Dear customer,
The controlled grounding principle used in the TUE Terra-Control Ground
Monitoring System ensures that static charges developing in potentially
explosive atmospheres, e.g. during loading, discharging or refilling are
safely avoided. This means that the risk of ignition caused by uncontrolled
static discharges is eliminated at source.
No impedance grounding and no large conductor diameters, normally
needed in electrical machine construction, are required.
Static charges are caused by the contact and separation of material
surfaces, e.g. when pumping liquid or powdery materials from one
container to another. If no leakage device is available to lead these
charges to ground, extremely high charge potentials may develop.
Deflagrations or even explosions caused by sparking can result in
substantial damage or personal injury.
Objects are considered to be adequately grounded if their ground leakage
resistance is not greater than 10

. The Eltex Terra-Control Ground
Monitoring System guarantees a safe and reliable ground connection.
Used in combination with the Eltex ground clamps and the cable rewinders
the system provides the ultimate ground connection.
The Terra-Control components monitor the connection to the bonding
conductor and the contact across the ground clamps. This function is
controlled by a relay. This relay allows an isolation mechanism to be
implemented which, as long as the ground clamp is connected to the
container or bin, releases the filling or refilling process, for instance. If the
clamp is removed or slips off, or if the ground connection is interrupted,
filling stops automatically.
Please read these instructions carefully before starting the unit. This will
help you prevent personal injuries and damage to property.
Simply give us a call if you have any suggestions, proposals or ideas for
improvements. We greatly appreciate the feedback from the users of our
appliances.
