4.1. Connecting Power to the RSM Unit
The RSM is available in both AC and DC powered versions. When connecting
AC or DC power to the RSM, proceed as follows:
• Before attempting to install this unit, please review the warnings
and cautions listed at the front of the user's guide.
• This device should only be operated with the type of power
source indicated on the instrument nameplate. If you are not
sure of the type of power service available, please contact your
local power company.
• Reliable earthing (grounding) of this unit must be maintained.
Particular attention should be given to supply connections when
connecting to power strips, rather than directly to the branch
4.1.1. AC Powered Units
Plug the power cable (supplied with the unit) into the receptacle on the RSM
back panel. Then, connect the power cable to an appropriate, grounded outlet.
The RSM features a self adjusting power supply that automatically adapts to
power supplies between 90 and 250 VAC. Press the Power Switch ON. The
ON LED should light and the RDY LED should begin to ﬂash.
4.1.2. DC Powered Units
When connecting the RSM to your DC Power source, ﬁrst remove the
protective cover from the terminal block, attach the wires from the -48 VDC
power source to the screw terminals, connect the ground line to the labeled
ground screw, and then replace the protective cover.
