Precis LT Instruction Manual
Applying Power & Startup
The enclosure’s universal power receptacle will accept all major international standard power sources.
Standard US power cords are provided for installations within the US. Maximum power specifications
are on the power receptacle (also listed on page 11). Always use an earth-grounded power cord / system
with a Precis LT.
The source electrical outlet should be installed near the Precis LT, easily accessible, and properly
grounded. Power should come from a building branch circuit. We strongly recommend using a dedicated
line for the system’s power. Use a minimum breaker current rating of 15 A for 110 V or 30 A for 230 V.
To avoid an overload, note the power consumption rating of all the equipment connected to the circuit
breaker before applying power.
Caution: To avoid system damage, turn on the power switch for the AMX AutoPatch equipment
before
applying power to the system’s source and destination devices. We recommend attaching all
power cords to a surge protector and/or an AC line conditioner.
Power-Up Sequence
To apply power:
1.
Attach the first two source and destination devices (see “Attaching Inputs & Outputs” on page 20).
Do not apply power to the source and destination devices until Step 7.
2. If applicable – Attach an external controller (see “Attaching an External Controller” on page 17).
3. Plug one end of the power cord into a power strip that is turned off (we recommend using a 30 A
power strip).
4. Plug the power cord into the power receptacle on the enclosure.
Press the “I” side of the enclosure’s power switch.
5. Turn on the power strip.
The Power Indicator on the front of the enclosure illuminates (FIG. 22).
6. If applicable– Apply power to the external control device/system.
7. Apply power to the source and destination devices.
For startup information on specific types of control before executing a test switch, see page 17.
The system is ready for a test switch (see “Executing A Test Switch” on page 28).
