power supply specifications on the product label and the following
information.
Observe proper ESD techniques when connecting and disconnecting the
DeviceMaster.

Insert the DC positive wire into one of the + screw terminals and the DC
return wire into the - screw terminal.
A second redundant power supply can be connected to the unit by inserting
the DC positive wire into the other + screw terminal and the DC return
