The compressed air shut-off valve on
the maintenance unit interrupts the air
supply to the entire machine.
The machine will stop immediately.
The functional principle:
➤
Open
Position ball valve in the
flow direction
➤
Close
Position ball valve trans-
verse to the flow direction
After the air has been shut off the
equipment will be vented automati-
cally. However, some pressure may
remain in the material. Carry out a
complete pressure release before
starting any work on the equipment!

2.4.3 Ground cables
In order to prevent an electrostatic charging, the machine must be grounded.
The ground cables for all components
for which grounding is required are
merged into the grounding terminal.
In order to ground the machine,
connect the main ground cable first
to clamp 1 of the grounding terminal
and then to an electrically conductive
object outside hazardous areas.

If an ground cable is lost or defective, it must be replaced immediately!
