L84
Thermistor motor protection unit (trip)
Thermistor motor protection device for single-channel PTC tem-
perature sensors (PTC resistors, type A) for trip.
The thermistor motor protection unit is supplied with power and
evaluated internally in the converter. There is galvanic isolation
between the supply voltage and the temperature measuring cir-
cuit.
Note:
The Control Unit has a monitoring channel to monitor the motor
temperature as standard. This single-channel input supports
PTC, KTY84, Pt1000 and also thermoclick sensors. The warning
and fault thresholds are parameterizable. The temperature val-
ues acquired are automatically used for high-precision motor
control.
Caution:
If there is no 230 V AC power supply in the customer installation,
it is essential to select option
K74
in order to ensure proper func-
tioning of option
L84
.
L86
PT100 evaluation unit
The Pt100 evaluation unit can monitor up to 6 temperature sen-
sors. The following sensor types are supported: Pt100, Pt1000,
KTY84, NTC and thermocouples.
The sensors can be connected in a two- 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 3 channels. With motors, for example, this
means that three Pt100s in the stator windings and two Pt100s in
the motor bearings can be monitored. Unused channels can be
suppressed via parameters.
The output relays are integrated into the internal fault and shut-
down sequence of the converter. There is galvanic isolation be-
tween the supply voltage and the temperature measuring circuit.
The Control Unit has a monitoring channel to monitor the motor
temperature as standard. This single-channel input supports
PTC, KTY84, Pt1000 and also thermoclick sensors. The warning

ues acquired are automatically used for high-precision motor
control.

M06
Base 100 mm high
The additional cabinet base allows larger bending radii for ca-
bles (cable entry from below) and enables them to be routed
within the cabinet base. It is delivered completely assembled
with the cabinet. The mounting height of the operator panel
changes accordingly.
M07
Cable compartment 200 mm high, RAL 7035
The cable compartment 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 compartment. It is delivered
completely assembled with the cabinet. The mounting height of
the operator panel changes accordingly.
Note:
The cable compartment is coated as standard in RAL 7035.
M21
IP21 degree of protection
For converter cabinet units up to a rated power of 132 kW,
the height of the cabinet does not increase as a result of the
increase in degree of protection.
In the case of converter cabinet units with a rated output of
160 kW and above, the cabinet height is increased by 300 mm
(11.81 in) with a raised roof or drip plate.
For transport reasons, the top or drip protection covers are
delivered separately and must be fitted on site.
Note:
The top or drip protection covers are painted in RAL 7035 as
standard.
Caution:
If there is no 230 V AC power supply in the customer installation,
it is essential that option
K74
be selected in order to ensure
power supply to the fan for frame sizes F, HX (version A) and JX.
M23, M43, M54
Degrees of protection IP23, IP43, IP54
For converter cabinet units up to a rated power of 132 kW,
the height of the cabinet does not increase as a result of the
increase in degree of protection.
For converter cabinet units with a rated output of 160 kW or
higher, the cabinet height is increased by 400
mm (15.7 in) when
the options
M23
,
M43
or
M54
are selected.
For transport reasons, the hoods are delivered separately and
must be fitted by the customer.
Note:
The roof sections are colored RAL 7035 as standard. The
molded plastic parts (e.g. ventilation grilles) have color
RAL 7035 and cannot be coated.
Notice:
If there is no 230 V AC power supply in the customer installation
for version A, it is essential to select option
K74
in order to pro-
vide a power supply to the fan.
