Introduction

Thank you for selecting an EATON product to protect your equipment.

The EX RT range has been designed with the utmost care.

We recommend that you take the time to read this manual to take full advantage of the many features of
your UPS.

Warning: this is a class A UPS product. In a domestic environment, this product may cause radio
interference, in which case, the user may be required to take additional measures.
If the device must be installed in overvoltage category III or IV environments, additional upstream
overvoltage protection must be provided for.

To discover the entire range of EATON products and the options available for the EX RT range,
we invite you to visit our web site at www.eaton.com or contact your EATON representative.

Environmental protection
EATON cares about the environmental impact of its products and has therefore implemented an eco-design
process for the entire life cycle of the EX RT product: design, usage and recycling.

2.4 Communication ports

EX RT provides 3 communication methods that can be used simultaneously:
zz The COM port provides RS232 communications using EATON SHUT protocol. Compatible with most
power management software applications available into the enclosed Solution Pac CD-Rom.
zz The output contact port is used for basic signaling or for protection of IT systems like IBM iSeries
(formerly AS400) and more.
zz The slot is compatible with any EATON communication card (check www.eaton.com web site for the
complete list of compatible cards).

Connection to the RS232 communication port

1 - Connect the RS 232 23

communications cable to the serial
port on the computer.
23
2 - Connect the other end of the
communications cable 23 to the RS
232 5 communications port on the
UPS.

The UPS can now communicate with
various EATON power management
application software. Please note
that the configuration software is
included with Personal Solution Pac
for Windows.

Remote Power Off

Installation of a Remote power off function must be carried out in compliance with applicable regulations.

In order to fully de-energize devices and EX RT with an RPO port, it is necessary :

- To use a two-position switch (Normally Open or Closed contact should be held more than 1 second to be
taken into account).
- To use battery cabinet(s) EX RT EXB EPO.
- To connect to this RPO switch a device that allows to trip all breaker(s) located upstream(1) AC NORMAL
and AC BY PASS as well as downstream(2) the EX RT. This can be achieved through by means of a shunt
trip.

(1) If not, the output devices will remain powered through the AC BY PASS if RPO switch has been
loosened.
(2) If not, the output devices will remain powered several seconds after the RPO activation.

Remote Power Off communication port 3

Used in conjunction with the optional EPO battery module, this port enables total isolation of all power
sources connected to the UPS in case of emergency (the cable is not provided).

zz This type of connection must be carried out by qualified electrical personnel.
zz Before carrying out any connection, check that the battery circuit breaker 12 and that the upstream
protection devices (Normal and Bypass AC sources) are open ("0").
zz EX RT UPS always comes from factory with Normal and Bypass AC inputs already connected together,
using a bridge.
zz Use included insulated ferrules with stranded wires.

zz Battery backup time is adversely affected by high and low temperatures. It is significantly reduced at
temperatures under 10°C. Above 25°C, battery service life is cut in half every 10°C. Above 40°C, battery
manufacturers no longer guarantee operation due to the risk of thermal runaway.

5.2 Glossary
Backup time Time that the connected loads can operate on battery power.

Bypass AC source Source supplying the bypass line. The load can be transferred to the bypass line if
an overload occurs on the UPS output, for maintenance or in the event of a
malfunction.

ECO mode Operating mode by which the load is supplied directly by the AC source if it is
within the tolerances defined by the user. This mode reduces the consumption of
electrical power.

Load Devices or systems connected to the UPS output.

Manual bypass Rotary switch controlled by the user, used to connect the loads directly to the
AC source.
Transfer of the load to the manual bypass enables UPS maintenance without
interrupting the supply of power to the connected loads.

Normal (double conversion) mode

The normal UPS operating mode in which the AC source supplies the UPS which
in turn supplies the connected loads (after electronic double conversion).

Normal AC source Normal source of power for the UPS.

Relay contacts Contacts supplying information to the user in the form of signals.

UPS Uninterruptible Power Supply.
