01 GENERAL 
01 .Ol This section describes the installation 
procedures necessary to ensure proper opera- 
tion of the 
Strata V/e system. 
02 PACKING 
02.00 Inspection 
02.01 When a Strata V/e system is 
received, examine all packages and carefully 
note any visible damage. If any damage is 
found, bring it to the attention of the delivery 
carrier and make the proper claims. 
02.02 Check the number of cartons and the 
contents of the 
Strata We shipment 
against the purchase order and packing slip. If 
it is determined that any cartons are missing, 
contact your delivery carrier immediately. If it 
is determined that any equipment within a car- 
ton is missing, contact your Toshiba supplier 
immediately. 
02.03 After unpacking (prior to beginning 
the installation), inspect all equipment for 
damage. If any damage is detected, contact 
your delivery carrier immediately. If possible, 
retain all the original packing material. 
CAUTION! 
When handling (installing, removing, 
examining, etc.) a printed circuit board, 
do not touch the back (soldered) side or 
the pin connector. Always hold a PCB 
by its edge. 
02.04 
When packing or storing a VCCU, 
ensure the following: 
l Do not use plastic or any type of conduc- 
tive material for packing a VCCU. Use plain 
paper. 
CAUTION! 
Conductive packing material may cause 
the internal back-up battery to discharge 
and damage the PCB. 
02.05 
Whenever storing or shipping a 
VCCU, always ensure that the battery strap is 
in the 
OFF position (see Figure 1).

HKSU REQUIREMENTS 
03.00 Power Requirements 
03.01 
The Strata V/e HKSU requires 24 
-l- 
FIGURE 1 -VCCU BATTERY STRAP 
e 
VDC. This is provided by the internal power 
supply (HPSU 7120), which in turn requires 
power from a grounded 115 VAC outlet. The 
outlet should be separately fused and rated at 
15 amps. 
03.02 An optional battery back-up unit 
(HPBU-7) is available for the HPSU 7120. With 
the optional battery assembly installed, all 
functions of the 
Strata V/e system will 
continue to operate for approximately 2 l/2 
hours after a loss of normal electrical power. 
No calls will be disconnected during switch- 
over to battery power. 
03.10 Ventilation Requirements 
03.11 
Sufficient ventilation should exist to 
allow dissipation of the heat generated by the 
power supply and HKSU. 
03.20 
Environmental Factors 
03.21 
Humidity at the HKSU location should 
be within 20 - 80% (without condensation), 
and the temperature should be relatively con- 
stant within a range of 32 - 122O F (0 
- 50° 
C). Exposure to dust and airborne chemicals 
should also be taken into consideration. 
03.30 
Cabling Considerations 
03.31 
The HKSU must be located so that all 
stations are within 1,000 cable feet (305 M) of 
it. Acceptable cable is 22 or 24 AWG inside

shielded), having two or more twisted wire 
pairs. 
04 HKSU INSTALLATION 
04.00 Wall Mounting the HKSU 
04.01 To mount the HKSU on the wall, per- 
form the following steps: 
1) Remove both side covers from the HKSU 
(refer to Figure 2) by pressing in on the two 
small ribbed sections on each side cover to 
free the holders. 
FIGURE 2-HKSU SIDE COVERS 
2) Hold the HKSU against the wall in its 
planned location and mark the screw locations 
through the centers of the two keyholes on the 
upper sides of the HKSU. 
3) Lay the HKSU aside for the moment and 
start two screws into the wall at the marked 
locations. Use 1 l/4” panhead wood screws 
and stop when they have penetrated to half 
their depth. 
4) Hang the HKSU on the two screws and 
start two additional screws in the lower two 
holes. Tighten all four screws. 
5) Knockouts are provided on the top and bot- 
tom of the side covers to permit cables to enter 
the HKSU. Kemove the appropriate knockouts. 
6) Reinstall the side covers. 7) A completed installation should appear as 
hown in Figure 3.

							VMAU: The main PC6 of the HKSU provides 
the following three functions: 
a) 
Station Interface-An interface between 
the HKSU and up to eight EKTs, which 
includes the solid-state space division 
matrix used for voice connections between 
the EKTs and the CO/PBX lines. Two-pair 
wiring is required for each EKT; one pair 
carrying voice and the other pair carrying 
control data to and from the EKT. 
b) CO Interface-An interface between the 
HKSU and the public telephone network or 
PBX for three lines. Ring detection, hold and 
dial outpulsing for the three lines are per- 
formed by this PCB. Depending upon local 
CO requirements, the VMAU is programmed 
to provide DTMF or rotary dial outpulsing. 
c) Tone-Performs a number of miscellane- 
ous system functions: 
l Generates system tones. 
l Provides switching matrix for tone deliv- 
ery of paging and intercom connections. 
l Houses interface for the external page. 
VCOU: An optional interface between the 
6,. -47 
VMAU and three additional public telephone 
network or PBX lines. Depending upon local 
CO requirements, the VCOU is programmed 
to provide DTMF or rotary dial outpulsing 
(serves up to three CO/PBX lines). 
SSTU: An optional interface between the 
HKSU and stations 18 
- 21 and/or 22 - 25. 
Each SSTU PCB serves up to four EKTs. 
Two-pair wiring is required for each EKT; 
one pair carrying voice and the other pair 
carrying control data to and from the EKT. 
VCCU: All system control functions are per- 
formed by the singlechip microprocessor on 
this PCB. The system program stored in 
ROM, the RAM for system operations, and 
the RAM for system data storage are also 
located on this circuit board. 
SMOU: An optional .music-on-hold source 
that provides electronic synthesized music. 
It is connected to the VMAU via a 7-pin 
connector. 
SEPU: An optional 3-watt amplifier for exter- 
nal paging. The SEPU is attached to the left 
side panel of the HKSU and connected to 
the VMAU via one 1 O-pin connector.

MAY 1986 
04.20 Power Supply 
04.21 
The system requires 24 VDC, which is 
provided by the internal, factory-installed 
power supply (HPSU). The HPSU requires 115 
VAC, 60 Hz, with a permissible AC input volt- 
age range of 90 - 130 VAC. 
04.22 An optional battery back-up unit 
(HPBU-7) is available. It is a PCB that mounts 
inside the power supply housing (Figure 5) and 
is connected to the female 3-prong connector 
inside the power SUPP~Y’S case. Secure the 
, 
i /  /

FIGURE 5-HPBU INSTALLATION 
04.23 The HPBU is then connected via the 
terminal block to the recommended battery 
pack (which is customer-supplied, consisting 
of two 12 VDC, maintenance-free, automobile- 
type batteries-80 amp/hour maximum 
rating). With the optional battery back-up 
assembly installed, all functions of the system 
will continue to operate for several hours (the 
actual time period is in direct ratio to the type 
and size of batteries selected). 
04.24 The Toshiba 
Strata V/e electronic 
key telephone system requires a solid earth 
ground. Failure to provide such a ground may 
lead to confusing trouble symptoms in the sys-

tern and, in extreme cases, circuit board fail- 
ure. In most installations (within the continen- 
tal United States), the ground provided by the 
“third wire ground” at the commercial power 
outlet will be satisfactory for all 
Strata V/= 
requirements. However, in a small percentage 
of installations, this ground may be installed 
incorrectly. Therefore, prior to installing a sys- 
tem, the third wire ground must be tested for 
continuity by either measuring the resistance 
between the third prong terminal (earth 
ground) and a metal cold water pipe, or by 
king a commercially available 
indicator. If neither procedure is 
the test procedures outlined 
04.30 should be performed. earth ground 
possible, then 
in Paragraph 
WARNING! 
Hazardous voltage is exposed during the 
following test. Use great care when 
working with AC voltage. 
04.30 Test 
Procedures 
1) Obtain a suitable voltmeter and set it for a 
possible reading of up to 250 VAC. 
2) Connect the meter probes between the two 
main AC voltage points on the wall outlet. The 
reading obtained should be 90 - 130 VAC. 
3) Move one of the meter probes to the third 
prong terminal (GND). Either the same reading 
or a reading of 0 volts should be obtained. 
4) If the reading is OV, leave one probe on the 
GND terminal and move the other probe to the 
second voltage terminal. If a reading of OV is 
obtained on both voltage terminals, the outlet 
is 
not properly grounded. Omit Steps 5 
through 7 and proceed directly to Step 8. 
5) If a reading of OV on one terminal and a 
reading of 90 - 130 VAC on the other terminal 
is not obtained, the outlet is 
not properly 
grounded. Omit Steps 6 and 7 and proceed 
directly to Step 8. 
6) If a reading of OV on one terminal and a 
reading of 90 - 130 VAC on the other terminal 
is obtained, remove both probes from the out- 
let. 
7) Set the meter on the “OHMWRxl” scale, 
place one probe on the GND terminal and the 
other probe on the terminal that produced a 
reading of OV. A reading of less than 1 ohm should be obtained. If a reading of more than 1 
ohm is obtained, the outlet is 
not adequately 
grounded. 
8) If the above tests show the outlet is improp- 
erly grounded, that condition should be cor- 
rected by a qualified electrician (per Article 
250 of the National Electrical Code) before the 
Strata system is connected. 
04.31 Ensure that the power switch on the 
HPSU is OFF, then plug the power supply into 
the 1 15 VAC outlet.
