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!
