External voltage sense connections are at the programmed output voltage when the
output is on so DO NOT connect or disconnect the external voltage sense lines while the AC
power source is in use.
AFX L Version units are shipped with the mating sense connector installed but no wires to
prevent contact with the sense connections. AFX A Version units don’t require a mating
connector.
