Oil expansion tanks (Option OA) must be fitted in accordance with works standard WN 0-530 04.
For M10x1 screw fixings, the attached works standard WN 0-521 35 must also be observed.
The pressure vent must be activated prior to commissioning. To activate, remove the transport
securing devices.
Double gear units consist of two single units and are equipped with 2 oil chambers and 2
pressure vents. Position of the vent plug: see Section 6.1.

3.7 Installing the gear unit
The base and/or flange to which the gear unit is fitted should be vibration-free, torsionally rigid
and flat (flatness error <0.2 mm). All contamination to the bolting surfaces of gear unit and base
and/or flange must be thoroughly removed.
The gear unit housing must always be earthed. With geared motors, earthing via the motor
connection must be ensured.
The gear unit must be installed in the correct configuration (See Section 3.5 and 6.1). All
gear unit feet and/or all flange bolts on each side must be used. Bolts must have a minimum
quality of 10.9. The bolts must be tightened to the correct torques (refer to Section 6.3 for torque
values). Tension-free bolting must be ensured, particularly for gear units with a foot and flange.
The oil inspection screws, oil drain screws and the vent valves must be accessible.
To ensure that the gearbox does not get too warm and to avoid injury to persons, observe
the following during installation:
Danger!
The eyebolts screwed into the gear units must be used during installation. During
installation, no additional weights may be attached to the gear unit. If geared motors
have an additional eyebolt attached to the motor, this must also be used. Avoid pulling
the eyebolts at an angle.
Danger!
No explosive atmosphere must be present when installing the gear unit.
Danger!
The surfaces of gear units or geared motors may become hot during or shortly after operation.
Attention: danger of burns! Protection against accidental contact may need to be installed.
