Safety
Electrical Shock
This device may generate voltages that may be harmful to the body or cause
death. Several protections are included in the device, reducing the risk of
electroshock to a minimum, but basic safety precautions must be taken.
Ensure that nobody is inside the area of influence of the injection of
current, and that nobody is handling the wires before starting the
current injection sequence.
In the case of initiating the sequence (pressing “START” button in the PDA
device), sequence can be aborted at any moment:
- by pressing the “STOP” button
- by moving the safety key to the “Disabled” position
- by breaking the Bluetooth link (either removing the PDA battery or
any other possible way)
- by switching off the circuit breaker
Safety key and circuit breaker are not hardware/software dependant, as they
act directly on the mains supply (breaker) or the current output (safety key),
so even in case of an highly improbable software/hardware failure, those
ones will avoid the current injection.
If sequence is not aborted, MPC device will perform a first 25V trigger. If
resistance found is bigger than 120 Ohms, a message will appear on the
PDA screen warning the user, and asking whether to continue or not.
Taking into account that body resistance in normal conditions is about
1Kohm, this warning is a basic protection feature.
In case of continuing the sequence, new MPC will only apply current during
20ms. As per IEC 60479-1, this voltage shouldn’t cause ventricular
fibrillation, even under water wet conditions, while touching the conductive
parts with the palms of the hands, but medical assistance may be required.
Remember that this device may generate lethal voltages.
Operator safety protections are required.
In case of risk or device malfunction, do not doubt to abort the
triggering sequence.
