Precis LT Instruction Manual
To install and set up a Precis LT system in a rack:
1.
On the side of the Precis LT, remove the bottom two screws closest to the front panel (FIG. 5).
Align the holes on one of the rack ears with the empty holes on the side of the enclosure and replace
the screws (three screws for the 1 RU; four screws for the 2 RU).
Repeat for the other rack ear.
2. Place the enclosure in the rack and attach front-mounting screws to hold it firmly in place.
Tip: When placing enclosures, keep in mind that the optimal viewing angle for a control panel is eye
level.
3. Attach only the first two source devices and the first two destination devices; see “Attaching Inputs
& Outputs” on page 20.
Do not apply power to the devices until after the Precis LT has power (Step 5).
4. Optional – Establish communication with an external control device/system; see “Attaching an
External Controller” on page 17.
5. Apply power to the system according to the power-up procedure; see “Applying Power & Startup”
on page 26.
Note: We recommend using surge protectors and/or AC line conditioners.
6. Execute a test switch to ensure the system is working properly; see “Executing a Test Switch” on
page 28.
7. When the test switch works correctly, attach the remaining source and destination devices.
