Furthermore the entire medical system has to be connected via an additional potential-equalization-cable to the potential-equalization-bar in

the medically used room / facility. During installation, connecting or disconnecting, the terminal must be disconnected from the power supply! Protection against electric shock has to be provided in the finished product/device.
