01 GENERAL
01.01 The MPSA-200 is equipped
with a reversible, built-in bracket (Fig-
ure 1); it is configured at the factory
FIGURE l
for mounting on a wall or other ver-
tical surface. In order to mount on a
table or horizontal surface securely,
the bracket must be reversed to the
position shown in Figure 2. This orien-
tation is necessary to assure proper
cooling.

amine the package and make careful
note of any visible damage. If any
damage is found, bring it to the atten-
tion of the delivery carrier and make
the proper claims.
01.03 Check the hardware list; if it
is determined that any equipment within
the carton is rmssing, contact your
Toshiba
supplier immediately.
01.04 The following hardware, which
is required to mount and connect the
MPSA to the system, is supplied with
each unit.

location. If on a wall, use a spirit
level to verify that the drilling points
are level.
01.12 Place punch marks on the
mounting surface through the two rr+rr
marks on the template.
01.13 Drill through the mounting
surface with a 5/16-inch bit to prepare
the anchoring holes.
01.20 Mounting the MPSA
01.21 Press the anchor legs of the
togglers together, and insert them into
the anchoring holes (Figure 4) until
their neck flanges are flush with the
mounting surface. If insertion is diffi-
cult, tap them lightly with a hammer.

01.25 Position the power supply so
that the narrower portions of the holes
slip
over the screws, and (if the unit is ·
wall-mounted) the weight of the power
supply is supported. Tighten the screws.
01.26 If the power supply is tab-
le-mounted, make certain the unit rests
on its four rubber rrf eetrr and is secured
with the mounting bracket. This is es-
sential for proper cooling.

01.30 Fuses
01.31 Remove the spare fuses from
the hardware carton, and place them in
their individually marked holders.
01.32 Remove and inspect the fuses
that were shipped inside the MPSA. If
either fuse is defective, replace it and
order another spare fuse from your
Toshiba supplier.
01.33 Prior to installing the PBBU,
connect the MPSA to the MKSU per
Paragraph 06.10, Section 100-006-200,
Installation.
02 BATTERY BACK-UP INSTALLAT1:0N
02.01 The power battery back-up
unit (PBBU) in Figure 8 is an optional
PCB which may be installed in the
MPSA-200 to interface with two aux-
iliary 12-VDC 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 some time (in direct
ratio with the type and size of the
batteries chosen).
FIGURE B
02.02 The PBBU contains a voltage
sensing circuit which causes an elec-
tro-mechanical relay to connect the
back-up battery power to the system
-3-

before the Nl PSA output voltage drops
below 21-VDC (at which point system
functions would be disrupted and
existing calls would be disconnected).
02.03 When the normal source of
electrical power is restored, the volt-
age sensing circuit relay will disconnect
the standby battery power source.
02.04 If the standby battery power
source output falls below 21-VDC while
it is connected to the system, the volt-
age sensing circuit will cause the relay
to disconnect the standby batteries
from the system.
02.05 The standby batteries will not
be reconnected unless:
• The "Battery Override
11
switch (Fig-
ures 8 and 9) is placed in the ON
position, or ...
• The
depleted batteries are re-
placed by a freshly charged pair
and the
11
Battery Override
11
switch
is turned on and then released.
02.06 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 ba tterv
output terminal connections. -

e Two Batteries-lend-acid, mainten-
ance-free automobile batteries (80

ded. The procedures in Paragraph
02.40 assume batteries with sidc-
mounted terminals are used.
e Battery Rack & Separntor-a bat-
tery rack and separator should be
used
to assure the batteries will
not tip and spill battery acicl or
accidentally shot't the ba ttet'y ter-
minals.

1/8-in. spade tet'minals, is required
to connect the batteries and the
MPSA. The minimum wire gauge
must be determined by the loop
length of the connecting cable (as
indicated in Table A).

e Single-Wire Cable-a 16 AWG sin-

• Cable Clamp-a cable clamp should
be used to
prevent cable movement
from
affecting the batteries.
• Battery Protection-a 10-amp, 32V
fuse, or a 10-amp DC instantan-
eous-tripping cir cuit breaker, is
required to protect the batteries
from power surge or short circuit
damage.
• Bolts-four 3/Sxl/2-in. 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 cabi-
net is required to safeguard them.
CAUTION:
The power supply, battery,
battery rack, and the inter-
connecting wiring shall be
installed only by qualified
installers, in accordance
with all applicable electri-
cal codes and Article 480 of
the National Electrical Code.
Before installing see the
"Installation Instructions"
enclosed with each item.
WARNING:
Only trained personnel may
service or install the PBBU
and power supply.
