Power Down
1. Set the TXU PWR switch to 0 (off).
2. If the TXU is powered from the optional ACU, set the
ACU power switch to 0 (off).
If the TXU is powered from a source other than an
ACU, turn that power source off.
3.3.6 TXU and TCU Power Up and Power Down -
Co-Located
If your STRATA TX System consists of a co-located TXU and a
TCU, it is recommended that both the TCU and TXU be powered
from the same DC power supply in lieu of using superimposed
DC power on the coaxial cable between the TCU and the TXU.
Note
The following procedure reflects use of a single DC
power source for both the TXU and TCU in lieu of
using superimposed DC power on the coaxial
cable between the TCU and the TXU.
Perform the following steps to power up or power down a co-
located TX System:
STRATA TX

CAUTION
To avoid possible damage, turn off DC
Power on the coax before connecting any
test equipment.
Power Up
1. Verify the power cable is properly connected to the
TCU rear panel POWER connector.
2. Verify the power cable is properly connected to the
TXU front panel POWER connector.
Note If your TCU does not have a DC ON COAX
switch, go to step 4.
3. Turn the recessed DC ON COAX switch on the front
panel of the TCU until the screw slot of the switch
points to OFF.
4. Turn the recessed DC ON COAX switch on the front
panel of the TXU until the screw slot of the switch
points to OFF.
5. Verify all coaxial cables and connectors have been
properly connected.
6. Connect the TCU and TXU to DC power of the correct
voltage and polarity.
If you are unsure of the power requirements or the
connections, refer to the “Installation” Chapter on
page 6-1 (Part of the STRATA TX System Technical
Reference Manual only).
