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 equipment carefully and locate the warranty card. Inspect the unit visually
for damage due to shipping and report all such claims immediately to the carrier
involved. Note that each unit should have the following:
- LD08 Lamp Dimmer
- Warranty Card
- Inspection Release
Verify that all items are present before proceeding and report any shortage immediately
to your supplier.
Complete the warranty card information and send it to NAT when the installation is
complete. If you fail to complete the warranty card, the warranty will be activated on
date of shipment from NAT.
2.3 Installation Procedures
2.3.1 Warnings
Do not bundle any lines from this unit with transmitter coax lines. In all installations, use
shielded cable exactly as shown and ground ONLY as indicated. Significant problems
may result from not following these guidelines.
2.3.2 Notes
The short circuit protection of the LD08 will cause an internal fusible resistor to fail
(open) if a permanently shorted lamp is connected. This will be immediately visible on
the lamp test function, but will require bench repair of the LD08 to correct. This circuit
protects the entire lamp dimmer bus from failure if a single lamp circuit should short
externally.
It is strongly recommended that the LL08 or PB08 lamps should be used for legend
annunciation, as they permit simple legend insertion, and are electrically matched to the
interconnect of the LD08.
