Before connecting to an AC outlet or external power source, verify that the AC power cord, including

the extension line, is compatible with the rated voltage/current and that there is sufficient circuit

capacity for the power source. Once verified, connect the cable firmly.

The included AC power cord is safety certified for this

third conductor. Verify that your power outlet is of the

three-conductor type with the correct pin connected

to earth ground.
