Drive converter cabinet units
75 kW to 2700 kW
L84
Thermistor motor protection device (trip)
Thermistor motor protection device for PTC thermistors (PTC re-
sistors, type A) for trip. The thermistor motor protection device is
supplied with power and evaluated internally in the converter.
L86
Pt100 evaluation unit
The Pt100 evaluation unit can monitor up to six sensors. The sen-
sors can be connected using a two-wire or three-wire system.
The limit values can be freely programmed for each channel.
In the factory setting, the measuring channels are subdivided
into two groups, each with three channels. With motors, for ex-
ample, this means that three Pt100s in the stator windings and
two Pt100s in the motor bearings can be monitored. Unused
channels can be hidden via parameters.
The output relays are integrated into the internal fault and shut-
down sequence of the converter.
L87
Insulation monitoring
An insulation monitor must be used if the converter is connected
to an ungrounded line supply. The device monitors the entire
galvanically coupled circuit for insulation faults.
An alarm is output in the event of a fault.
Notice:
Only
one
insulation monitor can be used in each galvanically
coupled network.
As there are different response strategies when a ground fault
occurs in an ungrounded system, output relays of the insulation
monitor are provided for integration in a plant-side control. It is
also possible to integrate the outputs into the converter monitor-
ing system on the plant side.
Insulation monitoring can be supplied on request for converter
cabinet units with power units connected in parallel.
M06
Base 100 mm high, RAL 7022
The additional cabinet base allows larger bending radii for ca-
bles (cable inlet from below) and enables them to be routed
within the cabinet base.
The cabinet base is supplied in RAL 7022 as standard. A special
paint finish is not available for the base. It is delivered completely
assembled with the cabinet. The height of the operator panel
changes accordingly.
M07
Cable marshalling space 200 mm high, RAL 7035
The cable marshalling space is made of strong sheet steel and
allows cables to be connected more flexibly (entry from below).
It also allows routing of cables within the marshalling compart-
ment. It is delivered completely assembled with the cabinet. The
height of the operator panel changes accordingly.
Note:
The cable compartment is painted as standard with RAL 7035.
If a special color is requested for the cabinet (order code
Y09
),
the cable-marshaling space is also painted in this color.
M13
Line connection from above
The control cabinet is provided with an additional roof section to
allow a line connection from above. The connection lugs for the
power cables, the clamping bar for mechanically securing the
cables, an EMC shield bus, and a PE busbar are located within
this roof section.
This increases the cabinet height by 405 mm. The busbars for
the connection from above are delivered completely pre-in-
stalled. For transport reasons, the roof sections are delivered
separately and must be fitted on site. Crane transport assem-
blies (option
M90
) can still be used.
However, they must be removed on site before the roof sections
can be installed. Use of rope spreaders should be considered in
the case of small crane hook heights.
An undrilled aluminum mounting plate (5 mm thick) is provided
in the roof section for feeding in the cables. Depending on the
number of cables and the cross-sections used, holes for attach-
ing cable glands for feeding in the cables must be drilled in this
mounting plate on site.
Notice:
The control cables are still connected from below. When option
M13
is selected, the standard line connection from below is omit-
ted.
The degree of protection of the roof sections is IP21. In combi-
nation with options
M23, M43
and
M54
, additional plastic venti-
lation grilles and filter elements are provided.
Note:
The roof sections are painted in RAL 7035 as standard. If a spe-
cial color is requested for the cabinet (order code
Y09
), the roof
sections are also painted in this color. Ventilation grilles used
with IP23, IP43 and IP54 degrees of protection are in RAL 7035
and cannot be painted.
Option
M13
is not available for converters > 1500 kW with power
units connected in parallel.
