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 NCT480 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 NCT480 system units:
Keep the NCT480 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.
