is possible by DB-9 cable on the Console Port of the module and via RJ-45 (Ethernet) cable on the 10/100 Base-T port on the Network Management Card.

“Smart” Cable DB9 Connection

The DB9 connector on the top left 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™ (**). This port is labeled as “Console”.

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).

CAUTION: The Web/SNMP card has a lithium battery. This battery is not field serviceable.

Danger of explosion if battery is replaced by an incorrect type.

Dispose of used batteries according to the manufacturer’s instructions

Relay Output Connections

There are eight relays available that provide outputs via Form “C” relay contacts. The last two of these are pre-assigned as the Minor and Major relay outputs. The Major relay is energized (N/O-COM 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”. Any of the various system alarm conditions can be assigned to any of the eight relay outputs. Wago connectors are located on the customer interface card mounted in the top right side of the unit. The relay contacts should only be used to switch resistive loads of 0.5 A or less at 60 Vdc or less. Table 3.10-1 shows the alarm output connection designations.
