Electrostatic Discharge Hazards
Electronic equipment is sensitive to static electricity. To protect these components from damage
caused by static electricity, special precautions must be taken to minimize or prevent
electrostatic discharge.
Observe these safety precautions while you work with the equipment or in its vicinity.
–
Before performing maintenance or repair work, ensure that the static electricity inherent to
your body is discharged.
–
Do not wear clothing made from synthetic materials to prevent static electricity from
building up. Your clothing should therefore be made of cotton or cotton mix materials.
–
Keep plastics such as vinyl and Styrofoam materials as far away from the control system, the
modules, and the work environment as possible.
–
Do not remove the circuit boards from the housing of the device.

Special Safety Instructions for the Device
Explosion hazard!
When the system is powered up, do not remove any connectors unless the
system is not located in a potentially explosive atmosphere.
Explosion hazard!
If the system is not entirely tight and sealed, gas may escape and lead to an
explosion hazard. Upon completion of all assembly works, always check the
system's tightness. Also ensure that the gauge port on the VariFuel2 is
closed.
All works involving gas-carrying parts must be executed by trained
personnel only.
Operational safety!
All screws of the connectors must be adequately tightened.
