Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different
electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when
electronic components are improperly handled, and it can damage equipment and impair electrical
circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and
dry atmosphere.
Use an antistatic strap during removing and replacing DAS3 Series units.

Use an antistatic strap during removing and replacing DAS3 Series units.
Always use an ESD ankle or wrist strap and ensure that it makes good skin contact.
To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable
attached. If cables are connected at one end only, do not touch the exposed pins at the unconnected
end of the cable.

This equipment is intended for use in residential and commercial environments only.
Periodically check the resistance value of the antistatic strap, which should be between 1 and 10
megohms (Mohms).

General Maintenance Guidelines
The following maintenance guidelines apply to DAS3 Series system units:
Keep the DAS3 Series box area clear and dust-free during and after installation.
If you remove the chassis cover for any reason, store it in a safe place.
Do not perform any action that creates a hazard to people or makes equipment unsafe.
Keep walk areas clear to prevent falls or damage to equipment.
