DANGER

 

Risk of explosion! 

If the pressure monitoring system is bridged for maintenance/service work, the 
device can be operated permanently without compressed air purging and 
overpressure. 

There is no protection against explosions! 

 

Bridging only for service and maintenance work! 

 

Bridging only by authorised trained staff! 

 

Use suitable measures /warnings to prevent permanent operation!
