01 GENERAL
01.01 This
section describes the
instsJl&tion procedures neeessary to
ensui'e proper operation of foe S flt.~ r A
Vl system.
02 PACKING
02.01 When a STRATA Vl system is
received, examine <'tli packages and
make careful note of anv visihle
damage. !f any darMge is fo~nd, bring
it to the attention of the delivery
carrier and make the proper claims.
02.02 Cheek

slip. If it is determined that equipment
is m1ssmg, contact your supplier
immediately,
02.l.l3 After
installation is
equipment for
i::; detected,
immediately.
unpneking (before the
started), inspect till
damage. If any damage
contact your supplier
02.04
When packing or storing the
CfWll
and/or MCCU, ensure the
following:
e. Do not use plastic or any type of
conductive material for packing
either the CRDU or the MCCU.
o Use plain paper.
NOTE:
Conductive packing material
may cause the internal back-
up battery to discharge and
damage the system.
02.05 When installing or removing
the CRDU PCB from the vlCCC PCB,
do not touch the back side (soldered
side)
of either PCB. Hold the PCB by
the edge whenever handling it.
02.(16
Whenever storing or shipping
SECTION 100-006-200
INSTALI.J\TION
the MCCU and/or CRDU, always ensure
that the battery strap is in the OFF
position (Figure 1).
St\3. !JAlTt:HY ~! l{/,P
"
FIGURE l
NOTE:
Always make sure the battery
strap( s) an the MCCU and far
CRDU is in the "ON" position
just prior to installation.
If not, the SET LED on the
MCCU will not operate.
03 MKSU LOCATION REQUIREMENTS
O:Ull Power Requirements
03.02 rhe STRATA VI .\1KSU
requires 24 VDC. This ls provided by
the EPSA, .vhich in turn requires power
from a grounded 115 VAC outlet. The
outlet should be ..c;eparately fused and
rated at 15 ornps.
03.03 The 5·Hnch cord provided to
cormect the EPS,\ to the :VlKS!J
dictates the reli1tive locstion of the
EPSA. The EPSA i5 also equipped with
a 10-ft. AC power cord.
03.10 Ventilation Requirements
os.n
Sufficient ventilation should
- 1 -

SECTION 100-006-200
INSTALLATION
exist to allow the dissipation of heat
generated by the power supply and
MKSU.
03.20 Environmental Factors
03~21 Humidity at the MI\SU loca-
tion should be within 2!HW% (without
condensation), and the temperature
should be relatively constant >Vithin a
range of 0-50° c. Exposure to dust
awl airborne chemicals should also be
taken into consideration.
tl3.31 The MKSU must be located so
thnt all stations are within 1000 cable
feet of it. Ae0eptable cable is 22 or
24 AWG inside telephone station cable,
jacketed but not shielded, having two
or more wire pairs.
04 MKSU MOUNTING
04.01 The MKSU is designed for
either table or wall mounting, but
comes from the factory configured for
table mounting. For wall mounting
instructions, refer to Paragraph 04.20.
04.lll Table Moo.ntmg the MKSU
04*11 Since the :vrn:su is tllready
configured for table mounting, the only
retJuirement is
to choose a suitable
location and proceed to Section
100-0 0 6-2 50' .'.; ... :: .. :.: ::.: .. ....:~=x::.;.. .:.:;.:;:.:.:~:.::.:.·:.:~:::
04.21 Prepare the MKSU for wall
mounting by reversing the back cover
to expose the two top mounting holes.
Proceed as follows;
o Remove and save the five screws
securing the back cover.
o Rotate the back cover um
0, and
realign it so the flanges with the
two mounting holes projeet above
the top of the '<1!\SU, os shown in
Figure 2.
o Reinstall the back eover, and
s(;eure it
with the fivs screws that
were removed earlier.
FIGURE 2
04.22 Secure the ;vl!\SlJ, as shown
in Figures 2 and 3, with fasteners
through the upper
two holes and the
single lower hole in the backplate.
The fasteners should be either 1/4-ineh
molly screws, bolts, or lag
screws, depending upon the type of
wall surface used.

08.11 An optional handset hanger
• kit
is required to convert either type
of EKT for wall mounting. The EKT
may be mounted on a wall or any other
flat, vertical surface to which the base
can be secured.
08.U When selecting the mounting
site, consider the EKT weight and the
additional stresses to which the
mounting will be subjeeted.
08.13 Mounting screws or mollies,
appropriate for the surface
on whieh
the telephone is to be seeured, must be
provided by the installer.
08.14 Locking tabs
secure the base
to the EKT. The direction in which
the base is attached to the BKT de-
termines whethe.r 1t will be used as a
desk unit or wall unit (it is factory-
configured as a desk unit). Disengage
the locking tabs (A & B, Figure 20) by
pushing downward on the base. Refer
to Figure 19, choose which of the two
lower choices is appropriate, and cut
the holes through which the tail cord
will be routed.
FIGURE 19
08.15 Secure the base to the de-
sired wall site. Use a spirit level and
make certain the top of the base is
level and that the deeper portion is
down.
08.16 Route the tail cord through
the holes
in the base and secure the
EKT (Figure 20).
Test the sturdiness
of the EKT mounting.

09 SYSTEM POWER-UP INITIAUZE
09.Gl The STHATA Vl has a list of
standi!rd system dnta assignments stored
in ROM that can be entered at any
time by activating the SET switch on
the :vlCCU PCB. The system must be
initialized when it is first installed or
whenever the iVJCCU PCB is chnnged.
This will allow the system to be tested
and any ftlults to be correded before
time is spent on programming.

MTOU PCB is in the ON position.
b) Hold in the INT switch on the

SET switch and allow it to lock.
Depress and release the SET switct1
again.
e) Reloase the INT switch.

09.H.I The Automatic Dialing memory
will contain random numbers when the
system is powered up initially. To
clear the memory; therefore, preventing
meaningless numbers from being dialed,
proceed as follows:
