2.The unit has been on utility power for more than 12 hours.

3.Temperature is between 0 and 50°C.

Output Power and Communication Signals

The PowerShield communication signals are isolated from its internal circuitry via open collector opto-coupled transistors. The connection labeled “Signal Return” is a common return point for all communication signals. In the typical application, the attached equipment digital ground connects to Signal Return, and pull-up resistors turn the open collector signals into logic levels.
