What’s an overvoltage suppressor? Is this a built in standard and how does it look like?

An overvoltage suppressor (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge suppressor attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.

These surge suppressors are built in to the latest Pacemaker models (from 2009).

Check, if one or more plugs of the surge suppressors are red/defect. Replace the red plugs.
