Connecting the unit
Observe the following points for hydraulic connection:
All hoses on the power unit must be sufficiently conductive in
regard to electrostatic charge build-up.
If hoses are used, the ohmic resistance between the fittings, in
this case between the power unit and the tank, may not exceed a
limit value depending on the respective hose type.

Marking the hose with the symbol "M" :
Limit value ≤ 10
2

Marking the hose with the symbol "

" :
Limit value ≤ 10
6

The hose connection must ensure a highly conductive transition
between the hose and power unit, as well as between the hose
and reservoir.
If this is not the case, all conducting parts (such as the metal
mouth piece at the end of the hose) are to be grounded
separately.
Connecting conductive hoses with fittings to hose tubes requires
marking and checking per DIN EN 12 115.
Connect the ground clamp of the unit to a suitable grounding
source nearby.
