In this manner you avoid static discharge.Avoid direct contactYou should only touch ESD components if this is unavoidable (for example,during maintenance work). Hold the modules so that you touch neither pins norprinted conductors. In this manner, the discharge energy cannot reach or damagesensitive devices.If you have to carry out measurements on a module, discharge yourself beforecarrying out any actions. Do so by touching grounded metallic parts. Only usegrounded measuring instruments.
