Section 2.0 Installation
2.1 Introduction
Information in this section consists of unpacking and inspection procedures, installation
procedures, post-installation checks, and installation drawings.
2.2 Unpacking and Inspection
Unpack the unit and inspect visually for damage due to shipping and report all such
claims immediately to the carrier involved. Note that each unit should have the
following:
- LL08 Legend Lamp
- Two transparent ‘Legend’ sheets
- Installation Manual
Verify that all items are present before proceeding and report any shortage immediately
to your supplier.
2.3 Installation Procedures
2.3.1 Cautions
The lens assembly fits in the housing with either colour to the right, so to ensure correct
wiring follow the drawings in Section 2.5.
2.3.2 Notes
Other lens combinations are available from NAT, or they can be interchanged with
legends from the PB08.
2.3.3 Installing the Legends
To install the required legends into the LL08, first examine the legends supplied, and
pick out the combination that is most suitable for your application. Note that both
horizontal and vertical legends are provided. If used for warning/alert indications, the
RED legend is warning, and the AMBER legend is alert.
Cut the legends along the border line and then into two individual sections using a pair of
sharp scissors. Withdraw the lens/diffuser assembly from the switch body by gripping the
lens cap on the provided notches and pulling out. A slight rocking motion will make it
easier. Pop the lenses off the diffuser and insert the legends of your choice, making sure
they are adequately trimmed and square. Replace the lenses, then push the whole
assembly back into the switch body. When it is firmly seated, it will lock into place.

2.3.4 Changing Lamps
To replace or change lamps, withdraw the lens/diffuser assembly and pull out the lamp
with a pair of needle-nosed pliers. Push in a new lamp and press down on the top of
the lamp with the end of a pencil eraser or other object until the lamp clicks into place.
When it is correctly seated, it will not move farther in. Replace the lens assembly.
