Wiring

Do not connect the power signal wiring to the test terminals. Voltage may burn out the
reverse-polarity protection diode in the test connection.
Note
Use shielded twisted pairs to yield best results. To ensure proper communication, use 24 AWG
or larger wire, and do not exceed 5000 feet (1500 meters).
