Argon user guide/Power supply safe discharging
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.
