Chapter 1 Introduction
The Eaton®Powerware®Modbus®Card is an X-Slot®connectivity device
that allows you to continuously and reliably monitor the UPSs in your
Building Management System (BMS). The card uses the Modbus
protocol to integrate data from the UPS into your building management
software, such as Wonderware
The Modbus Card, shown in Figure 1, has the following features:
S RS-485 communication through an isolated DB-9 port or isolated
terminal strip
S Selectable termination and polarity resistance
S RS-232 communication through a DB-9 port
S Supports Modbus READ INPUT STATUS and READ INPUT REGISTER
commands
S Two-wire or four-wire communication topology
S LEDs showing communication activity
S The Modbus Profiler tool can generate a Modbus register map for
easy integration into your building management software (see
page 17)

Chapter 2 Installing the Modbus Card
The Modbus Card is available:
S as a separate card for use with UPSs that have an X-Slot
S factory-installed in a Powerware Expansion Chassis
Use the following sequence for installing the Modbus Card:
1. For four-wire networks only, change the jumpers on the Modbus
Card (see “Four-Wire Communication” on page 4).
2. If the Modbus Card will be the last device installed in the network
chain or the length of the network cable is excessive, termination
needs to be enabled (see “Termination” on page 10).
3. Install the card with the UPS (see the Powerware Expansion
Chassis User’s Guide or “Installing the Modbus Card into an X-Slot”
on page 6).
4. Wire the card to your network (see Chapter 3, “Wiring the Modbus
Card”onpage7).
5. Configure the card (see Chapter 4, “Modbus Card Configuration”
on page 13).
6. Run the Modbus Profiler tool to integrate the UPS data with the
building management software (see Chapter 5, “Integrating the
UPS” on page 17).
Inspecting the Equipment
If any equipment has been damaged during shipment, keep the shipping
cartons and packing materials for the carrier or place of purchase and file
a claim for shipping damage. If you discover damage after acceptance,
file a claim for concealed damage.
To file a claim for shipping damage or concealed damage: 1) File with
the carrier within 15 days of receipt of the equipment; 2) Send a copy of
the damage claim within 15 days to your service representative.

INSTALLING THE MODBUS CARD
Four-Wire Communication
The factory-default setting for the Modbus Card is for two-wire
communication. To change the default setting, adjust the jumpers on the
Modbus Card.
To prevent electrostatic discharge (ESD), place one hand on an unpainted metal surface such
as the UPS rear panel.
1. If you are installing the Modbus Card into an X-Slot, complete
Step 3 only.
If you are installing the Powerware Expansion Chassis with your
UPS, complete Steps 2 through 4.
2. Remove the card from the slot on the Powerware Expansion
Chassis rear panel. Retain the screws (see Figure 3).

INSTALLING THE MODBUS CARD
Installing the Modbus Card into an X-Slot
To prevent electrostatic discharge (ESD), place one hand on an unpainted metal surface such
as the UPS rear panel.
1. Remove the X-Slot cover (or existing X-Slot module) on the UPS
rear panel. Retain the screws (see Figure 5).
NOTE Some UPSs may have another X-Slot module already installed (such as the
Powerware 9125 UPS). If there is a communication cable attached to this module, disconnect
the cable and then remove the X-Slot module.
CAUTION
Figure 5. Removing the Single-Port Module
2. Install the Modbus Card into the X-Slot on the UPS.
Align the Modbus Card with the slot guides and slide the card into
the slot until it is firmly seated.
Secure the Modbus Card with the screws removed in Step 1.
