Product- and Technology-dependent Safety Instructions
WARNING
Pressurized system!
Danger to life, risk of injury, severe injury when working on systems that have
not been stopped! Damage to property!
●
Ensure that the DRn system and/or the machine is completely depres‐
surized.
●
Do not disconnect line connections, connections or components as long
as the DRn system is pressurized.
●
Switch off all force-transmitting components and ports (electric, pneu‐
matic, hydraulic) according to the manufacturer's specifications and se‐
cure them against restarting. If possible, remove the mains fuse of the
system.
WARNING
Leaking oil mist due to defective or improperly assembled seals!
Risk of fire, risk of explosion, danger due to allergic reactions, environmental
pollution!
●
Welding work may only be carried out when the DRn system is depres‐
surized.
●
Keep open fire and ignition sources away from the DRn system.
WARNING
High electrical voltage (above 50 V)!
Danger to life, risk of injury caused by electric shock or severe injury!
●
Make sure the relevant system part is de-energized before assembling
the DRn system or connecting and disconnecting connectors.
●
Protect the system against restarting.
●
Only carry out short-time measurements and tests with permanently
connected protective grounding conductor at those points of the compo‐
nents intended for this purpose.
●
After switch-off, you should generally wait for 30 minutes before you
touch an electric component in order to allow the live capacitors to dis‐
charge. Measure the electrical voltage of live parts before beginning the
work in order to avoid hazards caused by contact.
●
Do not touch the electrical connection points of the components if the
system is activated.
