4. First, install the GPR Pulse Input cable, and then the Battery Interface cable, onto the GPR
circuit board connectors as shown in Figure 11 - 10.
U WARNING: The GPR Pulse Input cable MUST be installed prior to installing the Battery cable.
Do NOT disconnect the Battery cable after it has been installed. Disconnecting the battery
may cause unwanted pulses to be counted by the GPR. If the battery is disconnected,
reprogram the GPR to clear any unwanted pulse counts, then reconnect the battery.
U WARNING: Substitution of components may impair the suitability for Class I, Division 2
applications. Replace battery only with Landis+Gyr part number 40-1590H.
5. Liberally apply the compound to the back of each cable connector, forcing the compound into
each hole where the wires exit the connectors. The GPR circuit board and cable connectors must
be completely covered as shown in Figure 11 - 10. A cotton tipped swab may be used to force
the compound between each wire and into each connector hole.

6. Arrange the GPR Pulse Input and Battery Interface cables as shown in Figure 11 - 11. The cables
must not interfere with or block the GPR antenna.
A CAUTION: The GPR Pulse Input cable must be inserted into the GPR enclosure strain relief
slot as shown. The shrink tubing on the cable must be inserted into the strain relief slot.
7. Gently press the cable downward into the strain relief slot at midpoint of the heat shrink tubing
as shown in the following figures.
