3Assemble the splice enclosure following the instructions furnished with the enclosure.

CAUTION!

It is important that the connections at the headend be duplicated. If they are different from the above recommendations, follow the scheme used for the headend connections.

4Complete the splicing and installation of the splice enclosure. Suspend the extra cable from the messenger using locally accepted methods. Commonly used methods include suspending it from the messenger along its entire length, and/or fashioning a figure eight coil and suspending it from the messenger.

If you intend to install the housing at a later time, protect the end of the service cable with the compression fitting and the fiber connectors from dirt and moisture.

DANGER!

To avoid possible injury to personnel or damage to the equipment, remove 60/90 volt ac power from the system before you install the node.
