How to reattach the grabber
To use the ROV with the grabber again, you must reattach the grabber cable.
You will find it easier to turn the ROV upside down or onto its side for this
procedure.
1.
Ensure the ROV is powered off
and follow the steps in the previous section
to release the vacuum from inside the ROV.
2.
Put your grabber into its operational position so that you can find the best
route for the cable. Also make sure that the grabber plug can reach its port
in both front and back mounting positions.
3.
Lubricate the o-rings on the grabber cable plug by applying a thin coating of
silicone grease.
4.
Unscrew the collar from the port plug in the ‘GRAB’ port and take the port
plug out.
5.
Line up the grabber cable plug with the port. The grabber cable plug
contains a 3-way pin. To ensure it is oriented correctly, align the pin
protruding from the plug into its hole in the port; the hole is shown in the
picture below. You might need to shine a light onto the port to see it.

6.
Insert the grabber cable penetrator into the port and push it in as far as it will
go, once you are sure the pin is aligned. Then, screw in the black knurled
collar until it is fingertight.
7.
Check that the ROV can hold a vacuum. Apply a vacuum to the ROV
(875mBar) and monitor the pressure on the Control Station to ensure it is
maintained for 10 minutes. For instructions, see the Boxfish ROV Owner’s
Manual.
