Esd Warning; Tools; Pcb Information - ABB PST30 Manual

1. ESD Warning

Please note!
The life span of electronics can be affected by damage caused by
electrostatic discharge. This can happen if a charged tool or person
touches a component. Therefore it is very important that all tools and
personnel are discharged by touching an earthed point before the printed
circuit board or any of the components are touched. It is equally important
to discharge the package with the new component before opening it.
A person walking on a carpet can be charged with up to fifteen
thousand volt (15000V). Compare this with the fact that some sensitive
components can be destroyed when discharged on a much lower level
(about 100V). We kindly ask you to pay notice to this, as this is a vital
point in order to ensure the life span of the product.
