1)
At the mounting version for the controls HP5, HP6 and EP5, EP6, the
cast-in port designations A and B on the counterbalance valve BVD
do not correspond with the connection drawing of the A6VM motor.
The designation of the ports on the installation drawing of the mo-
tor is binding!
2)
Momentary pressure spikes may occur depending on the application.
Keep this in mind when selecting measuring devices and fittings.
3)
The spot face can be deeper than as specified in the standard.
O = Must be connected (plugged on delivery)
X = Plugged (in normal operation)
