Changing Fuses
• Turn off CPC 100, unplug the power cord and/or press the Emergency Stop
button.
• We recommend to wait for about 30 seconds. This time is necessary for the
internal electrolytic capacitors to fully discharge.
• Ground the test object, and disconnect it from CPC 100. By disconnecting it
you prevent a possibly faulty test object feeding power back into CPC 100.
• Locate the blown fuse on the front panel of CPC 100, and replace it:
– 6.3A T (6.3 Amps slow-acting wire fuse 5x20mm) for AC OUTPUT in 6A
operation mode

or for DC OUTPUT.
– 3.15A T (3.15 Amps slow-acting wire fuse 5x20mm) for AC OUTPUT in
130V operation mode.
– 10A FF (10 Amps very-quick-acting wire fuse 5x20mm) for measuring
inputs.

to ”Functional Components of CPC 100” on page 2-2.
Note: Replace with identical fuse type only.
