  • Page 9 Figure. 3 - 1. Arc protection device AQ-103LV. The AQ-103LV is designed according to the latest protection relay standards and it is therefore suitable for installations in rough environments. These include utilities and power plants (both traditional and renewable), various heavy industry applications (oil, gas, mining, steel, etc.) as well as commercial and...
  • Page 10 4 Device features AQ-103LV is an arc flash protection device which can be applied to a variety of applications. It can be used on its own as a stand-alone device, or it can be a part of a more complex arc protection system by using binary inputs and outputs to connect multiple AQ 100 series devices together.

  • Page 19: Arc Light Fiber Optic Loop Sensor Aq-08

    If necessary, the ends of an AQ-07 cable can be ordered with heat shrinking tubing to avoid light detection outside the protected zone. The covered area can be one (1) or two (2) meters by default; if other lengths are required, please consult the Arcteq sales team. You can find the Contact and reference information page at the end of this manual.

    2. Install protective covers in the holes to ensure the sensor cable remains unharmed by rough edges. 3. Run the sensor cable through the holes and along the protected area. Fasten it to the compartment walls with cable clips or some other appropriate anchoring method. © Arcteq Relays Ltd IM00045...

    AQ-103 and AQ-103LV can be ordered with Modbus RTU serial communication to report various signals to external devices. It is mainly designed for connecting to AQ-S254 but any Modbus master can be used. Up to 16 AQ-103 or AQ-103LV devices can be connected to one system. Modbus polling rate The recommended maximum polling rate for the Modbus protocol is twice per second (2/s).
