Use the supplied consecutive numbers to label terminals in sequence. For replacement, remove the old marker by pulling it out of the holder and insert the new marker strip in the same orientation.

Usage recommendations

For durable identification, install markers on clean, dry surfaces and ensure they are fully seated in the marker holders. Use the 5 mm markers for narrow terminal rows and switch to wider markers where more visible or larger text is required. Keep spare strips from the same set for consistent numbering during future maintenance.
