Pressure limitation
If there is a risk for pressure peeks over 350 bar in the hydraulic system, a cross-over
valve must be installed to limit the pressure level.
Voltage equalization
The Hägglunds hydraulic motor must be connected to external ground for voltage
equalization. The grounding point of the Hägglunds hydraulic motor is on one of
the screws for port connection as per Fig. 3. Minimum required cable area for
equalization connection is 10 mm

The parts for grounding (washers, screws and terminal lug) are delivered in a small
bag attached to the motor. The bag contains parts to fit all motor types so all parts
will not be used. Cable is not included in the delivery.
It is important to follow the grounding point examples for each motor type. Flange for
connection can be selected to best fit the installation.
