In case of installation outdoors and when fitted with an electric motor, protect the latter from
direct sunlight and the weather by means of guards or a casing. Also make sure that the
assembly is properly ventilated.
Check on the gear unit nameplate that the configured mounting position corresponds to the
position specified in the order.
Now proceed with the installation as follows:
Place the gear unit in the vicinity of the installation area.
Mount the gear unit and secure it to the structure at the points provided. The gear unit should be
secured to the structure through all mounting points on the mount specified (feet or flange).
Tighten the anchor bolts only after having obtained an extensive contact zone between
the gear unit base and the foundation or between the connecting flanges.
After having tightened the fixing bolts check the alignment of the shafts again; said alignment
must also be checked and, if necessary, corrected after a few days of operation.
If the gear unit is supplied full of lubricant, identify the closed type plug utilised for transport
(usually red) and replace it with the breather plug supplied with the unit.
Tighten down the mounting bolts and check that the oil plugs are screwed down to the torque
given in table (A0).
