2 Safety precautions
Product safety plays an important role at KERN & Sohn.
Non-observance of the following instructions can lead to damage to the weighing
platform and/or injuries.
Before using the weighing platform read these instructions. Store these instruc-
tions for future use.
Take care when transporting or lifting heavy devices.
Only qualified personnel may install and maintain the weighing platform.
Disconnect the weighing terminal from the power supply before carrying out
cleaning, installation and maintenance.
The weighing platform must have stabilized to room temperature before the sup-
ply voltage is switched on.
Do not use the weighing platform in hazardous environments.

At the same time it should be so
stable that no vibrations arise during weighing. This is also to be observed when installing the weighing
platform in conveyor and similar
systems.
• If possible, vibrations from
neighboring machines should not
occur at the site of installation.

Only use original packaging for returning.
Reattach supplied transport securing devices.
Secure all parts against shifting and damage.
No direct sunshine
No strong draught
No excessive temperature fluctuations
Temperature range –10 °C to +40 °C.
3.5 Levelling
Only a weighing platform which is aligned exactly horizontally supplies exact weighing results. The weighing platform has to be levelled during the initial installation and
whenever its location is changed.

4 Operating limits
The weighing platform is designed so robustly that an occasional exceeding of the
maximum weighing load does not lead to damage.
The static bearing capacity, i.e. the maximum permissible load, depends on the type
of load carrying (position A – C). The maximum static bearing capacity may not be
exceeded.
Avoid falling loads, shock loads as well as im-
pacts from the side.
