DANGER
Bypassing the protective device
The dangerous state may not be stopped in the event of non-compliance.
b
If a cascade is created with directly connected safety switches, connecting cables
must be mounted so that a safety switch cannot be easily jumpered; e.g., cover
plug connectors or protect against access with additional means (e.g., protective
cover with disposable screws)
