E.
make sure the instrument can not be activated accidentally by another person during
connection of the output cable;
F.
connect the output cable clamp to the monitored buried utility (cable wire, pipeline, link
cable);
G.
connect the second clamp of the output cable to the grounding, cable armor or to the
grounded rod;
H.
connect the output cable connector to the output socket of the deactivated generator;
I.
if there are other persons near current conductive parts alert them about voltage supply
by saying «Appling voltage ».
ATTENTION!
When connecting the generator, the latter itself shall be
TURNED OFF!
Personnel safe procedure for work with the generator when disconnecting from the
route
-
turn off the generator power;
-
disconnect the output cable from the generator and close the connector with rubber
plug;
-
conduct the troubleshooting activities (cable digging out, placing the clamp, etc.) only
AFTER the generator is turned off and disconnected from the buried utility
3.3 Generator connection
1). Contact mode of generator connection
This mode guarantees transmission of signal without interference and allows use of low
frequencies.
The connection to buried utility is done by mating
of the output connector of the generator to the
buried utility and grounding rod figure 3.2.
The grounding is carried out in any convenient
place, which should be cleaned from the dirt with
file or sandpaper to the metal. This ensures more
reliable contact of the clamp and buried utility.
Rules for grounding:
- To achieve the maximum tracing distance when
the generator is connected to the buried utility
the grounding shall be arranged at an angle close
to 90 and as far as possible from the route in the
assumed search direction
