2.5 Verification information
Note related to scales being used in Germany.
If new or refurbished devices [...] are used, they need to be registered at the notified authority according to state law, at latest six
weeks after setting into operation.
Metrological notes for EU countries
The identification plate of the scale has a CE mark followed by the metrology mark (M + year
two-digital; framed) and the number of the notified body. Until 04/19/2016 the green
used as part of the metrology marking. Such a scale can be started up and operated on-site
provided that it is not connected to an auxiliary device which is subject to metrological approval.
Scales which are connected on site to an auxiliary device which is subject to metrological approval must undergo a conformity assessment or metrological approval. Only then, legal for
trade use is permissible.
was
Scales without metrology mark or control marks may not be used in legal for trade applications.
Scales calibrated for a certain gravity zone (specified on the scale) must not be used in other
zones.
As per legal requirements, the scale user must ensure that the scale is used for its intended
purpose. This includes the observance of legal requirements, especially in case of changes,
amendments and extensions.

Information on verification (early re-verification)
The verification of a scale is executed according to the respective statutory country regulations. The verification validity period for non-automatic scales (up to 3 tons), for example, is
generally 2 years in Germany. The verification validity starts as soon as the device is put on
the market.
When conformity assessment is carried out by Bizerba the scale is
sealed by means of control marks with marking "Gesichert
BIZERBA" on the control marking locations. Verifications must be
carried out by the operator of the scale according to the legal requirements.
Verification information for non-EU countries
The statutory regulations of the specific countries must be observed.
Customer ticket can be deactivated
The device offers the option of suppressing printout of the customer ticket. According to EC
regulation 2009/23/EC for scales, the customer is entitled to a receipt in order to check the
sales transactions in accordance with Appendix 1, No.14. Suppression of the customer ticket
should therefore only be activated if you are sure that there is no customer requirement for
printout of a customer ticket.
2.5.1 Software ID, logbook update
Software ID and update logbook are checked during verification by the approval official.
The software ID for the part of the software that requires verification is to be found in the current EC type approval.
Operating procedure
Keep the <Verification field> operating element held for at least 5 seconds.
Release operating element <Verification field>.

– Written consent for modifications
Changes to the devices require prior written consent of Bizerba. External data dialog between Bizerba equipment and third-party equipment, required hardware and software as
well as test and modification work must be clarified with Bizerba in writing.
2.7.1 Power supply
The installation of the power supply for connecting to Bizerba devices must be carried out in
accordance with the international specifications and the regulations derived from them.
These essentially include the recommendations of at least one of the following commissions:
– NEC (UL)
– International Electro-technical Commission (IEC)
– European Committee for Electro-technical Standardization (CENELEC)
– German Association for Electrical, Electronic and Information Technologies (VDE)
Bizerba devices must be connected to a protective conductor.
Interference suppression
If the mains power supply is subject to electric interference, interference suppression measures must be taken on site, e.g.:
– provision of separate mains line to our devices.
– In case of problems, insertion of capacitively decoupled isolating transformers or other
suppressors into the mains supply lines to Bizerba device.

2.7.2 Wireless LAN device network
Wireless LAN is a wireless network solution, that enables electronic devices to be networked
together without wiring.
The rules on the respective general allocation of frequencies must be observed.
The following instructions must be absolutely observed!
– When wireless networks are deployed, (including those supplied
by Bizerba and those not supplied by Bizerba), the required
transmission power set and frequency channels at Federal state
level must be strictly observed.
– Only wireless hardware is permitted in wireless networks that has
been released for use by the manufacturer in the country in which
it is to be deployed.
– If third parties access the network or wireless network, or if the
network is combined with foreign hardware, Bizerba is not liable
for any damages that result.
2.8 Warranty
Installation, start-up and initial training are carried out by trained staff of the Bizerba sales offices, customer service locations or by companies commissioned by Bizerba.
