The DTK-DF120S1 is a series connected Surge Protective Device with a replaceable
surge module.The LED indicators on the top face of the DTK-DF120M provide power,
ground and surge module health status. When the DTK-DF120M surge module has
gone end of life, the large “REPLACE” RED LED will illuminate and the “GOOD” LED
will turn off. Also, the audible alarm will sound to provide an extra alert as to the surge
module’s health. To silence the alarm, remove the dead module and replace it with a
new, unused module. If a new module is not available, the alarm can be silenced by
moving the toggle switch into the A, or BYPASS position. When a new DTK-DF120M
surge module is available, this toggle switch must be moved to the B, or the NORMAL
position before installing the new module. This action will also require the cover to be
removed to gain access to this switch. The red polarizing keys insure that the correct
voltage module will mate with its corresponding base.
CAUTION: By removing the cover, you will be exposed to live metal parts and there is
a risk of electrocution.
WARNING: Removing the cover should only be performed by a licensed electrician.
WARNING: When the DTK-120M module has gone end of life, or is missing, the
base is susceptible to damage from surge energy. Make sure you always have a
spare module available. No substitutions shall be permitted.
