When writing signal names on the label by hand

1. Use the pre-printed transparency.

2. Write the names on the transparency with permanent pen or by typewriter.

3. Put the label in the pocket on the front panel of REX 521.

When writing signal names on the label by using computer

1. Select a template for the label. The templates can be found in Technical

Descriptions of Functions CD-ROM (see “Related documents” on page 10) and

in the Internet address www.abb.com/substationautomation (under Shortcuts,

select the option REX 521 from the Distribution products list box).

• Excel-format template (Label1MRS151301.xls) can be used when you want to

save the signal names for example on the hard disk of your PC.

• Pdf-format template (Label1MRS151300.pdf) can be used when you use

Acrobat Reader and only want to print the signal names on the label.

2. Depending on printer, the print size may vary: test print the label on paper

before printing it on transparency. To adjust the print height to the maximum

height of the label (106 mm), use the zoom option of the printer settings.

3. Print the label on the blank transparency. It is recommended to write and print

two labels at the same time since the templates contain two labels to fill the

signal names in.

4. Put the label in the pocket on the front panel of REX 521.

Use only laser printers for printing. Ink jet printers are not suitable

for printing on label transparencies.
