Siemens AG 6SE7087-7KN50
SIMOVERT MASTERDRIVES
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.
Only create electrical connections if the unit is in a no-voltage condition!
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.
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.
The inverters are suitable for connection to
♦ rectifier units,
♦ rectifier/regenerative feedback units and
♦ self-commutating rectifier/regenerative feedback units (AFE), which
are fed from systems with or without grounded neutral point (TN
systems and TT systems or IT systems according to EN 60364-3).
The inverters are dimensioned for overvoltage category III according to
IEC 60664-1.
In systems with grounded phase conductor and a line voltage
> 600 V AC measures should be provided on the plant side to limit any
overvoltages occurring to overvoltage category II according to
IEC 60664-1.
