In remote Breakout Box installations, Figure 4, the 6500 Monitor uses a standard MS-8
connection to interface with the 6 foot (1.8 m) 6507 Patch Cable that is connected in the 6508
Junction Box. The Junction Box is then connected by conduit and three- conductor cable to the
Breakout Box(s). The customer is advised to supply rigid conduit and 18 AWG or heavier
shielded multi-conductor cable to connect between the Junction Box and the Breakout Box at the
Sonde installation site. This configuration allows a maximum cable length of 250’ between the
6500 Monitor and the Sonde(s). The cable from the junction box should be landed to TB-1 in the
breakout box. The MS-8 connectors for Sonde hookups are pre-wired to TB-2 and TB-3. See
Figure 12 for further information.
