This instrument operates from a single-phase power source with one current-car-
rying conductor at or near earth-ground (the neutral conductor). Only the line
conductor is fused for over-current protection. The mains frequency is 50 or
60 Hz. The operating voltage range is continuous from 100 to 240 VAC.
Note that the instrument does not have a power-switch. When you connect the
power cable to the AC voltage line, the instrument powers on.
The two Parallel Input connectors accept signals which comply with the
SMPTE 260M/274M/296M standard:

The Serial Out 1/2 connector outputs two identical converted serial digital signals
which comply with the SMPTE 292M standard.
Inspection and cleaning are preventive maintenance procedures. When done
regularly, preventive maintenance may prevent converter malfunction and
enhance reliability.
