Is it safe to change components of my system (sensors, motors) without turning off the power?
We advise against this procedure.
This can bring multiple other issues including but not limited to:
Charge peaks in the capacitors.
Increase in the risk of damage due to ESD.
Increase in the risk of connector malfunction.
Terminal deterioration due to sparks.
Increase in the risk of single pole connection.
This advice applies even in cases when this sounds safe. Such cases include:
STO activated.
Plugging/unplugging connectors (not using stray wires).
