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 specifications: 24 VAC, 35 VA, 50/60 Hz.

Plug the power supply into the AC outlet.

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.
