Out of Service
1. ensure standstill of the drive – frequency inverter
2. deactivate control – R4-S-regenerative unit, terminal ST
3. disconnect mains – main contactor
Demounting
When demounting the R4-S-regenerative unit please pay special attention to
the capacitor discharge time!
Before starting to work, the safe isolation from supply must be verified with
measurements in the system!
All installation and connection work must be done when the system is switched
off!
The intermediate circuit capacitors are still charged with high voltage for a short
period of time. The unit can be worked on again, after it has been switched off for
5 minutes.
Waste Disposal
The R4-S-regenerative unit does not contain PCB elements.
The waste disposal items must be given to a special waste disposal!
