Aparato de vigilancia del aislamiento
Uso correcto del aparato
El ISOMETER® IR425 vigila la resistencia de aislamiento R
F
de cir-
cuitos de corriente de mando AC aislados de tierra (Sistema IT) de
AC 0…300 V y DC 0…300 V.
La capacidad de desviación tolerada C
e
max es de 20 µF.
Observaciones sobre seguridad en general
Además de este manual constituyen parte integrante de la docu-
mentación de aparatos las “Instrucciones de seguridad para pro-
ductos Bender”, que se adjuntan.
Indicaciones sobre seguridad específicas para
el aparato
Solo deben realizar la instalación, puesta en mar-
cha o conexión del sistema personas
debidamente cualificadas.
Riesgo de electrocución!
El contacto con las partes activas de la instalación
puenden conllevar:
• Electrocución
• Daños en la instalación eléctrica
• Destrucción del equipo
Antes de instalar y conectar el equipo verificar
que la instalación se encuentra sin tensión. Veri-
fique las normativas para trabajar en sistemas ba-
jo tensión.
¡Peligro de daños materiales por instalación
incorrecta!
La instalación podría resultar dañada, si se conec-
ta más de un aparato de vigilancia de aislamiento
a un sistema conectado conductor de tensión. Si
se han conectado varios aparatos, el aparato no
funcionará y ya no emitirá avisos en caso de fallo
de aislamiento. Conecte solamente un aparato de
vigilancia de aislamiento por cada sistema con-
ductor de tensión.
¡Observar la separación del sistema IT!
Antes de realizar pruebas de aislamiento y de ten-
sión en la instalación, el aparato de vigilancia de
aislamiento debe separarse del sistema IT durante
todo el tiempo que dure la prueba. En caso contra-
rio el aparato podría resultar dañado.
En caso de mensaje de alarma, el fallo de aisla-
miento se debe reparar lo antes posible.
Si el ISOMETER® es instalado dentro de un cuadro
eléctrico, el aviso de fallo de aislamiento debe ser
audible y/o visible para llamar la atención.

CUIDADO
Insulation monitoring device
Intended use
The IR425 ISOMETER® monitors the insulation resistance of an
unearthed AC or DC control circuit (IT system) of AC 0…300V
respectively DC 0…300 V. The maximum permissible system
leakage capacitance C
e
is 20 µF.
Safety instructions
Part of the device documentation in addition to this manual is the
enclosed "Safety instructions for Bender products".
Device-specific safety information
Only qualified personnel are permitted to carry
out the work necessary to install, commission and
run a device or system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device,
make sure that the installation has been de-en-
ergised. Observe the rules for working on electri-
cal installations.
Risk of property damage due to unprofession-
al installation!
If more than one insulation monitoring device is
connected to a conductively connected system,
the system can be damaged. If several devices are
connected, the device does not function and does
not signal insulation faults. Make sure that only
one insulation monitoring device is connected in
each conductively connected system.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried
out, the device shall be isolated from the system
for the test period. Otherwise the device may be
damaged.
In the event of an alarm message, the insulation
fault should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabi-
net, the insulation fault message must be audible
and/or visible to attract attention.
