7. 
INSTALL THEEXPANSION PCB INTO THE KSU 
7.01 The Main Control PCB has circuitry for 3 C.O. lines and 8 
keysets. 
The Expansion PCB adds circuitry for 3 C.O. lines and 
4 keysets, completing the 6 X 12 configuration. 
NOTE: If you are adding the Expansion PCB after the system has 
been installed, turn off the KSU AC power switch (PWR), unplug 
the KSU AC power cord, and unplug the 25-pair station cable and 
C.O. 
line cords from the KSU. 
Remove the KSU from the wall and 
open it 
(1) according to the instructions on the previous page. 
Remove the four screws holding the Main Control PCB to 
the KSU housing. Handle PCBs by the edges only. 
contain static-sensitive components. They 
(2) Carefully lift the PCB, turn it over, and hold it by the 
edges. Take care not to dislodge any of the wires that 
connect the components to the switches or connectors. 
(3) With the solder sides of the two PCBs facing each other, 
carefully insert the Expansion PCBs seven 8-pin con- 
nectors and the five stand-offs into the corresponding 
sockets and holes on the Main Control PCB as shown in 
Figure 3-8 on the next page. 
(4) To ensure that the Expansion PCB is properly seated, 
press firmly on the back of each connector and stand-off. 
(5) Carefully turn the Main Control PCB over and return it to 
its original position in the KSU housing. 
Replace the 
four screws. 
(6) Replace the KSU cover and the four retaining screws. 
8. 
MOUNT THE KSU 
(1) Refer to Figure 3-9 on the next page. 
On a large sheet 
of paper, trace the outline of the back of the KSU and 
the two mounting screw holes. 
(2) Transfer the mounting hole markings to the MDF backboard 
where the KSU will be positioned. 
(3) Drive a #8 pan-head screw into the center of each mark- 
ing, allowing the head of the screw to protrude l/4 to 
l/2 inch (0.6 to 1.2 centimeters). 
(4) Hang the KSU on the screws. 
Adjust the screws if neces- 
sary to ensure that the KSU is securely mounted.

9. COMPLETE ALL CONNECTIONS FOR THE RSU 
(1) Attach the female connector that is on the 25-pair cable 
on the station block to the male connector on the left 
side of the KSU. 
This completes the keyset connections. 
(2) To complete C.O. line connections from the modular jack 
assemblies mounted next to the KSU, plug the loose end of 
each line cord into the corresponding C.O. jack on the 
KSU. 
Remember, the first jack connects lines 1 and 2, 
the second jack connects lines 3 and 4, and the third 
jack connects lines 5 and 6. 
(3) Plug the recommended surge/spike protector into the des- 
ignated AC outlet. Then plug the KSU AC power cord into 
the protector. (Specifications for the protector are on 
page 2-12.) 
(4) Turn the AC power switch (PWR) to the ON position.

10. INSTALL THE KEYSETS 
10.01 Ensure that the station loop resistance test has been per- 
formed before installing the keysets. 
(1) Unpack and inspect each keyset for damage. Along with 
the keyset, the box should contain a 6-foot line cord, a 
coiled handset cord, a handset, and a plastic bag of key 
designation tabs. If items are missing or damaged, con- 
tact Inter-Tels Order Processing Department. 
.:1. 
(2) With KSU AC power on, check the voltage on each modular 
jack assembly as follows: 
a. 
b. Measure the voltage on the BLACK (+28) terminal with 
respect to the YELLOW (GND) terminal. 
(Place the 
common probe of the voltmeter on the YELLOW terminal.) 
It must measure +28 +GVDC. If -28VDC is measured, 
check the cabling for a reversed pair. 
Check that there is no voltage across the other pair 
(on the GREEN and RED terminals). 
If there is volt- 
age, trace the wires back to the KSU and correct the 
problem. 
**************t****************************************** 
* 
CAUTION * 
* Incorrect voltage polarity will result in a blown * 
* fuse if the keyset is connected, which affects the * 
* operation of other keysets connected to the KSU. * 
*********************************************~*********** 
(3) After testing all modular jack assemblies, turn the KSU 
AC power switch (PWR) to the OFF position to avoid short- 
ing components while mounting the jack assemblies in the 
next step. 
(4) For each keyset: 
a. Mount the jack assembly on the wall. 
b. Plug one end of the keyset line cord into the jack 
assembly. Plug the other end into the keyset jack 
labeled KSU. 
c. Plug one end of the coiled handset cord into the jack 
on the left side of the keyset. 
Plug the other end 
into the handset. 
(5) After all keysets are installed, turn the KSU AC power 
switch (PWR) to the ON position. 
‘! :: I 1.: 
(6) After the system has been programmed, check that the key- 
sets function properly.

10.02 Optional, keyset equipment: Three optional items can be 
connected to keysets. For information about a headset, refer to 
page 2-12. A data device equipped with a direct-connection modem 
can be connected to an Executive Keyset; refer to page 7-13. 
Refer to page 3-20 for information about a handset amplifier. 
10.03 To wall mount the keysets: 
(1) 
(2) 
(3) 
(4) 
(5) 
(6) Remove the keyset baseplate by pressing down on the bot- 
tom edge of the baseplate and pulling it off. Set the 
keyset aside. 
Reverse the baseplate so that the mounting holes are at 
the top. Position the plate in the desired location on 
the wall. 
Mark the location of the keyset mounting holes on the 
wall. Set the baseplate aside. 
Drive a #8 pan-head screw (or proper hardware for the 
wall) into the center of each mounting hole marking. 
The 
head of the screw should protrude approximately l/4 to 
l/2 inch (0.6 to 1.2 centimeters). 
Replace the baseplate on the keyset with the mounting 
holes toward the top. 
Mount the keyset on the wall. 
Adjust the screws if 
necessary to ensure that the keyset is securely mounted.

11. INSTALL lj HANDSET AMPLIFIER 
11.01 
Users may request to have a handset amplifier installed to 
be able to adjust the volume of the receiver. Refer to page 2-12 
for specifications. Install the amplifier as follows: 
(1) Unplug the coiled handset cord from the keyset. 
(2) Plug the coiled handset cord into the amplifier jack 
labeled HANDSET. 
(3) Plug the amplifier line cord (coming from the jack 
labeled TELEPHONE) into the keyset handset jack. 
(4) Plug the amplifier power supply cord into an AC outlet. 
(5) The handset receiver volume can be increased or de- 
creased, using the thumbwheel located on the amplifier. 
Verify that the amplifier is functioning correctly by 
placing a call and adjusting the volume from low to high. 
12. CONNECT THE EXTERNAL MUSIC SOURCE 
12.01 
A jack on the right side of the KSU is the input for the 
optional external music source (radio, tape player, etc.). 
If a 
radio is being used, an external antenna is recommended to pre- 
vent station drift. Refer to Figure 3-12 on the next page. 
NOTE: The music source should be placed 5 to 10 feet (1.5 to 3.0 
meters) 
(1) 
(2) 
(3) 
(4) 
(5) away from the KSU to avoid interference. 
Attach the RCA-type phono plug to one end of a 5- to lo- 
foot (1.5- to 3.0-meter) length of coaxial cable. 
EITHER, connect the other end of the cable to the speaker 
output terminals of the music source. 
OR, attach a l/8-inch mini-phone plug to the other end of 
the cable, and plug it into the earphone jack of the 
music source- 
Insert the phono plug into the KSU jack labeled MUSIC. 
:; ,:. 
Plug in the AC power cord for the music source. DO NOT 
use the outlet for the KSU. 
Turn on the AC power to the music source. 
From a keyset, 
select a C.0 line and dial the telephone number of one of 
the other lines to call back into the system. 
Put the 
call on hold to hear the music. 
Adjust the volume on the 
music source to the desired level. The optimum input 
level is l.OVRMS.

INSTALL BATTERY BACK-UP EQUIPMENT 
14.01 There are three options for installing battery back-up on 
the GLX System, as described on page 2-13. 
14.02 BATTERIES MUST BE FULLY CHARGED AND OF TEE SAHE AMP-HOUR 
RATING AND AGE. 
Since batteries give off explosive and corrosive 
gases, place them in a well-ventilated room and coat the termi- 
nals with an anti-corrosive agent. Check with your back-up power 
~ 
representative to ensure that the batteries and charger are com- 
patible.
