-
Incorrect wiring may lead to loss of safety function. Wire conductors correctly
and verify the operation of the DST1 before commissioning the system in which
DST1 is incorporated.
-
After wiring is completed, be sure to remove label for wire clipping prevention on
the DST1 to enable heat to escape for proper cooling
