EMERGENCY STOP shutdown (main switch)
For shutdown in the event of an emergency, an emergency stop must be present and freely accessible at all
times.
4.6.2
Maintenance and repair switch
To safely exclude the possibility of unexpected machine start-up, a maintenance and repair switch must be
installed in the immediate vicinity of the electric drive so that the electrical power can be safely isolated for
maintenance purposes.
The maintenance and repair switch must be secured in its OFF position to prevent it being switched back on
again, using a padlock for example.
WARNING
Qualified technical personnel must connect and check the safety devices on a regular basis for proper
function, especially after performing maintenance and repair work and before start-up.
