KSU CABLING
Two (2) Amphenol-type connectors are provided on
the left side of the KSU (Refer to Figure 400.3).
On the right edge of the front surface are the RJI 1 C
connectors which are for CO lines. On the left side
surface of the 616 FLEX KSU are two connectors
marked J-l and J-2. The J-l connector is located just
below the J-2 connector. J-l and J-2 require 90
degree male ended plug cables for proper attach-
ment.
When connecting cable tails to the KSU, make sure
the designation on the AMP hood matches the des-
ignation at the connector’s input on the KSU.
After plugging in the required cables, a “horse shoe”
fastener should be placed around the mated AMP
connectors to secure the cable to the KSU connec-
tor.
Verify that the wires are properly cross-connected.
Observe the telephone standard wiring color codes
whenever possible. Some points to be aware of
while running the key telephone cabling are:
Cabling should be routed to avoid fluorescent light
fixtures, electric motors and generators, welding
equipment and radio transmitters. Additionally, care
should be taken to avoid hot locations such as steam
pipes and furnaces, and areas where wiring is sub-
ject to abrasion.
It is NOT recommended that power be ap-
plied to the system during the cable termi-
nation process.
500.6 LIGHTNING PROTECTION
The 616 FLEX should have central off ice lines pro-
tected with proper lightning surge arrestors. The
central office lines are exposed to damaging surges
induced by direct or non-direct lightning strikes.
The protection should contain a complement of 3-
element gas discharge tubes which ground high
potential surges, and associated circuits to absorb
and filter lower-level surge potentials. Care should
be taken to ensure that not more than one set of
protectors be installed on central office lines at in-
stallation premises. Improper installation of line pro-
tection can present a serious safety hazard.
500.7 KEY TELEPHONE INSTALLATION
A maximum of sixteen (16) key telephones may be
installed with the 616 FLEX Key System. Each key
telephone requires 2 pair (4 wires) for proper wiring.
It is recommended that 3 pair twisted pair cable be
used to connect the telephones to the system on a
“home run” basis. The telephone end of the cable
should be terminated on a modular jack. At the MDF
end of the home run, the cable should be terminated
on a separate station connecting block (66Mi -50) for
cross connection to the “J” cables. This method of
cabling will allow for easy isolation of station equin-
ment during trouble shooting procedures.
500.8 WALL MOUNT KIT INSTALLATION
All connections to the Key Telephones are fully
modular. To wall mount the Key Telephone, it is
necessary to have one Wall Mount Kit and one (1)
630-A type modular wall mount jack assembly
equipped with two mounting lugs.

Remove the mounting cord from the telephone.
This cord will no longer be needed.
Substitute the short modular cord on the wall
mount baseplate for the mounting cord re-
moved in A above.
Rotate the plastic number retainer upwards to
expose the screw underneath. Remove the
screw and slide the cover plate under the num-
ber retainer towards the hookswitch.
Replace the cover plate with the handset re-
tainer tab that is mounted in the wall mount
base plate, and secure with the screw from C
above.
Rotate the plastic number retainer downwards
and snap into place.
Align the mounting tab on the outer edges of
the wall mount base with the holes on the key
telephone base. Snap shut and fasten with the
screw.
The telephone can now be mounted to the wall
by mating the two keyhole slots on the base-
plate with the lugs on the modular cover assem-
bly. Check to make sure that the modular
connector on the baseplate has a firm connec-
tion with the connection on the wall jack. (Figure

500.9 PHONE BOX INSTALLATION
The 616 FLEX Phone Box can make calls to preas-
signed stations as well as receive intercom calls. The
unit should be located in weather protected areas
where paging or monitoring is required.
