I ( The ES -6-l KSU is supplied with a wall mounting 
bracket. The bracket should be mounted on a back- 
board secured in a manner capable of holding the 
weight of the KSU. With the mounting tabs of the 
bracket facing upward, install appropriate screws into 
the 6 holes of the bracket. Loosen the securing screw 
located in the upper right position of the bracket. 
Align the mounting slots of the KSU with the mount- 
ing tabs of the bracket, and push down to seat the 
KSU securely. 
Remove the front cover of the KSU, and locate and 
tighten the securing .screw through the hole provided 
above the J 1 connector.

							220 Connecting and Testing the Power Supply 
Note 1: Verify that the AC outlet is supplying 11% AC 
and provides good conduit ground. If there is a 
problem with the AC voltage, have it corrected. 
If there is no conduit ground, provide alternate 
ground as explained in Section 120, “Grounding 
Requirements”, of this manual. 
Note 2: Before proceeding, ensure that the PS-6-I Power 
Cord is unplugged. The PS-6-I Power Switch 
should be off, and its power indicator lamps should 
1. 
2. Remove the 9-pin connectorended cable of the power 
supply from the connector of the KSU. 
Plug the AC cord of the power supply into an AC 
outlet. Set PSU Power switch to on position. The PSU 
Power Indicator Lamp should 
light. Use a voltmeter, 
to the figure below:

3. 
Set PSU Power Switch to Off Position 
Note: Verify that step 3 has been completed before pro- 
ceeding. Verify that PS-6-I Power Indicator Lamp 
I is off: 
4. Connect the 9-pin connectorended cable of the Power 
Supply Unit to the 9-pin connector of the KSU. Ensure 
that the looking tabs are engaged. 
5. Turn the PSU Power Switch on. DC voltage (under 
load) can now be read on the TBl terminal block 
located on the left side of KSU.

							F-- 230 Installation of KTUs 
Note: The following KTUs cannot be inserted or removed 
with power on: 
CPU-S KSI-S DPH-S 
CLK-S DCI-S PBS-S 
SWM-S 
MFI-S AHR-S 
-_. _... .._ .._ _._. - .- .__J 
230.1 General Information 
1. 
The KTUs specified directly above cannot be inserted 
or removed -with power on. It is recommended that 
power be OFF during installation and during mainte- 
nance unless this will seriously inconvenience the user. 
This will prevent accidental damage to equipment. 
The KTUs used in the Electra-616 system make ex- 
tensive use of CMOS technology. Care must be taken 
to avoid static discharge when handling these KTUs. 
KTUs are provided with a guide slot to prevent mis- 
installation. KTU connectors are provided with a guide 
key. These guide keys must not be removed. 
230.2 Installing Basic MTUs 
T 1 DC1 -S and MFI -S KTUs 
When installing DCI-S and MFI-S KTUs there may 
be more KTU circuits installed (since there are 3 per 
KTU) then will actually be used. Any non-used circuits 
should be programmed as “not installed” when pro- 
gramming for CO/PBX line assignment. See Section 
300 “Programming” of this manual for instructions 
on programming CO/PBX line assignment. This will 
avoid confusion when attempts to access unconnected 
CO/PBX lines are made. The DSI-S or MFI-S in the 
first designated KTU position (DCI/MFI 1) serve CO/ 
PBX lines 1 through 3. A DCI-S or MFI-S in the 
second designated KTU position (DCI/MFI 2) serve 
CO/PBX lines 4 through 6. Refer to figure 230-2 for 
KTU positions in the Key Service Unit. See AHR-S 
KTU in Section 230 for information’on wiring change 
for providing Automatic Hold Release feature when 
AHR-S KTU is installed. 
2. KS1 -S KTU 
There are two designated KS1 KTU positions within 
the Key Service Unit. The KS1 -S in the first position 
(KS1 1) serves stations 1 through 8, while a KSI-S in 
the second position (KS1 2) serves stations 9 through 
16. Located on each KS!-S KTU are 8 fuses which are Smm by 20mm and are rated OSA 125V: one 
fuse for each keyset. The fuse provides protection on 
the data transmission pairs (DT and DR). When a fuse 
must be replaced refer to Section 140, “Fuse Replace- 
ment” of this manual. 
3. SWM-SKTU 
An SWM -S KTU must always be installed in SWM 1. 
An SWM-S KTU must be installed in SWM2 when 
either stations 9 
- 16 and/or CO/PBX lines 4 - 6 are 
to be connected.

230.3 Installing &mmon KTUs 
I. CPU-S STU 
Before programming the Network Plan Memory (NPM), 
ensure that the SW1 switch located on the CPU-S 
KTU is set to the ON position. This will provide 
battery back-up for the NPM, speed dial, and last 
number dialed memories when power is lost to the 
KSU. If there is a power failure and switch is left in 
the OFF position, the system will lose the contents of 
memory and return to the Resident System Program. 
For a description of the Resident System Program see 
Section 300 “Programming”. When the CPU-S KTU 
is removed for long-term storage, set the SW1 switch 
to the OFF position. This will prevent the battery from 
constantly discharging until it is no longer capable of 
holding a charge. The battery, when fully charged, 
will protect the memory for approximately 60 days. 
back-up to the Electra-616 system during a power I failure.

							On the CPU-S KTU is a momentary switch for system 
reset. Depressing the reset switch causes any program 
changes to enter the working program and interrupts 
all system operation in progress. 
2. CLK-S KTU 
SW1 
When DCI-S KTU(s) is installed ensure the switches 
SW1 and SW2 on the CLK-S KTU are set to appro- 
priate positions. Refer to Table 230-2 below. The 
switch settings are subject to the dialing specifications 
of the CO or PBX. The switches have been set by the 
manufacturer at 1Opps dial speed and at 39% make 
ratio.

230.4 installing Optional KTUs 
1. PBS-S KTU 
Install PBS-S KTU in ES-6-1 KSU when External 
Paging,Busy Lamp Field and/or Security options are 
required. Refer to Section 250.2 “EB-6-1 Installa- 
tion” for BLF connection. When installing External 
Paging and/or Security options, see Section 260, Instal- 
ling Options”. 
7 __ DPH-S KTU 
When a DPH-S KTU is installed in the ES-6-l KSU, 
two DP-6-1 can be used as Door Phone or Monitor 
Phone separately. 
When Door Phone 1 is required as a Door Phone, set 
the SW1 to the “D” position on the DPH-S KTU. 
(In the case of Door Phone 2, set the SW3 to the 
“D” position.) 
When Door Phone 1 is required as a Monitor Phone, 
set the SW1 to the “M” position on the DPH-S KTU. 
(In the case of Door Phone 2, set the SW3 to the “M” 
position.) and remove the straps Sl and S2 on the 
DPH-S KTU. (In the case of Door Phone 2, remove 
the straps S3 and S4). Then the voice from Key Set 
will be cut off when Door Phone is accessed, and the 
voice from DP-6-l is more amplified compared with 
being used as Door Phone.

3. AHR-S KTU 
Located on each DCI-S and MFI-S KTUs are three 
straps (one for each line circuit) that should be 
removed when AHR-S KTU is installed for Auto- 
matic Hold Release option. When AHR-S KTU is not 
installed, the straps should be left connected to the 
solder terminals. Refer to Figure 230-3 for terminal 
designations. The AHR-S will release a CO/PBX line 
which is on hold when the outside party abandons the 
call. A timed disconnect signal of more than 150 milli- 
seconds must be provided from the CO or PBX to 
enable this option (the AIIR-S does not recognize a 
reversal of polarity). The AHR-S KTU serves up to 
6 CO/PBX lines and is installed in ES-6-l KSU. 
Remove the straps when AHR-S KTrJ is installed.

							230.5 Volume Controls All volumes are pre-adjusted by the manufacturer. 
Refer to Table 230-3. 
1. AlI tones from the built-ii speaker in a keyset are 
controlled at the keyset by adjusting the volume dial 
located at the front of the keyset. 
Table 230-3 CLK Volume Controls 
2. 
System wide CO/PBX ring (station id!e) and intercom 
all call and zone paging are controlled by adjusting 
volume controls on the CLK-S KTU. Tone level is 
increased by turning the volume control clockwise.

250.1 ET-6-l installation 
The ET-6-l is a fully-modular electronic key tele- 
phone set. Each keyset requires 2pair cabling to the Main 
Distribution Frame (MDF). The maximum cable length is 
700 ft. using standard 24 AWG cable and 1,150 ft. using 
standard 22 AWG cable. Refer to Section 140, “Cabling 
Requirements”, of this manual. For keyset connection, 
see Figures 250-I and 2.50-2 and Table 240-2.
