7. INSTALLATION
Pay special attention to the installation conditions as these are the main cause of damage and downtime. When choosing
the motor, consider the mounting position and presence, below the motor itself, of parts, things or materials which may be
damaged by oil leaks, however limited in amount. Choosing the right mounting position can eliminate many problems. It is
often sufficient to place a guard under the motor to ensure operation in optimal safety.
The unit can only be mounted in the mounting position indicated on the nameplate: a different mounting
position must be authorised by Motovario. Changes in angle or inclination with respect to the horizontal are
allowed by +/-5°.
Before the commissioning of the unit, carry out the following operations:
Check the nameplate data of the unit and/or electric motor;
Check that the supply corresponds to what was required by the order;
Fixing to the structure of the machine must be stable, vibration-free. The structure shall not be subject to torsional
movements, must ensure a continuity of transmission of any electrical and electrostatic charges. Otherwise provide a
grounding system, via a cable securely attached to the mounting areas, making sure to remove any paint in the
contact area and using conductors of adequate cross section;
For fixing use the fixing screws of minimum 8.8 quality and be sure not to buckle the casings due to improper fixing,
making sure that the support surface is coplanar to the fixing surface (refer to FIXING SCREW TIGHTENING TORQUE
table);
Do not install the unit in mounting positions other than those stated in the order, since different positions provide
different positions of the loading, unloading and oil level caps, in addition to a different amount of lubricant, if
indicated/present;
Check the position of the level cap. If the casing is provided with a hole closed with cap symmetric with respect to
the level cap itself, if necessary, for level visibility, reverse their positions. Check the accessibility to oil
loading/unloading caps.
Check, if possible, the correct quantity of oil, according to the mounting position required. If the oil level of the unit is
restored, do it according to the cap diagram and use oil of the same type indicated on the label.
Replace, if any, the closing cap with the vent cap provided in the supplied kit;
Check for any leakage of lubricant;
If possible, remove any traces of dirt from the shafts and from the areas around the sealing rings;
Lubricate the 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;
Do not install the unit in direct contact with food products in bulk. Occasional contact with foodstuff is allowed only
with series SWFX gearmotors;
Install all the protections designed for the rotary organs so as to ensure the system safety according to the current
rules;
Check for the correct rotation direction of the output shaft of the unit;
In case of shaft-mounted configuration it is recommended to use the torque arms that can be supplied by Motovario,
specially designed;
Ensure proper cooling of the motor through a good flow of air from the fan side;
Avoid solar radiation or other heat sources, the cooling air temperature must never exceed 40°C;
Check that the assembly of the various parts (pulleys, sprockets, couplings, etc.) on shafts is performed by using the
proper threaded holes or any other systems able to ensure a correct operation without risking damage to the
bearings or the outer parts of the units.
For the operating fields with temperatures below 0°C, please consider the following:
For the gear reducers, please contact MOTOVARIO TECHNICAL SERVICE beforehand;
The motors must be suitable for operation with the expected ambient temperature;
The electric motor power must be adjusted when exceeding the higher starting torques required.
In addition for variators:
The change in revolutions, using the appropriate command, must be executed solely when the unit is running;
There must be an oil seal in the coupling area between the variator and the motor.
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.
