Replacement of Internal Supercapacitor
1.
The supercapacitor board associated with the CPE100 is EPSACC001. Use this
part number when ordering replacements. Do not attempt to use any other
replacement part for this procedure.
WARNING
•
Perform all electrical replacements in a suitably clean and dry environment.
Clean away all surface contaminants before opening the electrical circuit
enclosure.
•
Protect the exposed circuitry from electrostatic discharge, as this may
destroy or disable components. Wear a ground-strap while working on
exposed circuitry.
•
Dispose of electrical circuit waste in accordance with local laws and
regulations. Supercapacitors retain charge for a significant period. A risk of
electrical shock exists while the supercapacitors are charged up. A discharge
could cause either personal injury or damage to equipment.
•
Be sure that the unit under repair has been disconnected from its power
source for 5 minutes. Do not attempt to replace until the supercapacitors
have discharged completely.
2.
Power off the unit and wait for 5 minutes to allow the internal supercapacitors to
discharge completely.
3.
Clean the exterior surfaces of the unit before bringing it into a suitably clean lab
environment.
