3.9. Monitoring and Relay Output Connections

Front Panel DB9 Connection

The front panel DB-9 connector is used to hook up a standard serial cable for the APC proprietary GUI that will be introduced at a later date. Do not hook up the special RS-232 cable (APC part number 940-0024C). This cable is only to be used with the DB-9 near the Web/SNMP card.

“Smart” Cable DB9 Connection

The DB9 connector on the top right hand side of the unit uses the special RS-232 cable (APC part number 940-0024C) to allow local access through a Terminal Emulation program like HyperTerminal™ or Procomm™ (**).

RJ45 Ethernet Connector

The optional management card has an RJ-45 connector to support a TCP/IP protocol over a 10BaseT Ethernet Local Area Network (LAN).

Relay Output Connections

There are eight alarms available that provide outputs via Form “C” relay contacts. The last two of these are preassigned as the Minor and Major relay outputs. The Major relay is energized (NO-C contacts closed) during normal (non-alarm) operating conditions; all the other relays energize when an alarm condition occurs. The other six outputs are initially designated as “Relay 1” through “Relay 6” (the user may assign more meaningful names if desired). The various system alarm conditions can be assigned to any of the eight alarm outputs. Connectors J1 and J2 are located on the interface card mounted in the top left side of the unit. Refer to the board layout in Figure 3.8-3for Output Relay connections. The relay contacts should only be used to switch resistive loads of 0.5 amperes or less at 60 volts or less. The following shows the alarm output connection designations.
