INSTALLATION INSTRUCTIONS FOR:
NOTE
SPD’s must be connected to the electrical service with appropriate ampacity Class T Fuse, rated 300V. Equipment Safety
Grounds MUST be run separately - not through the traces of the Surge Protection Device.
WARNING
ANY ALTERATIONS, TAMPERING, MISUSE OR UNAUTHORIZED REPAIRS OF THIS SPD WILL VOID ITS
ORIGINAL FACTORY WARRANTY.
INSTALLATION
1. This document provides detailed information on how to install and operate the TST Series of Surge Protecion Devices (SPDs).
2. SPD’s should be installed per the information and illustrations provided herein.
3. SPD’s are installed/connected in either series or parallel with the line and the equipment to be protected.
4. Identified or indicated Leads/Wires must be connected exactly with respect to the power feeding/supplying the SPD and
equipment. Failure to do so may result in damage to the SPD, the equipment/system or pose a danger to personnel.
5. Incorrect installation may significantly impair the performance of the SPD. It is particularly important that all installation
procedures and guidelines be followed exactly.
6. Prior to installation, verify service voltages (AC or DC) with a volt meter to ensure that the correct model has been
selected for the supply voltage.
7. DO NOT INSTALL THE SPD IF MEASURED VOLTAGE EXCEEDS UNIT RATINGS.
8. The SPD MUST BE mounted in an enclosure to assure personnel safety from exposed terminals.
9.
REMOVE POWER FROM ELECTRICAL SYSTEM PRIOR TO INSTALLATION.
10. The SPD should be positioned as the last device in the circuit prior to protected equipment.
11. The SPD Line/Load designations are for orientation purposes only and do not effect the install.
12. Mechanically mount the SPD utilizing the mounting tabs or attach the din rail.
13. For Series (AC) Applications
A) Connect “LINE” Side:
* System Ground to the terminal labeled “G”
* Neutral or Line 2 wire to the terminal labeled “L2”
* HOT wire to the terminal labeled “L1”
B) Connect “LOAD” Side:
* System Ground to the terminal labeled “G” (connect safety ground directly to enclosure ground)
* Neutral or Line 2 wire to the terminal labeled “L2”
* HOT wire to the terminal labeled “L1”
14. For parallel (AC) Applications, keeping lead as short as possible
* System Ground to the terminal labeled “G”
* Neutral or Line 2 wire to the terminal labeled “L2”
* HOT wire to the terminal labeled “L1”
NOTE:
In parallel applications, SPD’s are not current limited as they are in series applications. For parallel applications,
unused output terminals are left empty, no plugs are provided.
15. ENSURE THAT ALL CONNECTIONS ARE CORRECT BEFORE ENERGIZING.
16. Apply power (energize). LED indicator should illuminate. If light fails to illuminate, contact supplier. If LED is out, unit
requires service.
17. Keep this MANUAL in a safe dry place for future reference.
