Connect the functional earth

WARNING!
Risk of ignition and risk of fire that are due to electrostatic discharge.
An electrostatic discharge of the device can ignite combustible gas vapours.
To avoid a build up of electrostatic charge, connect the housing to the functional earth.
If the functional earth is not attached, then the requirements of the EMC directive are not met.
Use a green-and-yellow cable that is as short as possible. And the cable cross-section must be at least
equal to the cross section of the power-supply cable.
With a flat screwdriver of size 6.5 mm, loosen the M4 screw.
Fig. 10: Location of the M4 screw for the connection of the functional earth
Attach the green-and-yellow cable to the M4 screw with a cable lug.
Tighten the M4 screw to a torque of 1,8 N·m...2 N·m (1,33 lbf·ft...1,47 lbf·ft).
