4.1. Connecting Power to the APS Unit

The APS-8/16M is available in both AC and DC powered versions. When connecting power, proceed as follows:

CAUTION:

•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.

4.1.1.AC Powered Units

Plug the power cable (supplied with the unit) into the receptacle on the back panel, and then connect the power cable to an appropriate, grounded outlet. The APS features a self adjusting power supply that automatically adapts to power supplies between 100 and 240 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

The DC terminal block features two bus inputs as shown in Figure 4.1. This allows the user to connect only one DC power source, or connect two DC power sources where the second source serves as a backup. When connecting the APS-8/16M to your DC power source, ﬁrst remove the protective cover from the terminal block, attach the wires from the -48V DC power source to the screw terminals, connect your ground line to the labeled ground screw, and then replace the protective cover.
