Original Service Manual 3 Rev 2.1, January 2021

❖Electrostatic discharge (ESD)

CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components.

Handle static-sensitive components using safe practices.

CAUTION Assume that all electrical and electronic components of the appliance are

static-sensitive.

Electrostatic discharge is a sudden current flowing from a charged object to another objector to ground.

Electrostatic charges can accumulate on common items such as foam drinking cups, cellophane tape,

synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to

name only a few.

Electronic components and assemblies, if not correctly protected against ESD, can be permanently

damaged or destroyed when near or in contact with electrostatic charged objects. When you handle

components or assemblies that are not in protective bags and you are not sure whether they are static-

sensitive, assume that they are static-sensitive and handle them accordingly.

• Always use techniques to protect personnel and equipment from electrostatic discharge.

➢ESD Wrist or Heal strap (recommended for appliance and personal safety)

• Remove static-sensitive components and assemblies from their static-shielding bags only when you

are stationary and prepared to immediately install the component.

• Remove / install static-sensitive components andassemblies only with appliance power disconnected.

• Insert and seal static-sensitive components and assemblies into their original static-shielding bags.

• Always test your ESD strap before beginning any disassembly or assembly procedures.
