The Standard OM20 is shipped in a single box that contains mating connectors. Carefully unpack
the unit and ensure that all of the above items are in the carton. The standard OM20 power supply
is designed for universal AC (95-250VAC, 50/60 Hz) application and is capable of supplying DC
power to the BUC and LNB. See the specification section of this document for appropriate
voltages and currents. Optionally, a -48VDC power supply may be specified for the unit.
CAUTION
Always ensure that power is removed from the OM20 before removing or
installing the BUC or LNB. Failure to do so may cause damage to the
equipment.
