Measuring and changing ESD modules
Measure the ESD component under the following conditions only:
•
The measuring device is grounded with a protective conductor, for example.
•
The probe on the potential-free measuring device has been discharged, e.g. by touching
the bare metal of a part of the switch cabinet.
•
Your body is discharged. To do so, touch a grounded metallic component.
Solder only with grounded soldering irons.
Shipping modules susceptible to electrostatic discharge
Always store or ship ESD components in conductive packaging, e.g. metallized plastic boxes
or metal cans. Leave the components and parts in their packaging until installation.
If the packaging is not conductive, wrap the ESD component in a conductive material, e.g.
rubber foam, ESD bag, household aluminum foil, or paper, before packing. Do not wrap the
ESD component in plastic bags or plastic film.
In ESD components containing installed batteries, make sure that the conductive packaging
does not touch the battery connectors or short circuit. Insulate the connectors with suitable
material.
