Power supplies and drives have capacitors that store electricity even when power supply has been disconnected from the power network. This poses electric shock hazard when touching a device that has been just unplugged from the power line.
Safely discharging Argon drive
Argon (servo drive) has internal power supply bleeding resistor that will discharge the capacitors during 5 minutes after AC power has been removed.
To safely discharge Argon voltages:
- Remove AC power (both L and N lines). This can be done for example by unplugging the power cord from wall socket where the power comes from.
- Wait 5 minutes after removing AC to allow capacitor voltage discharge.
Discharging 24 VDC supply does happen instantly after 24 V has been removed. However, this does not affect AC side discharge in any way.
