actuated in case of an emergency.
Unplug the device from the electrical outlet before performing
the following work:
removing or installing power supply units
working in the immediate vicinity of exposed power supply
parts
mechanical inspection of power supply parts
modifying the device circuits.
Ensure that the device is de-energized.
Check the workplace for possible sources of danger, e.g. moist
floors, defective extension cables, faulty protective conduction
connections.
Give another person the task of remaining near the workplace.
This person must be familiar with the location and operation of
the emergency-stop and power switches and switch off the
