3. Standalone Installation
3.1 General
The standalone version can be either set on a flat surface or mounted in a
rack. The height of the unit is 1U (1.75"H), the width of the unit is slightly
less than half the available mounting width. A rack adapter kit is available for
installing either a single unit or two units side by side in the 19" rack. This
chapter provides the information required to install the standalone LDM-
144LR unit. To install the rack-mounted unit (ME447C), see
Chapter 3
.
After the installation has been completed, refer to
Chapter 4
for operating
information and system checkout to assume normal operation.
3.2 Site Preparation
The LDM-144LR is installed within 5 ft. (1.5 m) of a grounded AC outlet
and must be situated within 50 ft. (15 m) of the associated data terminal
(for the V.35 model, the unit should be even closer to the terminal).
Allow at least 36 in. (90 cm) of frontal clearance for accessibility during
operations and maintenance. Ensure at least 4 in. (10 cm) clearance at
the rear of the unit for signal lines and interface cables.
3.3 Mechanical Assembly
The LDM-144LR standalone version is designed to be placed on a table top
or bench, and is delivered in a completely assembled format. No provision
is made for bolting the LDM-144LR to the table top.
