removing the separate fuse or by means of a mains
isolator, and check that it is no longer live.

power circuits.

severe injuries. Some components on PCBs
remain live even after the power supply has
been switched off.
Prior to removing covers from the appliances,
wait at least 4 minutes until the voltage has
completely dropped out.
