► SAFETY of up to 35,000 volts if you walk across a non-conductive carpet, ► of up to 12,000 volts if you walk across a non-conductive PVC floor, ► Term of up to 1,800 volts if you are sitting on an upholstered chair. The electrostatic voltage on your body is transferred to the electronic Electrostatic components and ESDs you touch which may be damaged as a result. - Page 4 1.1.3 ESD instructions All electronic modules and electronic assemblies feature electrostatic sensitive devices. The following measures must be taken in order to protect these electrostatic sensitive devices: Ensure that the assemblies and modules are appropriately identified. Before you touch and measure the ESDs, put on an electrostatic protection system (wrist band with earthing module).
