Power Connection for U.S. Application
Connect the TFP 010 power supply to the 3-pin Molex™ connector located on the rear of the TX90 (see Figure 7).
For Applications Outside the U.S. Requiring 240 VAC Mains Supply:
Use the transformer power supply, model TFP 027. Make sure TFP 027 power input switch (located on bottom of power supply) is
set to the “230” position. Secondary specications: 24 VAC, 35 VA, 50/60 Hz.

TFP 027-02: 230VAC, UK Mains Plug
NOTE: The WIR TX90 transmits when a baseband signal is present, and will shut off immediately when no baseband signal is
present. This auto shut-off feature preserves the life of the infrared LEDs and reduces power consumption.
This system is designed for class 2, low-voltage wiring. Always follow local electrical codes when doing low voltage wiring.
