CAUTION:
An electrostatic discharge wrist strap with a minimum
resistance of 250K Ohms should be worn when handling
Series 5 circuit packs to prevent possible damage to the
circuit packs. Before using the wrist strap, check it for opens,
shorts, and minimum resistance value. If the strap does not
pass these checks it should not be used. To avoid possible
personal injury while using the wrist strap, do not connect it
