TRANSEND
INSTALLATION, OPERATION AND MAINTENANCE MANUAL ISSUED 6.01
®
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.
