Vibration and Shock

The NA Unit is tested for conformity with the sine wave vibration test method (IEC 60068-2-6) and the
shock test method (IEC 60068-2-27) of the Environmental Testing for Electrotechnical Products. It is
designed so that malfunctioning will not occur within the specifications for vibration and shock. If, how-
ever, the NA Unit is to be used in a location in which it will be directly subjected to regular vibration or
shock, then implement the following countermeasures:
• Separate the control panel from the source of the vibration or shock.
Or, secure the NA Unit and the panel with rubber padding.
• Make the building or the floor vibration resistant.
• To prevent shock when other devices in the panel such as electromagnetic contactors operate,
secure either the source of the shock or the NA Unit with rubber padding.

Atmosphere

Using the NA Unit in any of the following locations can cause defective contact with connectors and cor-
rosion of components. Implement countermeasures such as purging the air as required.
• In locations exposed to dust, dirt, salt, metal powder, soot, or organic solvents, use a panel with an
airtight structure. Be careful of temperature increases inside the panel.
• In locations exposed to corrosive gas, purge the air inside the panel to clear the gas and then pres-
surize the inside of the panel to prevent gas from entering from outside.
• In locations where flammable gas is present, either use an explosion-protected construction or do not
use the NA Unit.
