Important Note: The protection effectiveness of the Low
Voltage/High Energy Surge Suppressor, or any other surge suppressor,
depends on many factors, including details of installation,
vulnerability levels of protected equipment and magnitudes of actual
transients, in addition to the suppressor characteristics. Therefore,
LDS can make no guarantee of protection effectiveness nor assume any
responsibility for loss or damage to protected equipment.
