Storing and transporting circuit cards

Compliance with electrical and safety standards

After using the footprint template to mark the floor for the anchor holes,
ensure it is installed between the floor and the levellers. The template adds to
insulating the switch from electrical current. Also, slip the insulating feet over
the anchoring rods. The feet are brown or yellow disks provided in the
anchoring kit (either NTRU0325 for zone 2 anchoring or NTRU0327 for zone
4 anchoring).
Care is required to store or transport circuit modules.
Store each circuit module in its own antistatic material and transportation
package to avoid physical or ESD damage or the accumulation of dust on
contacts. Be careful not to damage the module while packaging it.
Store packaged circuit modules in areas where the relative humidity is less
than 95% and the temperature is less than 70 degrees Celsius (158
Fahrenheit). This significantly reduces the chances of warping the circuit
board and corrosion of electrical contacts. The nominal storage humidity is
55% and the nominal storage temperature is 20 degrees Celsius (68
Fahrenheit).
Passport 15000 or 20000 switches comply with North American and
international regulatory safety requirements for the handling and the
installation of equipment. For a complete list of standards, see "Standards and
compliance considerations" (page 159).
