1 Safety instructions
In cases where a breakage would cause injury to persons or damage to equip
ment, the user must take appropriate safety measures (such as safety devices
to protect against falls, collapses or overloads). For safe and trouble‐free op
eration, load cells must not only be correctly transported, stored, sited and
mounted but must also be carefully operated and maintained.
It is essential to comply with the relevant accident prevention regulations. In
particular you should take into account the limit loads quoted in the specifica
tions.
Appropriate use
Load cells are designed for metrological applications. Use for any additional
purpose shall be deemed to be not appropriate.
In the interests of safety, load cells should only be operated as described in the
Mounting Instructions. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Load cells can be used as machine elements (for container and silo weighing,
for example). In these situations, you must make sure that for greater sensitiv
ity, the load cells are not constructed with the customary safety factors found in
machine design. Load cells are not safety elements within the meaning of ap
propriate use. The layout of the electronics conditioning the measurement sig
nal should be such that measurement signal failure does not cause damage.
General dangers of failing to follow the safety instructions
Load cells are state‐of‐the‐art and reliable. Load cells can give rise to remain
ing dangers if they are inappropriately installed and operated by untrained per
sonnel.
Everyone involved with siting, starting up, maintaining or repairing a load cell
must have read and understood the Mounting Instructions and in particular the
technical safety instructions.

Safety instructions
4A2443-3.0 HBM: public PW22
Remaining dangers
The scope of supply and performance of the load cells covers only a small
area of weighing technology. In addition, equipment planners, installers and
operators should plan, implement and respond to the safety engineering con
siderations of the weighing technology in such a way as to minimize remaining
dangers. Prevailing regulations must be complied with at all times. Reference
must be made to the remaining dangers associated with the weighing technol
ogy.
Ambient conditions
In the context of your application, please note that because of the alloy ele
ments used, the high‐strength aluminum alloy only has limited corrosion resist
ance if it comes into contact with electrolytes or if there are high and low pH
values. With stainless steel single point load cells, please note that acids and
all materials which release ions will also attack all grades of stainless steel and
their welded seams.
Should there be any corrosion, this could cause the load cell to fail. If this is the
case, the operator must take appropriate protective measures.
Unauthorized conversions and modifications are prohibited
Load cells must not be modified from the design or safety engineering point of
view except with our express agreement. Any modification shall exclude all li
ability on our part for any damage resulting therefrom.
Qualified personnel
Load cells must only be installed by qualified personnel, strictly in accordance
with the specifications in conjunction with the safety requirements and regula
tions listed below. It is also essential to observe the appropriate legal and
safety regulations for the application concerned. The same applies to the use
of accessories.
Qualified personnel means persons entrusted with siting, mounting, starting up
and operating the product, who possess the appropriate qualifications for their
function.

Safety instructions
PW22 A2443-3.0 HBM: public 5
Accident prevention
The prevailing accident prevention regulations must be taken into account,
even though the breaking load is well in excess of the full scale value. Pay par
ticular attention to the following data from the specifications
Slimit load (EL)
Slimit load at max. Eccentricity
Slimit lateral loading (ELq)
Sbreaking load.
CAUTION
Load cells are precision measuring elements and must be handled carefully
during mounting and transportation. Knocking or dropping the load cells can
damage them. Suitable retainers must be used during installation and opera
tion to protect the load cells against overloading. No forces or moments must
be directed via the spring area during mounting.

4.2 Shortening the cable
When the 6-wire configuration is used, the load cell's 6-wire cable can be cut
off without impairing measurement accuracy.

Electrical connection
10 A2443-3.0 HBM: public PW22
4.3 Cable extensions
You must only use shielded, low‐capacitance measurement cables to extend
the cables, making sure that there is a proper connection with minimal contact
resistance.
The cable of a six‐wire load cell can be extended with a cable of the same
type.
4.4 Parallel connection (option)
Only single point load cells with an aligned output (nominal (rated) sensitivity
and output resistance) are suitable for parallel connection. Many of HBM's
single point load cell types are available with this option.
4.5 EMC protection
Electrical and magnetic fields often induce interference voltages in the measur
ing circuit. Therefore:
SUse shielded, low‐capacitance measurement cables only (HBM cables fulfill
both conditions)
SDo not route the measurement cables parallel to power lines and control
circuits.
If this is not possible, protect the measurement cable, in rigid steel conduits,
for example
SAvoid stray fields from transformers, motors and contact switches
To ensure the best EMC protection, the load cell, together with the connection
cable and the subsequent electronics, should be placed in a shielded housing.
Exception
Load cells with shielded, round cables are EMC‐tested in accordance with EC
directives and identified by CE certification. But you must make sure that the
shield of the connection cable is connected to the shielding housing of the elec
tronics.
