2. Safety
The units have been designed, built and tested using state-of-the-art engi-
neering, and have left the factory in a technically and operationally safe
condition. If used improperly, the units may nevertheless be hazardous to
personnel and may cause injury or damage. Read the operating instruc-
tions carefully and observe the safety instructions.
2.1 Identification of risks and hazards
Possible risks and hazards resulting from the use of the units are referred
to in these operating instructions by the following symbols:
Warning!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in serious personal injuries.
Caution!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in damage to property.
Ex Warning!
Only for units with Ex approval.
This symbol denotes the special conditions which must be observed when
operating the units in explosion hazard areas as specified in the
approvals.
2.2 Technical advance
The manufacturer reserves the right to make changes to the technical
specifications without prior notice in order to adapt the units to state-of-
the-art engineering. Eltex will provide the latest information on any
changes or modifications in the operating instructions on request.
2.3 Proper use
The TUE Terra-Control Ground Monitoring System must be operated only
for the purpose of static ground connection.
The active component Terracompact II TCO030 is an associated electrical
device in accordance to the standards EN 60079-0 and EN 60079-11 and
must be placed outside the explosion hazard area. The Terrabox TCB030
component is approved for installation in the explosion hazard area (see
chapter 8 Technical specifications).
The Terra-Control ground monitoring systems are designed for operation
with specific Eltex contact clamps of the Series 70 and
TERRA
CLAMP as
well as 601KR/_ cable rewinders. These contact clamps provide high
degree of safety and the best possible ground connection in terms of static
electricity.
