Toshiba Strata VI Installation Instructions Manual page 5

SECTION 100-006-200
INSTALLATION INSTRUCTIONS
DECEMBER 1982
• The EPSA-104 is necessary if four
or more BLF EKTs are required
within a system. Up to 16 BLF
EKTs may be installed with an
EPSA-104 power supply.
03.04 The 54-inch cord provided to
connect the power supply to the MKSU
dictates the relative location of the
power supply. The power supply is also
equipped with a 10-ft. AC power cord.
03.05 Optional battery back-up units
(PBBU) are available for both power
supplies. The PBBU is a printed circuit
board that mounts inside the power
supply housing. The recommended bat-
tery pack, which is customer supplied,
consists of two 12VDC batteries (main-
tenance-free automobile-type is recom-
mended). With the optional battery
back-up assembly installed, all functions
of the STRATA VI system will operate
for a period of time (which is in direct
ratio with the type and size of bat-
teries selected) after a loss of normal
electrical power. No calls will be dis-
connected during switch-over to bat-
tery power.
03.10
Ventilation Requirements
03.11 Sufficient ventilation should
exist to allow the dissipation of heat
generated by the power supply and
MKSU.
03.20
Environmental Factors
03.21 Humidity at the MKSU loca-
tion should be within 20 "'--' 80
%
(without
condensation), and the temperature
should be relatively constant within a
range of O""'-' 50° C. Exposure to dust
and airborne chemicals should also be
taken into consideration.
03.30 Cabling Considerations
03.31 The MKSU must be located so
that all stations are within 1000 cable
feet of it. Acceptable cable is 22 or
24 A WG 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, ref er to Paragraph 04.20.
04.10 Table Mounting the MKSU
04.11 Since the MKSU is already
configured for table mounting, the only
requirement is to choose a suitable loc-
ation and proceed to Section 100-006-
250, MPSA-200 Installation or Section
100-006-255, EPSA-104 Installation.
04.20 Wall Mounting the MKSU
04.21 Prepare the MKSU for wall
mounting by reversing the back cover
to expose the two top mounting holes.
Proceed as follows:
• Remove and save the five screws
securing the back cover.
• Rotate the back cover 180°, and
realign it so that the flanges with
the two mounting holes project
above the top of the MKSU, as
shown in Figure 2.
