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-DF240M 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.
The DTK-DF240S1 is a series connected Surge Protective Device with a replaceable surge
module.The LED indicators on the top face of the DTK-DF240M provide power, ground and
surge module health status. When the DTK-DF240M surge module has gone end of life, the
large “REPLACE” RED LED will illuminate and the “GOOD” LED will turn off. Also, the audi-
ble 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 pressing the tactile switch, located at the
bottom of the enclosure, into BYPASS mode for 24 hours. The red polarizing keys ensure
that the correct voltage module will mate with its corresponding base.
