Today’s sophisticated electronic equipment requires superior
suppression filter systems. By selecting Superior Electric’s
devices, you have taken a critical step toward decreasing down-
time and ensuring longer product life for your equipment.
The CS1 series STABILINE ®Surge Suppression System is
designed to be connected to your electrical distribution system to
protect connected sensitive electrical and electronic equipment
against the harmful effects of lightning strikes, internally generat-
ed transients and high frequency noise. The reliable CS1 fulfills
the single-pulse surge current capacity testing recommendations
per NEMA LS1-1992, paragraphs 2.2.9 and 3.9.
It combines easy and flexible installation with many special
features to deliver more performance than other devices in its
class.
The CS1 offers a full range of monitoring options from the
most basic phase indicator lights and audible alarms to the most
sophisticated power quality monitoring features offered in any
surge suppression product. These features include
the following:
• Display of true RMS phase voltages
• Display of neutral-to-ground voltage and current
• Counting of swells, surges, sags and outages
• Display of percent available protection remaining
The CS1 series incorporates redundant MOV fusing that
prevents individual component failure from rendering the protec-
tion mode useless. Instead, the failed component safely removes
itself from the circuit and all remaining protection is allowed to
continue operating as designed. Special circuitry allows the
percent remaining protection to be measured and automatically
alarmed if capacity drops below 50 percent.
The standard CS1 is available in a fiberglass-reinforced
polyester NEMA 4X enclosure. It is available with or without an
integral disconnect. Units equipped with disconnects are available
only with a metallic NEMA 4/12 enclosure.
Thank you for choosing a CS1 series STABILINE Surge
Suppression System. We look forward to fulfilling your facility-
wide surge suppression filter system needs.

®products are warranted for a
period of seven years from date of purchase.
The CS1 series is designed to provide surge suppression to
all connected loads within a distribution system. The CS1 uses
proven Metal Oxide Varistors (MOVs) and an efficient capacitive
filter system to reduce or eliminate transients, impulses, and high-
frequency noise within a building’s electrical system.
This manual provides guidelines for the proper installation of
the CS1 series of devices. Proper product selection and compli-
ance with these guidelines will help your new suppression system
provide years of reliable service. If installers are unsure about
the facility’s electrical configuration or have other installation-
related questions, it is recommended they consult with a master
electrician or other qualified electrical professional.
When shortcuts are taken or installation procedures are not
followed, the CS1 system may be damaged or may not provide
adequate protection. Improper installation may also void the war-
ranty. It is extremely important to follow these installation proce-
dures carefully.
This manual is designed to assist you with the installation of
the CS1 product and connecting it to your electrical system.
However, should you have questions about installing the
WARNING! The TVSS series warranty is voided if the unit is damaged
as a result of improper installation or the installer’s failure to verify
the following conditions prior to installation.

Before beginning
➤ Confirm that the voltage(s) and service configuration shown
on the CS1 product label are consistent with the voltage and
service configuration of the facility to which it is being attached.
A model number is printed on the label affixed to the inside of
the CS1 enclosure. Each model number corresponds to the volt-
age and service configurations printed in the table below:
(B phase must be 208V)
Note: Indicate TVSS surge current rating by substituting 60, 80, 100, 125,150,
200, 250, or 300 for “xx” in the above model numbers.
➤Check to ensure that a proper Xo bond is installed between
the neutral and ground terminals at the transformer upstream from
all 3ø WYE, 3ø high-leg DELTA, or 1ø SPLIT-PHASE TVSS
devices (see NEC Article 250.) Lack of a proper bond will
damage the CS1 and void the warranty.
➤Confirm that the environmental conditions are consistent with
the following ranges:
• Ambient Temperatures: The CS1 must be
installed in an area with a temperature between -40°
and +140°F.
• Humidity: The CS1 must be installed in an area
with relative humidity between 5% and 95% non-
condensing.
• Altitude: The CS1 must be installed in a
location whose altitude is below 13,000 feet.
WARNING! Discontinue installation if (1) your conditions are inconsis-
tent with the checklist above or (2) your conditions cannot be veri-
fied. Call Technical Support at 860.507.2025, ext. 70782 if you have
any questions.

The CS1 is to be connected in parallel with the electrical
system. It may be connected via a circuit breaker, molded case
switch, fused switch, or connected directly to the bus of the pan-
elboard or switchboard it is protecting. If direct bus connection is
used, Superior Electric recommends that the CS1 be equipped
with the optional integral disconnect switch.
• Do not connect the CS1 to the line side of the
main service breaker or disconnecting means.
• Do not install the CS1 where the available short
circuit current to the unit is less than 1500
RMS symmetrical amperes.

WARNING: The performance of the CS1 will be severely limited
if the conductors are too long, are of too small a wire gauge, have
too many bends or have sharp bends.
Conductor Routing: The above factors should be addressed
during the design of an installation to ensure that there is a
suitable place for the CS1 reserved next to its point of connec-
tion to the electrical system. The selected mounting
location should ensure short conductor runs providing a direct
route with a minimum of bends. If bends are required they
should be sweeping bends. Do not make sharp 90˚bends for
“aesthetic” purposes.

Conductor Sizing: Superior Electric recommends installing the
following conductor sizes for phase, ground, and neutral connec-
tions. Where space and bending radii permit use a larger conduc-
tor size:
Note: The above conductor sizing recommendations ensure that the effective
clamping voltage of the TVSS at the point of connection is kept to a minimum in
order to maximize protection. Increasing conductor size to compensate for dis-
tances over 10 feet has a negligible effect on minimizing clamping voltage.
Additionally, conventional voltage drop calculations appropriate for 60 Hz do not
apply to transients.
Overcurrent Protection: The design may require, or the installer
may choose, to connect the CS1 to a circuit breaker, molded
case switch or fused disconnect.
Superior Electric recommends feeding all CS1 models not
equipped with an integral disconnect with a circuit breaker, mold-
ed case switch or fused switch.
If a breaker or molded case switch is used for connecting
the phase conductors, Superior Electric recommends a 100 amp
rating.
WARNING: If the available short circuit current at the CS1 is less
than 1500 RMS symmetrical amperes, do not install the CS1.
Examples of systems with available short circuit currents less
than 1500 amperes include the outputs of small UPS systems and
small AC inverters.
