6. Software and connectivity

The software Suite CD-ROM that is bundled with the UPS contains software distributions and

documentation in CD format. Furthermore, the comprehensive connectivity option portfolio

includes Web/SNMP adapters for networked environments, Modem card for 24/7 remote

monitoring, ModBus/Jbus card for building management system integration, relay interface

cards for industrial and facilities use and RS-232 cards for serial communication to one or

multiple computers.

Communication cables

It is recommended that the control cables and power cables be installed on separate trays.

Where control cables will cross power cables make sure they are arranged at an angle as near

to 90 degrees as possible.

All control cables shall preferably be shielded. If the shield is grounded, this shall take place on

only one end of the cable.

The procedure for connecting the control cables is the following:

1. Remove the front cover by lifting the cover from the bottom outwards by releasing the

retaining clip. It’s located in the bottom part of the bezel.

2. Locate the control terminal or XSlot module where you want to install the communications

cable.

RS-232 (X53); Relay output (X57).

Connection to the standard RS-232 port (X53)

The standard RS-232 interface uses 9-pin female D-sub connector. It shall be used with the

delivered cable for a computer or external modem connection. The data is transmitted with XCP

protocol that includes status and meters information about the UPS. The RS-232 port has the

following format:

• Communication speed 19200 bps*

• Data bits 8

• Parity None

• Stop bits 1

• Handshake None

* Communication speed can be changed via LCD menu

LanSafe software

The LanSafe software shuts down computers and whole networks in case of an extended power

failure. It provides basic monitoring, data logging, notiﬁcation and event actions for a single

UPS solution. The software is bundled free of charge in Software Suite CD.

The connection procedure for the RS-232 interface port is following:

1. Connect the RS-232 communication cable to the computer.

2. Connect the RS-232 communication cable to the serial interface on the UPS.

3. Run the UPS software installation disk (Software Suite CD) on the computer.

Note!

If communication does not work choose the correct baud rate from the LCD menu

Please refer to the optional software manuals for appropriate bit rate

settings.

External control connections

The UPS has an input/output interface for direct communication with your computer system.

It is located behind the front bezel of the UPS unit. The cables connected to these terminals

should be connected to cable clips.

Input and output terminals have a functional isolation from terminal to terminal. They are

connected to the chassis through individual 1 M resistors.

Figure 28. External control cable connections to the UPS.

Note!

Pay attention to proper polarity if one is using a semiconductor switch type. A relay

or other mechanical control is a preferred method.

Emergency Power Off (EPO)

This input is used to shut down the UPS from a distance. This feature can be used for

emergency power down. There are two modes of operation, normally closed at X52 and

normally open at X12. Remote shut down terminal X52 pins 1 and 2 are as factory default linked

(X12 is open). When the loop on X52 is opened, the logic circuitry will immediately shut down

the UPS output and open the battery breaker (F1).

Note!

EPO does not necessarily disconnect supply to load when unit is on internal or

external bypass. Quaranteed disconnection of bypass supply has to be through a

separate disconnect switch located in the supplying switchgear cabinet.

In order to have the UPS running again pins 1 and 2 of connector X52 have to be reconnected and

the UPS started manually. The pins must be shorted in order to keep the UPS running. Maximum

resistance is 10 ohm. The EPO shall not be galvanically connected to any mains connected circuits.

Reinforced insulation to the mains is required. See also “Start-up after EPO”.

If the use of normally open EPO operation is desired, the loop on X52 has to be retained and the

normally open EPO switch connected to X12. Operation is as above.

Relay outputs

The UPS incorporates a programmable relay output with potential free contacts at X57 for remote

alarm indications. It is rated for max. 30 VAC 1 A or 60 VDC 0,2 A nominal values. Additional (4)

relay outputs can be obtained with the XSlot compatible AS/400 Relay Module (optional). For

more information see the section “Using relay outputs”
