The following diagram shows how the cable system components are connected when wired
directly to a battery. A ground wire must be installed between the negative terminal of a free
standing battery and a ground point on the drill rig. The ground point can be the negative
terminal on the drill rig’s battery or a metal contact point on the drill rig or drill stem.

MFCB Wiring Connections
* This cable is available as part number 460-3825-00.
** This cable, part number 460-0002-00, is supplied with the MFCB.
The compression fitting shown in the preceding diagram is a non-DCI part required to seal
the transmitter from the drilling fluid. Contact a drill or tooling manufacturer for information on
compression fittings.
Connecting to the Remote Display
For a
freestanding
remote display, use the cable with identical four-hole round connectors at
both ends. Align the key marks in the connector with the key slots in one of the power ports,
then push in and rotate the connector clockwise until it locks into place with a snapping
sound.
For a
panel-mounted
remote display, remove the display from the console and unplug and
remove the
power cord from the drill rig’s power port. Plug the rectangular orange four-hole
connector of the new power and data cable (shown on page 5) into the remote display
’s
power port and install the other end into one of
the cable box’s power ports. Your drill rig
dealer can provide additional assistance if needed.
