  • Page 6: Installing The Steca Pa15 Tts Remote Switch

    ⇒ National Electric Code including Article 690 3.2 Choosing the installation site The Steca PA15 must be connected to the battery and the consumer devices. As the line losses and therefore also the voltage drops need to be kept as low as possible, the PA15 must be installed in such a way that the cable paths selected are as short and direct as possible.

  • Page 7: Wall Installation Pa15

    The base on which the PA15 is installed must not consist of flammable material. During operation, the device will heat up due to power dissipation. For this reason, the installation site should withstand a temperature of 85°C. 3.2.1 Wall installation PA15 The PA15 must be installed on an incombustible base.

    When commissioning the device, the consumer output is always shut down first (generator off). Only once a relevant data signal is available to the PA 15 following a successful data transfer is the load activated. If the PA15 has shut off the load (generator) due to its controller position P1 and the data transferred, the load can be reactivated by reducing the shutdown thresholds.
