KEY TELEPHONE SYSTEM
500.22 POWER-UP AND INSTALLATION
CHECKUST
Prior to actual power-up and initialization, the key
system should be checked over to avoid start up
delays or improper loading. A step-by-step checklist
is provided for this purpose:

Ensure that the KSU is properly grounded ac-
cording to the instructions in Sec. 500.3.
Inspect the MDF for shorted wiring or improper
polarity that would affect the Key telephones.
Make sure that plug-ended MDF cables to the
KSU are secure and are plugged into the cor-
rect position.
Make sure the Program Module is seated firmly
in its socket.
Plug the AC power cord into the dedicated 117
VAC outlet.
wall. Replace the cover removed above. Refer to
Figure 500.9 for size and dimensions.
D. Wiring
The SLA is designed with screw terminals to make
connection to the KSU via the MDF simple. This can
be done riaht at the MDF usina cross connect wire
to make connection between the punch down blocks
and the SLA. Before attempting to make connec-
tions remove the plastic safety strip from the termi-
nals. Refer to Figure 500.12 for wiring connections.

The installer should exercise caution when
connecting a SLA while system power is
ON. Also the proper polarity of the wired
connections must be maintained for proper
operation.
KSU Station (input)
Using Cross connect wire connect from the station
block (Jl or J2) to the “INPUT 1” or “INPUT 2”.
Connect all four (4) leads from a station circuit (VT,
VR, DT, and DR leads) to the corresponding input
screw terminal. When connecting the leads into the
SLA, strip i/4 of an inch of wire before inserting into
the screw terminal.
The SLA communicates to the KSU on the INPUT 1
port only, therefore when installing only one port the
SLA Input 1 connector must be used. When install-
ing both SLA ports KSU “sister” station ports must
be used i.e. KSU station port 03 and 04 or 05 and 06
or 07 and 08 etc...). It is not recommended that KSU
station port 01 be used for SLA applications, as this
port serves as the system programming port.
Single Line Telephone wiring (output)
From the SLA adapter cross connect the SL leads
(Tip and Ring) to the station block where the home
run cable of the SLT device is terminated.
E. SLA Programming
It is necessary to program the system for proper SLA
operation. Refer to Station Configuration, Station ID,
Sec. 610.8 for programming procedures.
