• Motor shaft ends and flange surfaces must be thoroughly cleaned of anti-corrosion
agents, contamination or similar. Use a commercially available solvent. Make sure
that the solvent does not come into contact with the bearing or sealing rings as it
may damage the material.
• Make sure the customer's counter-bearing is unobstructed and can move freely.
• Provide for sufficient clearance around the motor to allow for adequate cooling.
• Make sure that it does not reuse the exhaust air warmed by other devices.
• Balance components for subsequent mounting on the shaft only with a half key
(motor shafts are balanced with a half key).
• Turn the rotor by hand and listen for unusual grinding noise.
• Check the direction of rotation in decoupled state.
4.2.1 Installation in damp locations or in the open
• Try to arrange the motor and encoder connection so that the connector cables do
not point upwards.
• Clean the sealing surfaces of the connector (motor or encoder connection) before
reassembly.
• Replace any brittle seals.
• Check that the degree of protection is maintained.
• If necessary, attach covers (protection canopy).
