COMMSCOPE L4A-HMDM-6M-P-SGW HELIAX Jumper Installation Guide

COMMSCOPE L4A-HMDM-6M-P-SGW HELIAX Jumper

Product Information

• The product is a cable connector used for installation in a communication infrastructure. It is designed to maintain a straight cable length and prevent stress at the cable/connector junction. The cable has specific bend radius requirements based on its type.
• The product includes coupling nuts for attaching the connector, and the tightening torque varies depending on the connector interface type. The product also includes a boot that should not be pulled back forcefully or with a force greater than 50N (11 lbs).
• The connector interface threads and O-rings are designed for malleability without any supplementary treatment. The use of supplementary lubricants/oils may void the warranty and affect the performance of the connector/assembly.

For technical support, customers can contact CommScope through their toll-free number or open a ticket on their website.

Product Usage Instructions

1. Maintain a 2-inch straight cable length behind the cable. Hold the cable adjacent to the connector to prevent stress at the cable/connector junction.
2. Ensure that the cable does not exceed the minimum bend radius specified in the single bend radius table provided in the manual.
3. Route and form the cable in place before attaching the coupling nuts.
4. Do not twist the cable into position.
5. When attaching the jumper connector, do not leave the opposite end hanging unattached.
6. Tighten the coupling nuts according to the manufacturer’s instructions and the specified tightening torque based on the connector interface type.
7. Avoid pulling back the boot forcefully or by using a force greater than 50N (11 lbs).

It is recommended to secure the jumper at intervals of 1m from either end and at intervals of 0.5m to 1.5m based on hanger spacing considerations to avoid excessive wind vibration. For further assistance or technical support, customers can contact CommScope through their provided contact details.

Installation of HELIAX® Jumper Products

1. Maintain a 2-inch straight cable length behind the cable.
   • Do not hold the connector and bend the cable directly behind it, rather hold the cable adjacent to the connector to keep stress from the cable/connector junction.

2. Do not exceed the cable minimum bend radius.
   Single Bend Radius **Table***

   Cable| Radius, inches
   FSJ1| 1.0 (25.4mm)
   LSF2| 1.0 (25.4mm)
   FSJ4 / RSJ4| 1.25 (31.8mm)
   LDF1| 1.5 (38.1mm)
   LDF2| 1.6 (40.6mm)
   LDF4| 2.0 (50.8mm)

Note : Requires use of mandrel to achieve single bend radius.

3. Route and form the cable in place before attaching the coupling nuts.
4. Do not twist the cable into position.
5. Do not attach the connector coupling nut of one jumper connector and leave the opposite end hanging unattached.
6. Tighten the coupling nuts per manufacturer or industry specifications.
   • The use of a torque wrench on the coupling nut is recommended.
   • Use two wrenches. Place the torque wrench on the coupling nut, while simultaneously keeping the connector front body stationary using a second wrench. This will properly activate/compress the sealing gaskets to keep moisture out and allow for the most consistent and best possible electrical results.
   • OOn-site under-torqued coupling nuts are a leading cause of sweep difficulties.
     Connector Interface Type| Tightening Torque
     ---|---
     7/16 DIN| 18-22 lb-FT (25-30 Nm)
     Type N| 15-20 lb-IN (1.7-2.3 Nm)
     4.1/9.5 DIN| 88-132 lb-IN (10-15 Nm)
     4.3-10| 44-70 lb-IN (5-8 Nm)
     NEX10| 35-44 lb-IN (4-5 N*m)
7. Do not pull the boot back and do not pull the boot back by coupling the nut with a force greater than 50N (11lbs).

NOTE : Connector interface threads and O-rings are designed for mate ability without ANY supplementary treatment to threads or O-rings. If any type of supplementary lubricants/oils are used, the warranty will be void, and connector/assembly performance may be affected. CommScope recommends securing the jumper to avoid excessive wind vibration, at 1m from either end and intervals from 0.5m ~ 1.5m based on hanger spacing considerations.
