product from all voltage sources before starting to open.
The detachable power cord is the instrument disconnecting device. It disconnects the main

The power cord is connected to internal capacitors that may remain live for 5 seconds after
disconnecting the plug from its power supply.

power cord). The mains plug shall only be inserted in a socket outlet provided with a protective
earth contact. Any interruption of the protective conductor inside or outside of the product is
