Plug the power supply into a 115 VAC outlet and check its output voltage to be sure it is between 23.2 - 28.2 VDC. If the voltage is not within these limits, replace the power supply before proceeding.

IMPORTANT:

On the MPSA-512, verify that the power

switch is ON-it will be illuminated

08.02 Disconnnect the power supply from the

115 VAC outlet. Remove the plastic protective

cover from the power terminal strip on the MKSU

left side panel, and, with the supplied cord, connect the “+24V”, “OV” and “G” terminals on the power supply to the corresponding terminals on the MKSU. Secure the DC cord to the MKSU using the plastic cable clamp provided.

08.03 The Toshiba Strata S electronic key telephone system requires a solid earth ground on the “E” terminal on the MKSU left side panel.

Failure to provide such a ground may lead to confusing trouble symptoms in the system and, in extreme cases, circuit board failure. In most instal-

lations, within the continental United States, the ground provided by the “third wire ground” at the commercial power outlet will be satisfactory for all

Strata S requirements. However, in a small percentage of installations this ground may be

installed incorrectly. Therefore, prior to installing a

Strata S system, the third wire ground must be tested for continuity by either measuring the resistance between the 3rd prong terminal (earth ground) and a metal cold water pipe, or by using a commercially available earth ground indicator. If neither procedure is possible, then the test procedures outlined in Paragraph 08.10 should be performed.

WARNING! Hazardous vottage that may cause death or injury is exposed during the following test.

Use great care when working with AC

po werline voltage.

08.10 Test Procedure

Obtain a suitable voltmeter and set it for a

.

possible reading of up to 250 VAC. Connect the meter probes between the two

main AC voltage points on the wall outlet. The

reading obtained should be 90 - 130 VAC.

Move one of the meter probes to the 3rd prong

3) terminal (GND). Either the same reading or a

reading of 0 volts should be obtained.

If the reading is OV, leave one probe on the

4) GND terminal and move the other probe to the

2nd voltage terminal. If a reading of OV is obtained on both voltage terminals, the outlet

is not

properly grounded. Omit steps 5 - 7,

and proceed directly to step 8.

If a reading of OV onone terminal and a read-

5) ing of 80 - 130 VAC on the other terminal is not obtained, the outlet is not properly

grounded. Omit steps 6 & 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 outlet.

7) Set the meter on the “OHMS/Rxl” scale,

place one probe on the GND terminal and the other probe on the terminal which produced a reading of OV. A reading of less than IS2 should be obtained. If a reading of more than

1 R is obtained, the outlet is not adequately

grounded.
