SYSTEM INSTALLATION INSTRUCTIONS
500.1 SITE PLANNING
The STARPLUS 616 FLEX Electronic Key Tele-
phone System, like most electronic office equip-
ment, should not be subjected to harsh
environmental conditions. To assure easy servicing
and reliable operation, several factors must be con-
sidered when planning the system installation. AI-
ways consider the following BEFORE installing the
KSU and wiring:
A.
B.
c.
D.
E.
F.
G.
H.
I.
The KSU is designed for wall-mounting only.
The internal power supply operates with 117
VAC, 60 Hz, single-phase electricity. A 3-wire
(parallel blade with ground) receptacle must be
provided on a dedicated, separately fused 15
AMP circuit.
Location(s) of telephone conduits or cable runs.
The KSU should be within 25 feet of the tele-
phone company (TELCO) RJllC. The KSU
should be centrally located and assurances
should be made to stay within prescribed cable
lengths.

A well ventilated area having a recommended
temperature range of 60 to 80 degrees Fahren-
heit, and a humidity range of 5 to 95% (non
condensing).
Accessibility of KSU for servicing and lighting.
Protection from flooding, flammable materials,
excessive dust and vibration.
Proximity of radio transmitting equipment, arc-
welding devices, copying machines and other
electrical equipment that are capable of gener-
ating electrical interferences.
Access to a good earth ground such as a me-
tallic COLD water pipe. Inspect the pipe for
non-metallic joints.
500.2
UNPACKING THE 616 FLEX KSU
Remove the KSU from the shipping carton and place
it on a level working surface, face up. Inspect the
KSU for physical damage. The KSU has no service-
able parts.
500.3
KSU GROUNDING
To ensure that the system will operate properly, a
good earth ground is recommended. The Telco
protector ground terminal or a metallic COLD water
pipe will usually provide a reliable ground path. If
cold water pipe is used, carefully check that the, pipe
does not contain insulated joints that could isolate
the ground. In the absence of the cold water pipe, a
ground rod or other source may be used. A No. 8
AWG copper wire should be used between the
ground source and the KSU.
THE GROUND WIRE SHOULD BE KEPT AS
SHORT AS POSSlBLE AND CAN BE CON-
NECTED TO THE GROUND LUG LOCATED ON
THE SIDE OF THE KSU. (Figure 400.4)
500.4
KSU INSTALLATION
The KSU is designed for wall mounting only. The
KSU should NOT be mounted directly on a masonry
surface.
If the KSU is to be mounted on a masonry surface,
a wooden backboard of sufficient size should be
attached to the wall and the KSU mounted on the
backboard.
A.
B.
C.
D.
Mount the KSU on the backboard using four
fasteners. (The fasteners should be selected
carefully so as to be capable of supporting the
KSU.) (Refer to Figure 500.1 for KSU dimen-
sions.)
Install the ground using an insulated 8 AWG
copper wire. Attach one end to the grounding
lug on the side of the KSU cabinet and fasten
the other end to a good earth ground (Refer to
Figure 400.2 KSU layout).
The KSU power supply is located within the
KSU. Because the KSU is a sealed unit, all
electrical connections are provided externally.
The power cord exits the KSU on the right side.
Also on the right side is a fuse holder that
contains a 0.7 Amp. slow- blow fuse. Power for
the system is distributed internally.
The power cord should not be used with a
3-wire-2-wire plug adapter. A power line surge
protector should be used to protect the power
supply from electrical surges. The surge protec-
tor should be installed in accordance with the
manufacturer’s instructions and applicable lo-
cal electrical codes.
