To replace the fuse(s):
DISCONNECT THE POWER SUPPLY BEFORE PROCEEDING!
• First, using a flat-bladed screwdriver, use the slot to pry open and swing back the
hinged flap.
• Next, extract the press-fit fuse holder:
o
Using the screwdriver, disengage the fuse holder outward from the DC power module.
o
Using your fingers, pull the holder straight out of the module.
• Then, remove and replace the T8A (8 Amp) fuses as needed.
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH THE
