The Allied Telesyn 9101 is shipped with a power entry module plug. The user connects power and ground to this plug, plugs it into the 9101 power entry module (PEM), then turns on office power which applies power to the plug. The user then inserts the plug into the 9101 PEM. Finally, the user inserts fuses A and B to power the unit. The following text and diagrams describe how to wire the 9100 for power and ground.
Slots for Fuse A and Fuse B are located above the plug. Notice the connections for
