Notes:

• The termination block and accessory port connector need to be removed and replaced as a unit. Do NOT attempt to remove or replace only one at a time.

• During this procedure, you will need to keep track of individual wires and their positions within connectors. The wires should have labels to help reinstall them in the correct connector slots. If you notice a wire does not have a label when you remove it, we recommend that you label it and note the corresponding connector slot.

• Some ROVs may have a green/yellow ground wire connected to the termination block. This has been removed in newer models that have the latest pressure sensor. If the ROV has a white housing pressure sensor, the ground wire should not be used. If the ROV has a black housing pressure sensor, the ground wire must be used.
