  • Page 19: Connecting Transformer Taps/Load Wiring

    It is important to choose the correct tap based on the loaded line-to-line voltage (i.e., the line voltage present when the NX100 is operating at full power and full modulation) for maximum peak modulation capability and maximum efficiency. If the loaded line-to-line voltage falls between two tap settings, choose the higher voltage tap (this will maximize the NX100‘s power factor).

    Nautel may provide an EMERGENCY STOP switch. Close the ac power disconnect switch’s front door. 5. Route the load wiring from the ac power disconnect switch to the transformer cabinet, passing all the conductors, as a group, through a ferrite toroid (Nautel Part # LX63, provided in the ancillary kit).. Note: The preferred entry point for ac input wiring is through a hole in the primary side of the transformer cabinet.
  • Page 28 NX100 Installation Manual Connecting ac power 8. Connect the ac line input to the H1 (Line 1), H2 (Line 2) and H3 (Line 3) input terminals on the transformer (see Figure 4.1 on page 4-2). Connect the ac ground to the transformer’s ground stud.

  • Page 29: Adjusting The Spark Gap

    Section 6: Adjusting the spark gap The NX100’s RF output filter contains a spark gap that must be adjusted - based on site altitude - to provide protection against excessive voltage (i.e., lightning) on the RF output. If the altitude of the transmitter site is known prior to transmitter delivery, then the spark gap is adjusted at Nautel.
