Where MED type approved installations are required, the SF-3050 must be
powered by the supplied AC/DC power adapter, or an approved DC to DC
power converter.
This equipment is required to pass the conducted MED type emission criteria:

Unterminated DC power cable with filter (P/N 94-310274-3010LF); supplied
only with later SF-3050 production units.

Approved DC to DC power converter. The converter isolates the SF-3050
power and chassis grounds.

Replacement AC power cords are available through small appliance
retailers (Radio Shack, Walmart, Best Buy, etc.). AC power cords for non-
110VAC locales must be purchased locally.
