Installation Test Procedures 
issue 1. May 1986 
3.01 General. The SATURN HE System must be connected 
to an earth ground (i.e., metallic cold water pipe or master ground 
busbar) in addition to the safety ground in the ac power cord. 
A G-gauge (twisted copper wire) conductor should be connect- 
ed between the grounding lug E5 located on the bottom of the 
cabinet frame and the snlccted earth ground (refer to Section 
3.00 in the SATURN HE EPABX Installation Procedures prac- 
tice for details). The following tests must be performed to en- 
sure that proper earth ground connections have been 
accomplished, and that ground connections within the cabinet 
assembly have not been damaged or loosened during shipment.

3.03 Shelf Ground Continuity Test. Each LTU shelf assem- 
bly within the cabinet assembly is grounded via two vertical 
busbars. Beiore proceeding with the test procedures indicat- 
ed in Table 3.01, check that each shelf backplane is iniercon- 
netted with the busbar flanges and adequately secured into 
position.

SECTION 4.00 POWER-UP TESTS 
4.01 General. The SATURN IIE System makes use of dis- 
tributed power in the equipment cabinet. Several power sup- 
plies are used in the system. These power supplies provide 
+5Vdc, -SVdc, +12Vdc, -12Vdc, -48Vdc, 90Vac-20Hz ringing 
voltage and message waiting voltage, from a 11OVac 60Hz 
input power source. After satisfactorily performing the ground 
tests indicaied in Section 3.00, the following 
tests must be per- 
formed to ensure that proper power cable connections have 
been accomplished and that the power supplies inside the 
cabinet assembly have not been damaged during shipment. WARNING 
Hazardous voltages exist within the equipment cabinet. Be 
extremely careful when performing testin@roubkshootjng’ 
pmcedures with the equipment panel(s) removed. 
4.02 Power-Up/Output Voltage Tests. Before proceeding with 
the test procedures indicated in Table 4.00, check that all pow- 
er cable assemblies are properly secured into their correspond- 
ing locations. Note that the test procedures in Table 4.00 include 
procedures for testing the optional MSM, when equipped in the 
system. 
Table 4.60 Power-Up/Output Voltage Test 
YiEP PROCEDtJRE 
f not previously done, extract each 
‘CB in the system from its respec- 
ive backplane connector in basic 
md LTU shelves. 
Check that 
all circuit breakers on the 
‘SU are in the off positions and that 
311 fuses are inserted in their cor- 
,esponding locations. 
Jsing the digital multimeter (or an 
3c polarity indicator), verify that the 
:ommercial ac power receptacle 
Jsed for powering the systsm has the 
Iroper polarity. 
Connect the 
ac power cord(s) to the 
zommercial ac power receptacle(s). 
?lace the following circuit breakers 
on the PSU to the on (up) position: 
a) Basic PS 
b) -48PSO 
c) -48PSl (if equipped) 
d) LTUPSO (if equipped) 
e) LTUPSl (if equipped) 
9 LTUPS2 (if equipped) 
If the optional MSM module is 
equipped in the system, proceed 
2s follows: 
2) If not previously done, connect 
and insert battery pack into 
the MSM assembly. 
b)Press the BATTERY TEST 
switch on the PSU and 
release after verification has 
been obtained. VERIFICATION 
‘olarity indication must coincide with 
=igures 3.00 and 3.01. 
The associated green LED should 
light steadily. IF VERIFICATION 
IS NOT 08TAlNED 
if polarity indication does not coin- 
cide, correct before proceeding with 
the remainder of test in this lable. 
If the green LED remains cxtin- 
guished, the battery pack is below 
acceptable voltage limits. Let MSM 
charge battery pack and retry test af- 
ter 30 minutes have elapsed. If green 
LED remains extinguished, the bat- 
tery pack is defective and requires 
replacement.
