Options

L49
Grounding socket outlet 230 V, 50 Hz, 1 A, in control cabinet
with 30 mA ground-fault circuit interrupter, supplied internally
Option
L49
comprises one 230 V/50 Hz grounding socket outlet
in the control cabinet with a 30 mA ground-fault circuit inter-
rupter and 1 A /C miniature circuit breaker, e.g. for notebook
(service).
The socket outlet is supplied from an internal
control transformer.
If a plug system other than the SCHUKO grounding system is
used, e.g. a British or US plug system, please specify this in the
order.
L50
Magnetically attached control cabinet light and
door contact switch
L50
Control cabinet light (example shown)
The light is fitted with a fluorescent lamp (8 W) without a socket
outlet. It is attached using magnets which ensures a high degree
of flexibility.
The lamp is switched via a door contact and supplied via an
internal control transformer. The light is installed in the control
cabinet.
L55
Cabinet heater to protect against condensation and/or
operation with supply air temperature of -5 °C or below
L55
Cabinet heater (example shown)
With option
L55
cabinet heaters are used with 250 W per control
cabinet.
Cabinet heaters are recommended at low ambient temperatures
and high levels of humidity to prevent condensation or frost
damage. The number of cabinet heaters installed is determined
by the number of cabinet sections.
Cabinet heaters should be used above:
•
85 % air humidity. The maximum permissible air humidity in
the switchroom is 95 % (condensation is not permitted).
•
-5 °C supply air during operation. The minimum ambient
temperature for air-cooled converters is 0 °C in the switch-
room.
The heater is controlled by a thermostat built into the control
cabinet. It is supplied from the installed control voltage trans-
former or, if required, from an external control voltage supply.
Available as an ETO option:
•
Cabinet heaters with increased output for temperatures
between -5 ° and -10 °C.
•
The cabinet heater is controlled by a hygrostat.
N35
Controlled outgoing feeder for motor heater,
voltage 230 V 1 AC, max. 4 kW
This option is used when the driven motor is equipped with a
heater that is supplied from the converter. It is important to note
that the heater voltage is identical to the control voltage,
normally 230 V/50 Hz.
The outgoing feeder can be controlled internally by the
converter or externally.
The heater data (voltage/power) of the heater must be included
in the order.
N36
Controlled outgoing feeder for external motor fan –
external fan voltage for 3 AC. Converter line voltage, max. 4 kW
This option is used when the driven motor is equipped with an
external fan motor that is supplied from the converter. It is impor-
tant to note that the external fan voltage must be identical to the
line voltage.
The outgoing feeder can be controlled internally by the con-
verter or externally. The motor data (voltage/current) of the
external fan motor must be included in the order.
Y11
Undervoltage release for main switch or circuit breaker;
specify coil voltage
With option
Y11
an undervoltage release will be installed for a
main switch or circuit breaker. The voltage for this release must
be specified.
Application examples:
•
In combination with options
S01
or
S02
and the externally
backed-up control voltage of the converter, Safety Integrity
Level (SIL) 3 according to EN 61508 can be achieved.
There is no need for a second main contactor.
Disadvantage:
Automatic reset is not possible, because the main switch or
circuit breaker must be reclosed manually.
An externally backed-up control voltage is necessary.
•
With an undervoltage release, Safety Integrity Level (SIL) 1
can be achieved without a main contactor and without an
EMERGENCY OFF relay.
Disadvantage:
Automatic reset is not possible, because the main switch or
circuit breaker must be reclosed manually. An externally
backed-up control voltage is necessary.
Note:
Please specify the application case in the order.
