Dear Customer,
The Eltex cable rewinders of series 601KR ensure that the ground cable is
safely reeled back after use, protecting it from damage and dirt.
The aluminum cable rewinder is made of impact-proof aluminum and is
mounted with an assembly bracket. This allows the cable rewinder to be
turned into the direction of the cable run making unwinding and rewinding
easy. At type 601KR/AW the rubber cable outlet prevents moisture and
dirt from penetrating the housing. The built-in cable stop mechanism
allows the cable to be locked in place and released as required.
The plastic cable rewinder is encased in a robust and sturdy plastic
housing. The cable outlet is fitted with four cable guide rollers for easy
cable guidance.
The cable rewinders and the clamp holder are designed for wall mounting
and may be used in zones with potentially explosive atmospheres.
Please read the operating instructions carefully before starting the
instrument. This will help you prevent personal injuries and damage to
property.
Please 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.

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.
For warranty conditions, please refer to the General Terms and Conditions
(GTC), see www.eltex.de.
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.
Ex!

2.3 Proper use
Active grounding
The cable rewinder series 601KR must be used only for static grounding
and must be connected to the appropriate Eltex ground monitoring
systems.
The application area are for example: refilling and filling stations, agitators
or dryers for liquid or powdery substances, and in conveyor and
transportation equipment with potentially explosive atmosphere.
The cable rewinders series 601KR are not suitable for use in a saline
environment (e.g. sea ports).
The manufacturers will not assume any liability and warranty if the units
are used improperly or used outside the intended purpose.
Modifications or changes made to the devices are not permitted.
Use only original Eltex spare parts and equipment.

2.4 Work and operational safety
Warning!
Carefully observe the following notes and the complete chapter 2 "Safety”,
page 7!
• The local standards, rules and regulations relating to the installation
and operation of electrical appliances in potentially explosive atmos-
pheres must be observed.
• Appliances designed for use in potentially explosive atmospheres must
not be modified. The technical specifications for ambient conditions and
operation must be maintained and observed (see chapter 6 "Technical
specifications”, page 19).
• Electrical systems in potentially explosive atmospheres must always be
in perfect technical condition. Defects must be rectified immediately
(see chapter 4 "Operation”, page 18).
• Any work involving the units must be carried out by qualified electrici-
ans (see chapter 3 "Installation and assembly”, page 10, chapter 5
"Maintenance”, page 18).
• The unit may only be used by qualified personnel trained for explosion
hazard areas.
• Please note the type plate indicating the connection data (supply vol-
tage) of the units (see chapter 4 "Operation”, page 18).
• A „Connect/Disconnect Approval“ by the plant operator must be
obtained before carrying out any installation, assembly, service, repair
or maintenance work in potentially explosive atmospheres. Make sure
that there is no potentially explosive atmosphere existing in the working
area. Ensure adequate ventilation and/or screening (see chapter 3
"Installation and assembly”, page 10, chapter 5 "Maintenance”,
page 18).
• The equipotential bonding line to the housing of the cable rewinders
must be connected permanently according to the universal rules of
electrical engineering. The terminal cross-section must equal at least
the cross-section of the power supply of the ground testing device (see
chapter 3.3 "Electrical connection of the cable rewinder”, page 15).
• The housing of the cable rewinders may not be opened; the internal,
pre-tensioned spring represents a significant risk. Only the cap may be
removed to configure the stop mechanism (see chapter 3.3 "Electrical
connection of the cable rewinder”, page 15).
• Perform regular checks to ensure that the cable and the insulation
show no tears or abrasion that could impair the cable's insulation or
functioning (see chapter 5.1 "Cable rewinders”, page 18).

3. Installation and assembly
When installing the systems in potentially explosive zones, every possible
precaution must be taken to ensure that no explosive atmosphere exists!
3.1 Aluminum cable rewinder
The aluminum cable rewinder is attached to a wall, column or ceiling via
the installation bracket as shown in Fig. 2. Roofing must be provided when
installing the unit outside. Select a suitable installation height to make sure
that the ground clamp is within easy reach and does not make contact
with the floor. The cable rewinder type 601KR/AW may be turned by 320°
and types 601KR/DW and 601KR/EW by 170° around its installation axis.
The cable rewinder is suitable for hazardous location area.
