Description of the options
With option
K82
, the requirements specified in EN 61800-5-2,
EN 60204-1, DIN EN ISO 13849-1 Category 3 (previously
EN 954-1) as well as Performance Level (PL) d and IEC 61508
SIL 2 are fulfilled. The Safety Integrated functions using option
K82
are only available in conjunction with certified components
and software versions.
The following Safety Integrated functions are controlled using
option
K82
:
•
Safe Torque Off (STO)
•
Safe Stop 1 (SS1)
(time-controlled)
With the Motor Modules in chassis format, option
K82
cannot be
ordered together with option
L55
(cabinet anti-condensation
heating).
L08 Motor reactor
Motor reactors reduce the voltage stress on the motor windings
by reducing the voltage gradients at the motor terminals that oc-
cur when motors are fed from drive converters. At the same time,
the capacitive charge/discharge currents that occur at the con-
verter output when long motor cables are used are reduced. Sui-
tably dimensioned motor reactors or series connections of motor
reactors therefore offer a solution which allows a higher capaci-
tance and thus also longer motor cables to be connected. It is
generally recommended that motor reactors are used in the
case of multi-motor drives. With option
L08
for Motor Modules, a
motor reactor is integrated, fully wired, into the Motor Module up
to cabinet size GX (outputs of less than 315 kW). Due to space
constraints, a separate cabinet must be planned for the output
range 315 to 450 kW (cabinet size HX;
see
Motor Double Choke Module
).
L25 Circuit breaker in a withdrawable unit design
Line Connection Modules with an input current of > 800 A are
equipped with fixed-mounted circuit breakers as standard.
Where the customer requires a visible isolating distance, a
withdrawable circuit breaker can be ordered as an option.
L37
DC interface incl. pre-charging circuit of the relevant DC
link capacitance
If, for reasons relating to the process or availability, the Motor
Module needs to be disconnected from or connected to the
common DC link for an entire drive line-up during operation,
a manually operated isolating distance can be ordered as an
option. With chassis format power units, this takes the form of
switch disconnectors. Option
L37
is installed on the busbar
between the Motor Module and the main DC busbar. This option
also includes a pre-charging switch for the DC link capacitors of
the relevant Motor Module so that it can be switched in to the
pre-charged DC link. The switching operation is performed
externally. The operating levers can be locked using a padlock
(padlock not included in scope of delivery). The degree of
protection of the cabinets is not affected.
L42 Line Connection Module for Active Line Modules
Option
L42
is specified in the order to indicate that the Line
Connection Module will be connected to an Active Line Module.
The Line Connection Module is then adapted accordingly
(pre-charging circuit, connection busbars, etc.). Also refer to
the assignment table in the "Line Connection Modules".
L45 EMERGENCY OFF pushbutton in cabinet door
The EMERGENCY OFF pushbutton with protective collar is
installed in the cabinet door of the Line Connection Module and
its contacts are connected to a terminal block. From here, the
EMERGENCY OFF pushbutton can be integrated into the plant-
side EMERGENCY OFF chain.
L55 Cabinet anti-condensation heating
The anti-condensation heating is recommended for low ambient
temperatures and high levels of humidity to prevent condensa-
tion. Depending on the cabinet width, a 100 W cabinet heater is
installed for each Cabinet Module. One heating element for ca-
binet width up to 600 mm, 2 heating elements for cabinet width
over 800 mm. The power supply for the anti-condensation hea-
ting (110 to 230 V AC, at terminal block -X240) must be provided
externally and fused with max. 16 A. Within the transport units,
the heaters are internally connected and must only be fed once.
Option
L55
cannot be ordered together with option
K82
(termi-
nal module for the control of safety functions).
L87 Insulation monitoring
An insulation monitor must be used if the converter is operated
on an isolated supply system. The device monitors the entire
galvanically coupled circuit for insulation faults. An alarm is out-
put by the insulation monitor in the event of a fault.
Notice
:
Only one insulation monitor can be used within the same electri-
cally connected supply system. As there are different response
strategies when a ground fault occurs in an isolated supply sys-
tem, output relays of the insulation monitor are provided for inte-
gration in a line-side control. It is also possible to integrate the
outputs into the monitoring system of the Cabinet Modules on
the line side.
M06 Base 100 mm high, RAL 7022
The additional cabinet base allows larger bending radii for
cables (cable inlet from below) and enables them to be routed
within the cabinet base. The cabinet base is supplied in
RAL 7022 in all cases. A special paint finish is not available for
the base. It is delivered completely assembled with the cabinet.
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.
Notice
:
The cable compartment is painted as standard with RAL 7035.
If a special color is requested for the cabinet (option
Y09
), the
cable compartment is also painted in this color.
