Input and Output Wiring Connections
Make all connections to the FEM-03 from the back of the unit. A plug-in connector from the wall plug-
type power supply, normally supplied with the unit, delivers power. If necessary, any standard AC wall
plug unit providing 13-17VAC/250mA. or 18-24VDC/250mA. may be used. A standard female plug
(2.1mm I.D. x 5.5mm O.D.) supplies AC or DC power to the FEM-03. This connector is polarity insensitive.
The factory recommends tying one of the DC COMMON terminals to earth ground, especially for DC
operation.
Make all other connections through the two rear terminal connectors. Called the “upper” and “lower”
connectors, they are removable and have ten connections each. A label on each connector shows
connection information. Refer to the Connection Diagram on page 12 for details and typical
