Siemens AG 6SE7087-6KP50
SIMOVERT MASTERDRIVES Operating Instructions 7-1
7 Connecting-up
SIMOVERT MASTERDRIVES units are operated at high voltages.
The equipment must be in a no-voltage condition (disconnected from
the supply) before any work is carried out!
Only professionally trained, qualified personnel must work on or with
the units.
Death, severe bodily injury or significant property damage could occur if
these warning instructions are not observed.
Hazardous voltages are still present in the unit up to 5 minutes after it
has been powered down due to the DC link capacitors. Thus, the
appropriate delay time must be observed before working on the unit or
on the DC link terminals.
The power terminals and control terminals can still be live even when
the motor is stationary.
If the DC link voltage is supplied centrally, the converters must be
reliably isolated from the DC link voltage!
When working on an opened unit, it should be observed that live
components (at hazardous voltage levels) can be touched (shock
hazard).
The user is responsible that all the units are installed and connected-up
according to recognized regulations in that particular country as well as
other regionally valid regulations. Cable dimensioning, fusing,
grounding, shutdown, isolation and overcurrent protection should be
particularly observed.
