3.9. Monitoring and Relay Output Connections
Front Panel DB9 Connection
The front panel DB-9 connector is used to hook up a standard RS-232 cable (such as APC part number 0129-XX. A 0129-6 is included with this manual. ). This will allow local access through a Terminal Emulation program such as HyperTerminal™ or Procomm.™
RJ45 Ethernet Connector
The management card has an RJ-45 connector to support a TCP/IP protocol over a 10/100 BaseT Ethernet Local Area Network (LAN).
Major, Minor and Relay 1 Output Connections
There are three output relays available that provide outputs via Form “C” contacts. The output relays are named Minor, Major and Out Relay 1. Various system alarm conditions can be assigned to any of these three output relays. Most alarm conditions are shipped programmed to Minor or Major Relay. Wago connectors are located on the backplane card mounted in the left rear of the unit. Refer to the board layout in Figure 3.9-1 for Output Relay connections. The Wago connectors accept wires 26 AWG to 20 AWG (0.129mm2 to 0.518 mm2). To connect the relay output, remove ¼ in (6mm) of insulation from the end of the wire. Push down the white tab on the Wago connector, insert the stripped wire and release the tab to make the connection. The relay contacts should only be used to switch resistive loads of 0.5 A or less at 60 V or less.
