Safety instructions

1 Safety instructions
In cases where a breakage would cause injury to persons
or damage to equipment, the user must take appropriate
safety measures (such as safety devices to protect
against falls, collapses or overloads). For safe and
trouble‐free operation, load cells must not only be cor
rectly transported, stored, sited and mounted but must
also be carefully operated and maintained.
It is essential to comply with the relevant accident pre
vention regulations. In particular you should take into ac
count the limit loads quoted in the specifications.
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 oper
ated as described in the Mounting Instructions. It is also
essential to comply with the legal and safety require
ments for the application concerned during use. The
same applies to the use of accessories.
Load cells can be used as machine elements (for con
tainer and silo weighing, for example). In these situa
tions, you must make sure that for greater sensitivity, 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 appropriate use.
The layout of the electronics conditioning the measure
ment signal should be such that measurement signal fail
ure does not cause damage.

Safety instructions
4A2447-1.1 HBM: public SP4M
General dangers of failing to follow the safety
instructions
Load cells are state‐of‐the‐art and reliable. Load cells can
give rise to remaining dangers if they are inappropriately
installed and operated by untrained personnel.
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.
Remaining dangers
The scope of supply and performance of the load cells
covers only a small area of weighing technology. In addi
tion, equipment planners, installers and operators should
plan, implement and respond to the safety engineering
considerations 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 technology.
Ambient conditions
In the context of your application, please note that be
cause of the alloy elements used, the high‐strength alu
minum alloy only has limited corrosion resistance 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 re
lease 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 ap
propriate protective measures.

Safety instructions
SP4M A2447-1.1 HBM: public 5
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 agree
ment. Any modification shall exclude all liability 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 conjunc
tion with the safety requirements and regulations 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.
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 particular attention
to the following data from the specifications
Slimit load (EL)
Slimit load at max. Eccentricity
Slimit lateral loading (ELq)
Sbreaking load.
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
operation to protect the load cells against overloading.

Safety instructions
6A2447-1.1 HBM: public SP4M
No forces or moments must be directed via the spring
area during mounting.
Explosion‐proof version (option)
SWhen installing this version, it is essential to comply
with the relevant installation regulations.
SThere must be compliance with the installation condi
tions cited in the Declaration of Conformity and/or the
Type Examination Certificate.
SThe connection cable of the explosion‐proof single
point load cells features free ends (cable configuration
see chapter 4.1, page 10).

evant EC directives (the declaration of conformity is
available at http://www.hbm.com/HBMdoc).
Statutory waste disposal mark
In accordance with national and local environmental
protection and material recovery and recycling regula
tions, old devices that can no longer be used must be
disposed of separately and not with normal household
garbage.
If you need more information about waste disposal,
please contact your local authorities or the dealer from
whom you purchased the product.

3 Mounting and Load application
The load cells are fixed at the mounting bores. For the
recommended screws and tightening torques refer to the
table below:
Max. capacity Thread Min. property class Tightening torque1)
1...36 kg M6 8.8 6 N@m
50...200 kg M6 10.9 14 N@m
1) Recommendedvalue for the stated property class. For screw dimensioning please refer to the
appropriate information given by the screw manufacturers.
Load must not be applied to the side where the cable
connection is located, as this would cause a force shunt.

4.1 Connecting in four‐wire and six‐wire
configurations
When load cells in a six‐wire configuration are connected
to amplifiers with a four‐wire configuration, the sense
leads of the load cells must be connected to the corre
sponding excitation leads.

3 m; 6 m; 12 m)

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 measure
ment accuracy.
4.3 Cable extensions
You must only use shielded, low‐capacitance measure
ment 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 (nomi
nal (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 measuring 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

Electrical connection
12 A2447-1.1 HBM: public SP4M
SAvoid stray fields from transformers, motors and con
tact switches
To ensure the best EMC protection, the load cell, to
gether 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 certi
fication. But you must make sure that the shield of the
connection cable is connected to the shielding housing of
the electronics.
