7. INSTALLATION
Before installing and setting up the gear reducer, proceed by following all the items of the following checklist:
Check the nameplate data of the gear reducer and, if needed, of the electric motor;
Make sure the equipment supplied corresponds to the equipment ordered;
Make sure that the category of the equipment is suitable for the environmental classification in which it will be
installed and subsequently operated;
The fastening of the machine to the structure must be stable and without any vibrations. The structure must not be
subject to torsional movements;
For the fastening use screws with a minimum resistance class of 8.8, without deforming the case due to incorrect
fastening (see the table with the TIGHTENING TORQUES FOR FIXING SCREWS). In threaded joints we recommend
using thread locking liquids to prevent loosening due to vibrations. Always check the correct tightening after the first
hours of operation.
Make sure the supporting surface is flat and large enough to fit the whole gear reducer;
Make sure the operating position matches the mounting position reported on the nameplate;
Check the position of the oil level plug, which must always be clearly visible for periodic inspections even after fitting
the gear reducer on the machine. Make sure the oil drain/filler plugs are accessible.
Make sure the gear reducer has been filled with the right amount of oil according to the required mounting position;
Replace the closing plug, if present, with the breather plug in the kit provided with the gear reducer;
Check for any lubricant leakages. If there are any, interrupt the installation, identify the leak and contact
MOTOVARIO’s TECHNICAL SERVICE;
Remove any traces of dirt or dust from the shafts and from the areas around the sealing rings;
Lubricate contact surfaces to prevent oxidation or seizure;
Check the static seals and the bolted joints;
Do not install the unit in an environment with fumes or abrasive and/or corrosive dust, or in environments with
ionising radiation;
Install all the protections designed for the rotary parts to ensure the system is safe, in accordance with current
regulations;
Check the correct direction of rotation of the output shaft of the unit;
In case of shaft mounting, it is recommended to use Motovario torque arms;
Ensure proper cooling of the motor through a good flow of air from the fan side;
Avoid solar radiation or irradiation from other heat sources. The cooling air temperature must never exceed 40°C or
drop below -20°C;
Check that the assembly of the various parts (pulleys, sprockets, couplings, etc.) on shafts is performed by using the
relevant threaded holes or any other system able to ensure a correct operation without damaging the bearings or the
outer parts of the gear reducer, see paragraph 8 for details. SPECIFIC ASSEMBLIES.
Ensure an equipotential bond (earthing) of the gear reducer case by using one of the free holes previously cleaned to
remove oxides or paint. The electrical connection must be carried out in accordance with EN standard 60079-0
“Paragraph 15 – Connection facilities for earthing or bonding conductors”. The cable section must comply with Table 10
and in any case must not be less than 4 mm

.
In case of ambient temperature not listed in the table LUBRICANTS RECOMMENDED BY MOTOVARIO, please contact
MOTOVARIO TECHNICAL SERVICE. If the temperature is lower than -30°C or higher than 60°C use special mixture
sealing rings.
