4.0 OPTIONS
Several items of optional equipment are available for connection to the NX UPS.
4.1 Communication and Other User Terminals
The UPS can be integrated into advanced networking environments via UPS monitoring software
such as Windows-based UPS Monitor, HiroLink + HiroVisor, SiteNet, Modbus / Jbus, SiteScan,
SiteScan 2, SNMP, etc. They allow UPS status monitoring and automatic and safe shutdown of the
server and PCs.
With an optional modem card installed, the UPS can dial out to pagers and telephone numbers under
selected or pre-defined alarm conditions.
4.1.1 External Battery Temperature Detect Interface
A connector at the X7 slot permits installing an optional TMP12Z temperature detector for external
batteries. (A temperature detector is installed for the NX’s internal batteries.)
4.1.2 Analog Input Interface
At the X6 slot, there are two analog signal channels. Input range is from 0 to +5V, and the precision is
2%. “ENV-T” is used for environment temperature detecting.
4.1.3 Power Output
The X5 slot can provide power for a modem or an external SNMP card. Available voltage is from 9V to
12V. The maximum current is 500mA.
4.1.4 RS232 Interface
There are two RS232 interface at the monitor board: “BACKGROUND 232-1” and “BACKGROUND
232-2”.
“BACKGROUND 232-1” can be connected to Modem for remote monitor. 232-1 and 485_1 share the
same one serial communication resource (SCI 1), they can not be connect to monitor device at the
same time.
“BACKGROUND 232-2” can not be connected to Modem. It shares the same one serial communication
resource (SCI 2) with Intellislot 2. They can not be connected to monitor device at the same time.
4.1.5 RS485 Interface
There are two RS485 interface at the X4 slot: 485_1 and 485_2. 485_1 can be used only when the UPS
is in “Multipoint to point” mode. The two parallel UPS modules’ 485_1 can be connected together to
background. 485_1 and 232-1 share the same one serial communication resource (SCI 1), they can not
be connected to monitor device at the same time. If not on “parallel monitor mode”, 485_1 is disabled.
485_2 shares the same one serial communication resource (SCI 3) with Intellislot 3. They can not be
connected to monitor device at the same time.
4.1.6 Intellislot™
The NX UPS contains three Intellislot communication slots to allow the operator to field install
optional communication cards. Each bus can independently communicate via Liebert ESP2 protocol,
and cards that translate the information on the bus to the specific protocol needed: Modbus / Jbus,
SNMP, IGMnet and serial port card. But Intellislot 1 and RS232 use one common bus; only one of
them can be used at the same time. The Intellislot communication slots are designed to provide sim-
ple installation where all electrical connections are made via a 34 pin edge card connector. These
option cards allow the UPS to communicate via multiple communication methods to monitoring appli-
cation interfaces.

CAUTION
To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables should
be segregated and run separate from all other power cables, by 25mm where applicable.
