TPS4-01 Surge Protection Device |
Installation Guide / User Manual
•
This manual shall be read in entirety prior to installing
• Only qualified licensed electricians should install or service SPDs
• Hazardous voltages exist within SPDs
• SPDs should never be installed or serviced when energized
• Use appropriate safety precautions including Personal Protection Equipment
• Failure to follow these instructions can result in equipment damage, serious injury and/or death.
Bonding and Grounding Hazard
Verify that the neutral conductor in the service entrance equipment is bonded to ground in accordance with the
National Electrical Code (NEC®) and all applicable codes.
Verify that the neutral terminal (XO) on the secondary side of distribution transformers are grounded to the system
ground in accordance with the NEC® and all applicable codes.
During installation into an electrical system the SPD must not be energized until the electrical system is completely
installed, inspected and tested. All conductors must be connected and functional including the neutral (if required).
The voltage rating of the SPD and system must be verified before energizing the SPD.
Failure to follow these guidelines can lead to abnormally high voltages at the SPD. This may cause the SPD to fail.
The warranty is voided if the SPD is incorrectly installed and/or if the neutral conductor in the service entrance
equipment or downstream of separately derived systems is not bonded to ground in accordance with the NEC®.
Do Not Hi-Pot Test SPDs
The TPS4 unit needs to be fully disconnected during Hi-Pot testing. Failure to disconnect SPD and associated
components during elevated voltage testing will damage the SPD and will void the warranty.
Siemens TPS4 SPDs have the following Type designations:

TPS4 01 & L1
Type 1 & 2 Component Assembly
For further information, please review latest editions of
NEC® Art. 285, UL 1449, contact your local Siemens sales
office or contact Siemens TPS Tech Support at 800-333-7421.
Equipment Performance
As SPDs sense overvoltage, they create a momentary
internal short circuit, thereby redirecting harmful surge
energy to earth ground. SPDs are capable of repeating this
function repeatedly. For optimum protection, staged surge
suppression should be implemented at the service entrance
and all other distribution or panelboard locations feeding
sensitive equipment.
Voltage Rating
Prior to installing the TPS4 SPD, verify that the unit has
the correct voltage rating for the equipment installed
by checking the nameplates of both the equipment
and TPS4 module. The service type should match the
intended power source. See Table 2 on the following
pages for voltage applications.
