4.2 Installation requirements
Make sure that the following requirements are met before you start installing the unit:
• The drive has not been damaged during transportation or storage.
• The entries on the nameplate of the gearmotor match the voltage supply system.
• When the unit is installed in abrasive ambient conditions, protect the output end oil
seals against wear.
• The output shafts and flange surfaces must be completely free from anti-corrosion
agents, contamination or similar. Use a commercially available solvent for cleaning.
Do not expose the sealing lips of the oil seals to the solvent – damage to the material.
