. 
Insert the toggler into the 
hole until the neck flange is flush with 
the mounting surface. If it is difficult 
to insert it completely by hand, tap it 
lightly with a hammer.

Thread the #14 hex head 
sheet metal screws into the small holes 
in the center of the togglers. Leave 
approximately 3/16-inch clearance be- 
tween the bottom of each screw head 
and the mounting surface (Figure 5). Align 
the EPSA mounting 
bracket’s holes with the sheet metal 
screws as shown in Figure 6. Place 
the EPSA against the mounting surface 
with the screws protruding through the 
holes. 
Lower the EPSA so that the 
narrower portions of the holes slip over 
the screws and the weight of the EPSA 
is supported. Tighten the screws. 
Remove the spare fuses from 
the hardware carton.

Place the spare 10 amp DC 
fuse in the center fuse storage clip 
located on the side panel of the EPSA 
(Figure 6). 
Place the spare 5 amp SLO- 
BLO AC fuse in the clip below the DC 
fuse clip. 
Remove and inspect the fuses 
that were shipped inside the EPSA. If 
the visual inspection reveals a de- 
fective fuse, remove the appropriate 
spare from its storage clip and replace 
the defective fuse. (Order anot her 
spare fuse.) 
The Power Battery Back-up 
Assembly (PBBU) in Figure 7 is an 
optional PCB which may be installed in 
the EPSA 104 to interface with two 
auxiliary 12V batteries. In the event 
of an electrical power failure, the 
PBBU provides an automatic battery 
power source, permitting a typical 
STRATA VI system to continue normal 
operations for up to 12 hours.

The PBBU contains a voltage 
sensing circuit which causes an elec- 
tromechanical relay to connect the 
back-up battery power supply to the 
system before the EPSA output voltage 
drops below 21VDC (at which point 
system functions would be disrupted and 
existing calls would be disconnected). 
When the normal source of 
electrical power is restored, the volt- 
age sensing circuit relay will disconnect 
the standby battery power source. 
If the standby battery power 
source output falls below 21VDC while 
it is connected to the system, the 
voltage sensing circuit will cause the 
relay to disconnect the standby battery 
from the system. 
The standby battery’ power 
supply will not reconnect unless:

The depleted batteries are re- 
placed by a freshly charged pair 
and the “Battery Override” switch 
is turned on and then released. 
The PBBU also contains cir- 
cuitry to provide the charge current 
necessary to maintain the batteries at 
a satisfactory level of charge while the 
STRATA VI system is in normal oper- 
ation. 
An external fast charger may 
also be connected across the battery 
output terminal connections. 
The PBBU kit contains the 
following items:

PBBU-Power battery backup PCB. 
Fuse-A spare battery protection

Cable Clamp-A 
7/l 6-in e cable 
clamp which may be needed to 
secure the wiring harness inside 
the EPSA. 
“PBBU-REV 3”--An adhesive-backed 
decal to be placed on the front 
face of the EPSA. 
Warning Tag-A warning tag to be 
attached to the EPSA 115VAC 
power cord. 
In addition to those items 
supplied in the PBBIJ kit, the following 
additional items are needed to install a 
PBBU in an EPSA: Two Batteries-Two 12V/80 amp- 
hour, lead-acid, automotive-type, 
maintenance-free batteries are re- 
commended. he procedures in

with side-mounted 
terminals are 
used. 
Battery Rack and Separator-A 
battery rack and separator should 
be used to secure the batteries to 
prevent tipping and spilling of bat- 
tery acid or accidental shorting of 
the battery terminals. 
Two-Wire Connecting Cable-A 2- 
wire connecting cable terminating 
at one end with 3/8-in, ring ter- 
minals and at the other end with 
l/8-in. hooked spade terminals is 
required to provide the connection  
						

							between the batteries and 
the 
EPSA. The minimum wire size 
must be determined by the loop 
length of the connecting cable as 
indicated in Table A.

Single Wire Cable--A 16 AWG sin- 
gle wire cable, approximately 1% 
inches in length and equipped with 
ring terminals, 
is required to con- 
nect the two batteries in series. 
Cable Clamp-A cable clamp should 
be used to relieve strain on the 
battery cable to prevent cable 
movement from affecting the bat- 
teries. 
Battery Fuse-A 10 amp, 32V (min- 
imum) fuse, or a 10 amp DC in- 
stantaneous tripping circuit breaker 
is to be located adjacent to the 
batteries in series with the nega- 
tive lead of the 2-wire connecting 
cable. The battery fuse (or cir- 
cuit breaker) is required to protect 
the batteries from damage due to a 
power surge or a short circuit.. 
Hex Head Bolts-Four 3/8in. hex 
head bolts are required to connect 
the cable terminals to the batteries. 
Washers-Eight 3/8-in. flat washers 
and four 3/8-in. internal-tooth lock 
washers are required for the above 
cable terminal connections. 
Battery Cabinet-If the batteries 
are not located in a well-venti- 
lated closet or other secure area, 
protected from fire or sparks, a 
properly ventilated protective eabi- 
net is required to safeguard them. Verify that the power switch 
on the MTOU is in the 
position, 
and then disconnect the EPSA’s 115 
VAC power cord.

2. The EPSA cover is secured by 
seven screws. 
Viewing the EPSA as if 
it is wall-mounted, two screws will be 
located at the rear edge of the top of 
it, three on the side facing outward 
and two on the rear edge of the bottom. 
5 Remove all seven screws. 
Remove the cover and set it 
aside. 
Locate and trace the multi- 
wire harness in the lower portion of 
the EPSB (the 
area away from the 
built-in mounting bracket). The harness 
originates from the transformer and the 
terminals and fuse holders mounted in 
the control panel, This harness ter- 
minates in a rust-colored square eon- 
nectar. 
The harness is secured to the 
bottom of the chassis with a cable 
clamp as shown in Figure 10, Loosen 
the screw and nut slightly to allow 
movement of the harness, 
NICKEL-PLATED

Mounted in the EPSA control 
are two nickel-plated hole plugs. 
Bend in the retaining tabs on both 
plugs; remove and discard them.

The PBBU’s mounting bracket should be  
						

							flush against the rear of the control 
panel with the fuse holder and override

The 
harness should flow around the PBBU 
PCB, with no wires beneath it. 
Align the two tan-colored 
PBBU pins with the two holes in the 
heat sink (Figure 10). 
Press the pins 
into the holes until they catch and hold 
the PBBU PCB. 
Use the previously removed 
screw and secure the PBBU mounting 
bracket to the control panel. See 
Figure 11. 
Plug the rust-colored eon- 
nectar into the nine-hole jack 
center of the PBBU PCB.

jack, they are keyed so that they can 
be mated in only one position. 
Replace the EPSA cover and 
secure it with the 
seven screws 
originally removed. 
Press in the battery over- 
button (Figure 8). 
If it catches 
and stays in, press it again to cause it 
to release and protrude out of the 
control panel. Out is off, and the 
position of the button must be in for 
the EPSA to operate normally. 
Remove the spare fuse from 
the PBBU kit. If the original fuse is 
missing or defective, replace it with 
the spare. If not, put the spare fuse 
in the holder located on the side of 
the EPSA away from the control panel. 
Remove the warning tag from 
the kit and tie it to the power cord 
where it emerges from the EPSA. 
A l’PBBU-REV 3” decal must 
be placed on the control panel of the EPSA. 
Remove the decal from the kit, 
peel the backing off, and place it on 
the control panel (Figure 8). 
Select a location for the 
batteries near the EPSA. 
The loop 
length of the cable connecting them to 
the EPSA will determine the minimum 
gauge wire which can be used in the 
cable. See Table A. 
Secure the batteries in the 
battery 
rack and separator, which 
should be located in a minimum access 
area, such as a 
closet or a well 
ventilated cabinet. 
Verify that battery over- 
utton is in the 
position (out). 
Loosen the two screws on the 
terminal strip identified as 24V/BAT- 
TERY. 
Attach the cable’s two spade 
tips to these connectors. 
Each wire,  
						

							as well as the EPSA terminals, are 
marked positive (+) or negative (-). 
See Figure 12. Natch positive to 
positive and negative to negative.

circuit breaker) lead to the negative 
terminal on one battery (Figure 13).
