Sicurezza
Use of the device outside the Federal Republic of Germany is subject to the standards and regulations applicable at the place of use. In Europe, EN 50110 applies.
Pericolo! Risk of death 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-energised. Observe the rules for working on electrical installations.
Uso previsto
The AGH520S is used to connect the ISOMETER®s iso685, IRDH275 or IRDH375 to AC systems up to 7.2 kV in online mode. Alternatively, the AGH520S can be used in combination for 7.2 kV AC systems in offline mode. The coupling device is only to be used in combination with the ISOMETER®. Any use other than that described in this manual is regarded as improper.
Device-specific safety information
Danger of electric shock! The coupling device is operated with voltages up to 7.2 kV. Wrong connection can lead to death, severe bodily injury, or substantial damage to property. Only electrically skilled persons are allowed to work on or with the device! Before working on the coupling device, ensure that the operating area is disconnected from the power supply! Please observe the following installation instructions.
Descrizione funzionale
The coupling device AGH520S is used to extend the nominal voltage rangeof the ISOMETER® illustrated in the wiring diagram to 3(N)AC 50…400 Hz, 0…7.2 kV. For details, refer to the wiring diagram.
Installazione e collegamento
- Danger of electric shock! The coupling device is connected to the protective conductor via the earthing terminals of the connected ISOMETER®. All PE connections of the ISOMETER® must be connected to the protective conductor to ensure safe operation.
- Risk of damage to property, injury, and fire! Please check for the correct system voltage e fornitura voltage. Ensure short-circuit-proof and earth-fault-proof wiring.
- If the coupling device is coneccted to a live system, the terminal AK or AK160 must not be disconnected from the ISOMETER®.
- DIN EN 45545-2:2016: Application in railway vehicles. If the horizontal or vertical distance to adjacent components which do not meet the requirements in table 2 of DIN EN 45545-2 is less than 20 mm (horizontal) or less than 200 mm (vertical), respectively, they are to be regarded as grouped. Refer to DIN EN 45545-2 chapter 4.3 Grouping rules.
