Mechanical Installation
4.1
Before you begin
The drive may
only be installed
if
•
The entries on the nameplate of the drive and/or the output voltage of the frequency
inverter match the voltage supply system
•
The drive is undamaged (no damage caused by transportation or storage)
•
It is certain that the following requirements have been met:
– Ambient temperature between –20 °C and +40 °C
1)
– No oil, acid, gas, vapors, radiation, etc.
– Installation altitude max. 1000 m above sea level
– Note the restrictions for encoders
– Special versions: Drive configured in accordance with the ambient conditions
4.2
Preliminary work
Motor shaft ends must be thoroughly cleaned of anti-corrosion agents, contamination or
similar (use a commercially available solvent). Do not allow the solvent to penetrate the
bearings or shaft seals – this could cause material damage!
Extended storage
of motors
•
Please note the reduced grease utilization period of the ball bearings after storage
periods exceeding one year.
•
Check whether the motor has absorbed moisture as a result of being stored for a long
time. Measure the insulation resistance to do this (measuring voltage 500 V).
The insulation resistance (
→
following figure) varies greatly depending on the
temperature! The motor must be dried if the insulation resistance is not adequate.
It is essential to comply with the safety notes in Section 2 during installation!
1) Minimum temperature for motors with backstop: –15 °C. Note that the temperature range of the gear unit
may also be restricted (
