Always place the modules on a conductive surface (table with an ESD coating, conductive ESD
foam, ESD bag or container). 1
Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm
away from the screen. 1
1.2.4 Measurements and modifications to ESD modules
Do not take measurements on such modules unless
the measuring device is grounded (e.g. via PE conductors) or
you discharge the measuring head just before taking measurements with a potential-free mea-
suring device (e.g. by touching an unpainted metal part of the controller casing).
Always use an grounded soldering iron if you carry out any soldering work.
1.2.5 Shipping ESD modules
Always store modules and components in conductive packaging (e.g. metallized plastic bags
or metal sleeves) and ship them in conductive packaging.
If the packaging is not conductive, place the modules in a conductive envelope before pack-
aging. (Use ESD bags, domestic aluminum foil or paper, for example. NEVER use plastic bags
or film). 1
If the module has integral batteries, ensure that the conductive packaging does not touch or
short-circuit the battery terminals and, if necessary, first cover the terminals with insulating tape
or material.
