Important notes concerning electrostatic discharges (ESD)
Electrostatic discharges can cause damage to PCBs and other compo-
nents. You can obtain a certain protection by wearing anti-static gloves or
wrist-wraps that you can connect for grounding on the mass of any un-
painted metal piece of the machine head or on the switch cabinet.
Handle the PCBs with utmost caution. They are very sensitive towards
electrostatic discharges. Hold the PCBs only at their edges.
Put the PCBs after unwrapping or after dismounting with their components
upside onto a grounded statically discharged surface.
We recommend to use a conductive foam underlay but not as the protec-
tive cover of the PCB.
Pay attention not to pull the PCBs over any surface.
