You will find a suitable safety locking for every machine or system.
Especially when machines or industrial plants are in maintenance or servicing mode by technicians or engineers, it is necessary to secure them from access.
Depending on whether you want to partially or completely lock a system or machine from access by your employees, there is a corresponding locking. For industrial plants, this allows you to decide whether you want to shut down the main switch and thus the complete machine for the maintenance period. Or whether it is sufficient to disconnect individual electrical fuses.
