Danger!
Hazardous voltage on the power connections even when disconnected from
mains: residual voltage >60 V!
Before working on the power connections, always disconnect the drive
component from the mains and wait until the motor is at standstill.
Verify safe isolation from supply!
Shaft sealing rings and rolling−contact bearings have a limited service life.
8.2 Maintenance intervals
Inspections
ƒ If the machine is exposed to dirt, clean the air channels regularly.
ƒ Check the power supply cables on a regular basis.
Motor
ƒ Only the bearings and shaft sealing rings become worn.
– Check bearings for noise (after approx. 15,000 h at the latest).
ƒ In order to prevent overheating, remove dirt deposits on the drives regularly.
ƒ We recommend carrying out an inspection after the first 50 operating hours. In this
way, you can detect and correct any irregularities or faults at an early stage.
