CAUTIONS:

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 circuit.

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.
