WARNING!
Risk of injury due to electric shock!
` Before reaching into the device or the equipment, switch off
the power supply and secure to prevent reactivation!
` Observe the applicable accident prevention and safety regu-
lations for electrical equipment!
Risk of injury due to high pressure in the system!
` Turn off the pressure and vent the lines before loosening lines
or valves.
