Connect Spare E-Tap 5 in Junction Box

This document provides instructions for connecting a spare E-Tap 5 fiber optic communications module in the upper junction box of a Canrig Converteam top drive. It details that excessive vibrations during drilling can cause failures in the fiber optic cables on the top drive. To address this, a spare E-Tap 5 module and connection were added to the upper junction box which experiences less vibration. The 3-step procedure explains how to disconnect the original fiber optic cable and connect the spare module instead to bypass a failed component and restore communications.

Description: Procedure to connect spare E-Tap 5 in upper Junction Box

BACKGROUND INFORMATION
During top section and rough drilling, the topdrive may experience excessive vibrations. A common
failure associated with excessive vibrations is the fiber optic communications on the topdrive. The
most common failure is E-Tap 5 (176) in the flex I/O junction box on the topdrive. We have
upgraded the topdrive to include a spare E-Tap 5 (176) in the upper junction box of the torque guide
because the upper junction box experiences less vibrations than the topdrive. The upgrade
includes:
1. Adding a spare E-Tap 5 (176) in the upper junction box.

2. Adding a fiber optic receptacle to the upper junction box.

3. Adding a spare Ethernet cable inside the service loop from the spare E-Tap 5 (176) in
upper junction box to the flex I/O junction box.

Ethernet cable connects Ethernet


communication adapter to E-Tap 5 in
upper junction box (cable goes
through the service loop).

The following procedure explains how to connect the spare E-Tap 5 (176):

1. In the Upper Junction Box of the torque guide:


Above the upper junction box, disconnect the fiber optic cable connections.

Connect Fiber Optic to


Receptacle Here

Disconnect here

From Lower Junction Box

Connect the cable from the lower junction box to the new fiber optic receptacle on
the upper junction box. (Properly protect and secure the connector from the service
loop side)
2. In the topdrive flex I/O junction box:
- Disconnect the Ethernet cable from the Ethernet I/P adapter (177).

- Connect the spare Ethernet cable from the service loop.

This will by-pass the original E-Tap 5 and fiber optic cable in the service loop. The topdrive will
respond slightly slower due to the longer Ethernet cable used in the service loop.
