SIMOVERT MV Commissioning Instructions
4.2.3
Safety circuit
The drive converter is equipped with a safety circuit. The drive converter is fault
tripped if this safety circuit is interrupted. It is sub-divided into an external and
internal safety circuit (details, refer to Section 3.1.1).
The internal safety circuit includes:
♦
Safety pushbutton in the door (mushroom head pushbutton)
♦
Contact on the MM3 module in the SIMADYN D subrack
♦
Binary output 2 of the SUL module in the CCU subrack
♦
Door contact of the power cabinet
♦
Overpressure switch, filter capacitor -C10, -C11
The external safety loop can include, depending on the particular application case,
enable signals or interlocking signals from options or system-specific signals.
These are linked-in by removing the jumper X100:A16 - X100:C16 and connecting
to these terminals.
4.2.4
Fault shutdown
Every fault shutdown causes the crowbar thyristor to be released and a message
displayed on the OP2. The thyristors of the crowbar thyristor can only be
controlled, if the DC link voltage has exceeded approx. 600 V.

During operation, drive converters can have live, bare, and also moving or rotating
parts as well as hot surfaces, corresponding to their degree of protection.
Severe personal injury or material damage can occur if the required covers are
inadmissibly removed, if the equipment is incorrectly used or is incorrectly installed
and handled.
Additional information is provided in the documentation.

may be employed to transport, install and
start-up (commission) and service the equipment (observe IEC 364 and CENELEC
HD 384 or DIN VDE 0100 and IEC Report 664 or DIN VDE 0110 and the domestic
accident prevention regulations).
In the sense of basic safety information, qualified specialist personnel are those
personnel who have the training knowhow and qualifications to install, mount,
commission and operate the equipment
The fault is displayed with a fault number and fault message text on the operator
panel display. Refer to the Instruction Manual for troubleshooting and a description
of the individual faults.

An insulation monitoring function for the complete circuit is included it the
converter.

When a ground fault occurs, significant capacitive re-charging currents can flow as
a result of the operating mode. These currents can result in subsequent damage.
We recommend that the power circuit of the SIMOVERT-MV drive converter is
disconnected when a ground fault occurs.
