Caution
These servicing instructions are for use by qualified personnel only. To reduce the risk of electrical shock, do not perform any servicing other than that
contained in the Installation and Troubleshooting Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel.
Special Symbols That Might Appear on the Equipment
This symbol indicates that dangerous voltage levels are present within the equipment. These voltages are not
insulated and may be of sufficient strength to cause serious bodily injury when touched. The symbol may also appear
on schematics.
The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important
installation, servicing, and operating instructions in the documents accompanying the equipment.
For continued protection against fire, replace all fuses only with fuses having the same electrical ratings marked at
the location of the fuse.
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the Installation Manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his/her own expense. Any changes or modifications not expressly approved by Motorola could void the
user’s authority to operate this equipment under the rules and regulations of the FCC.
Canadian Compliance
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe A respects toutes les exigences du Règlement sur le matériel brouilleur du Canada.

Section 2
Overview
The BLE*/* is a two-way capable line extender used in CATV distribution systems. The BLE*/*
is powered by the 60/90 Vac cable supply and can be configured to pass this power to additional
line extenders. Installation of the optional return path enables two-way signal flow.
The standard model BLE*/* includes an amplifier module with an integrated dc power supply,
which is normally furnished complete in the model BLE-HSG/15 housing, as shown in

BLE*/* Installation and Operation Manual
Overview 2-3
Housing
The BLE*/* is furnished in a BLE-HSG/15 aluminum housing that protects the electronics from
weather and dissipates internally generated heat.
Figure 2-3 illustrates the BLE-HSG/15 housing and provides its dimensions:

Coaxial cable connections to the housing are made using conventional 5/8 inch × 24 threads
per-inch stinger-type connectors. Four port plugs in the cover enable access to internal test
points without opening the housing.
The BLE-HSG/15 differs from the housing of the 10A BLE (model BLE-75SH and BLE-75JH)
and the JLX series of line extenders. However, you can upgrade the 10A BLE and the JLX
series of line extenders to the 15A BLE*/* using the existing housing. To upgrade from 10A to
15A, use the BLE-15A platform assembly kit (P/N 951941-006-00). The BLE-15A kit contains
15A platform assemblies. As an alternative to the kit, you can order the current BLE*/*
electronics module configured as a 10A unit (see Fig.2-2 BLE*/* Configurator, AC Current
Capability).
Two messenger clamps are located in the side of the housing (Figure 2-5) and are secured with
5/16 inch × 24 threads-per-inch stainless steel bolts. The bottom of the housing also contains two
5/16 × 24 threaded holes located on the vertical center-line separated by four inches
center-to-center. Use these holes and the bolts from the messenger clamps for pedestal and
surface-mounting installations.
BLE*/* Installation and Operation Manual
2-4 Overview
A
Gaskets
Each housing is equipped with a recessed woven-wire RF gasket and a silicone-rubber gasket to
provide a seal between the housing base and lid. These gaskets provide efficient ground
continuity, RF shielding, and weather protection. Both gaskets must be in place and in good
condition to ensure proper operation and protection of the station. The weather gasket should be
lightly coated with silicone grease each time the BLE*/* is opened. Replace this gasket if it
becomes damaged or deformed.
