RS-232 interface
The mains input interface on the device is a 3-pin standard cold appliance socket
connection, which is integrated into the mains input module. Connection to the mains
is effected via a 3-pin power cord with a non-fused earth conductor.
The mains input is a wide range input from 95Vac ... 240Vac. The mains input
module contains the two primary fuses.
