ELECTRICAL INSTALLATION

DANGER
Danger to life from electric shock - Personnel qualification
DANGER
Danger to life due to defective, dismantled and manipulated protective devices
Remove sealing plug
For transport, the pressure connection is protected against the ingress of
dirt and foreign bodies with a sealing plug. This must be removed before
commissioning.
Dimensioning of the pressure line
Make the pipes at least the same diameter as the nominal connection
size.
For cable lengths > 2 m, the next larger cross-section must be
selected.
For pipe lengths > 5 m we recommend the additional installation of
non-return valves.
Keep connections free of oil, grease, water and other contamination.
The supply line must be installed mechanically stress-free by means of a
flexible hose or fixed pipe.
Setting the pressure
The pump is usually equipped with a pressure regulating valve, which
allows the pressure required for the application to be set.
Depending on the size and variant, this value is limited. (chap. 9.2)
