riod of time
WARNING
Improper handling of the system can result
in serious or fatal injuries!
Have you read the safety notes in chapter
1
Safety, page 5 f.?
If not then you are not allowed to carry out any
work on or with the system!
WARNING
Risks of burns and scalding from hot sur-
faces on the unit.
• Before working on the unit, allow the system
to cool down for at least 30 min after shutting
it down!
When shut down for longer periods
from about 4 weeks) the system can:
•

be sent to store.
8.1 Storage conditions
To avoid damage when stored for some time, the
environment must be:
• dry,
• free of dust,
• subject to low oscillations (effective value for
the speed of oscillation v
eff
≤ 0.2 mm/s
[0.008"/sec]).
8.2 Commissioning after a long shutdown
period
Commissioning after a long shutdown period:
• Measuring the motor insulation resistance.
For values ≤ 1kΩ per volt measured voltage
dry the coil.
• For new systems:
-
Install the system (chapter 5, page 9).
• Start up the system (chapter
6, page 12).
