Today’s sophisticated electronic equipment requires superior
suppression filter systems. By selecting Joslyn®TransEnd™
devices, you have taken a critical step toward decreasing down-
time and ensuring longer product life for your equipment.
TransEnd is designed to protect facilities and sensitive electri-
cal and electronic equipment against the harmful effects of light-
ning strikes and internally generated electrical transients. These
reliable surge protection devices fulfill the single-pulse surge
current capacity testing recommendations per NEMA LS-1, 1992,
sections 2.2.9 and 3.9.
The Joslyn TransEnd combines easy installation with many
special features to deliver more performance than any other
device in its class.
TransEnd is conveniently pre-wired with 24-inch, stranded
#10 AWG pigtail conductors. To ensure optimum product perfor-
mance, install your TransEnd system in a location that minimizes
wire lengths and wire bends. This positioning maximizes surge
suppression and filtering while providing added protection for the
connected loads.
Thank you for choosing the Joslyn TransEnd Surge
Suppression System. We look forward to fulfilling your facility-
wide surge suppression filter system needs.

The versatile TransEnd product family is designed for facility-
wide installation. TransEnd 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
TransEnd devices. Proper product selection and compliance 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 ques-
tions, we recommend they consult with a master electrician or
other qualified electrical professional.
When shortcuts are taken or installation procedures are not
followed, the TransEnd system may be damaged or may not pro-
vide adequate protection. Improper installation may also void the
warranty. It is extremely important to follow these installation
procedures carefully.
This manual is designed to step you through the easy installa-
tion procedures. However, should you have questions about
installing TransEnd, please call Joslyn Technical Support at
800.238.5000.
WARNING! The TransEnd’s Warranty is voided if the unit is dam-
aged as a result of improper installation or the installer’s failure
to verify the following conditions prior to installation.
➤Confirm that the voltage(s) and power configuration shown
on the TransEnd product label are consistent with the voltage and
service configuration at the TransEnd installation site. One of the
following voltage and service configurations is printed on the
label affixed to the TransEnd:

Pre-Installation Checklist

➤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 TransEnd
devices (see NEC article 250.) Lack of a proper bond will dam-
age the TransEnd and void the warranty.
➤Confirm that the environmental conditions are consistent
with these ranges:
Ambient Temperature: The TransEnd must be installed in
an area with a temperature between -40° and +140° F
(-40°and +60° C.)
Humidity: The TransEnd must be installed in an area with
relative humidity between 5% and 95%, noncondensing.
WARNING! Discontinue installation if (1) your conditions are
inconsistent with the guidelines above or (2) your conditions
cannot be verified. Call Joslyn Technical Support at 800.238.5000,
if you have any questions.
TransEnd is to be connected in parallel with the electrical
system and must be fed by an overcurrent protection device
(20A circuit breaker or fuse) in a power distribution panel.
Figures 1-4 show the relationship between the TransEnd
device and these four basic service configurations: WYE,
DELTA, High-Leg DELTA and SPLIT-PHASE.

WARNING! Be sure power is off before terminating the TransEnd leads.
Raceway: To route TransEnd conductors to the panel being protected,
choose from any of these materials: (1) non-metallic flexible conduit,
(2) metallic flexible conduit, (3) rigid conduit or (4) a nipple. The
TransEnd enclosure is provided standard with a 3/4-inch hub which will
accept rigid or IMC conduit. A plastic flexible conduit with fitting and
a 3-inch nipple are available as options.
Wire length: Use the supplied 24-inch, #10 AWG leads. Trim leads to
suit the application but do NOT splice to add length to the leads. Refer
to Figures 1 through 4 for the color code of the TransEnd leads.
Terminate the leads as shown. (Note: For optimum performance, keep
leads as short as possible and avoid sharp bends.)
Overcurrent protection: TransEnd leads must be protected with an over-
current protection device (circuit breaker or fuse) rated at 20 amps. Use
a 3-pole breaker for 3-phase units or a 2-pole breaker for single-phase
units.
Dry Contacts: For TransEnd units with optional Form “C” dry
contacts, use butt splices within the panelboard to connect the Form “C”
leads to the user’s monitoring circuits. Alternatively, install a junction
box between the TransEnd and the panelboard to connect Form “C”
leads to user’s monitoring circuits. (See Fig. 6 under “Options,” page
8). Consult applicable local codes to ensure proper installation.
➤Measure the line to line voltage at the panel to be protected and be
sure it is within ±10% of rated line to line voltage of the TransEnd. Use
the following table to determine the range of acceptable voltage for
each model of TransEnd.
Acceptable Voltage Ranges for All TransEnd Models
TRANSEND NOMINAL L-L -10% to +10%
MODEL NO VOLTAGE L-L VOLTAGE
XNxxx-120/240-2G 240 216 to 264
XNxxx-120/208-3GY 208 188 to 228
XNxxx-220/380-3GY 380 342 to 418
XNxxx-277/480-3GY 480 432 to 528
XNxxx-120/240-3GHD 240 216 to 264
XNxxx-240-3DG 240 216 to 264
XNxxx-380-3DG 380 342 to 418
XNxxx-480-3DG 480 432 to 528
WARNING! Do not apply power if the measured voltage is not within
the range specified for the TransEnd model being installed. Do not hi-
pot the electrical system that the TransEnd is connected to without
disconnecting all TransEnd conductors including phases, neutral and
ground.

➤Apply power to unit by closing the circuit breaker.
➤Check TransEnd lights. Protection is active when all
lights are illuminated.
Call Joslyn Technical Support if you experience either
of these conditions:
• Circuit breaker trips and cannot be reset
• One or more lights on TransEnd are not illuminated
Our staff is available to support you around the clock.
Monday through Friday, 8:00 a.m. to 5:00 p.m. (EST),
call 800.238.5000 or 804.236.3300.
The TransEnd is available with these options:
• Form “C” dry contacts for remote monitoring. Upon failure
of any phase, the relay’s N.O. and N.C. contacts will
change state. The contacts are rated at 110VDC/125VAC with
maximum switching power of 30W DC/62.5VA AC.
• 18 inches of 3/4-inch nonmetallic flexible conduit and
a fitting that connects to the provided 3/4-inch hub.
• 3/4-inch x 3-inch nipple that connects to the provided
3/4-inch hub.
The only operational verification necessary on the TransEnd is to
observe that the lights are illuminated. There is no maintenance to
be performed on the TransEnd nor does the TransEnd contain any
user-serviceable parts.
