Introduction
An on-board fuse protects the 24V DC input circuitry from damage through
higher voltages than those expected or AC voltages being inadvertently
applied to the system. This fuse, should it be assumed defect (the Power In
LED on the housing will not be illuminated), may be accessed by removing
the cover of the SMART-BASE and accessing the holder on the left-hand
side as shown in the illustration below.
In the event of a blown fuse, replace it with the same size and type as the one
installed.
