1.2 Safety recommendations

When using the weighing equipment in surroundings with increased safety

requirements, the corresponding regulations must be observed.

The weighing machine may only be used with the power adapter supplied

exclusively for use with the weighing machine.

Before inserting the power adapter, the user must ensure that the operating

If not, please contact Customer Service at the address above.

If the power adapter or its cable is damaged, the weighing machine must

immediately be disconnected from the electricity supply (pull out the power

adapter).

The weighing machine may only be operated from mains electricity supply with

a power adapter which is in perfect condition.

the weighing machine without danger, the weighing machine is to be

immediately unplugged from the electricity supply (pull out power adapter) and

secured against inadvertent operation.

In carrying out maintenance work, it is essential to follow the recommendations

in Chapter 6: Maintenance and service.

The weighing machine must not be operated in an area subject to explosion

risks.

Care must be taken when weighing liquids to ensure that no liquid is spilled

into the inside of the weighing machine or into connections on the rear of the

equipment or the power adapter. If liquid is spilled on the weighing machine, it

must immediately be unplugged from the mains electricity supply (pull out

power Adapter).

The weighing machine may only be operated again after it has first been re-

checked by a service technician.
