Overview Configuration The SLE*-* is fully configured by Motorola per customer request. It is recommended that you verify the configuration listed on the outside of the shipping carton with the configuration you ordered. The shipped configuration is also noted on labels located on the side of the housing.
For strand mounting, use the two messenger clamps located on the side of the housing (Figure 2-5) that are secured with 5/16 inch × 24 threads-per-inch stainless steel bolts. Use the “L” bracket feature for pedestal and surface mounting installations. PRELIMINARY - Motorola Internal Use Only SLE*-* Installation and Operation Manual...

LL-SLE-HMS-*/*. (Figure 2-8 illustrates the location of the optional ICS). Please consult your Motorola sales representative for the availability of LL-SLE-HMS-*/*. To properly install the LL-SLE-HMS-*/*, the deeper housing cover (SLE-LID/SM is required. The ICS provides a means of isolating sources of ingress from a centralized location. Using a downstream command through the LIFELINE status-monitoring system, you can attenuate the return path through the line extender by 6 dB or by 38 dB.

This is caused by factors such as walkout errors, worst-case data utilization during design, and temperature variation from 70°F. Perform a bench alignment. Pre-aligning the SLE*-* response on the bench (Section 4, “Bench Testing”) for a system signature simplifies field alignment.

Return levels used for alignment are not necessarily operational system levels. These levels vary from system to system due to differences in equipment, architectures, and design philosophies. For an in-depth analysis and discussion of the return path, refer to Motorola reference guide Return Path Level Selection, Setup, and Alignment Procedure.
To avoid possible injury to personnel or damage to the equipment, remove 60/90 volt AC power from the system before you remove any components from the housing. The SLE*-* is shipped from the factory configured for 38 through 90 VAC powering as described in Section 2, “Overview.” SLE*-* Installation and Operation Manual PRELIMINARY - Motorola Internal Use Only...
Section 4 Bench Testing Motorola’s recommended procedure for placing a new SLE*-* into service is to fully test it on the bench before it is field installed. There are specific alignment procedures that ensure proper functioning of all components and simplify final installation. If the SLE*-* is properly aligned on the bench only minor adjustments may be required in the field.
The equipment typically used for testing the SLE*-* consists of a network analyzer such as the HP 8712 or 8713 series, a 60/90 VAC bench power supply, a cable simulator, a Motorola model SSP-PIN power combiner, and a variety of jumper cables, adapters, and fittings.

The result is the peak-to-valley (P-V) flatness. Some improvement is possible by adjusting the flatness controls on the LDR/*/III board as described in Section 3, “Amplifier Setup,” Flatness Control. Figure 3-3 illustrates the location of these controls on the LDR/*/III board. PRELIMINARY - Motorola Internal Use Only SLE*-* Installation and Operation Manual...

E-GaAs SLE*-*s, this should not be a major concern assuming the pad value is reasonable. It is recommended that you contact Motorola’s TRC or your account representative for specific information regarding use of the midstage pads.
Specifications are valid over the given bandpass and operating temperature range of −40°F to +140°F (−40°C to +60°C).
