Introductory Remarks
Safety Instructions
The Signum series scale is in conformance with the applicable directives and
standards. Use of the scale for other than its intended purpose, however, can result
in physical injury or material damage.
Repairs must be performed by service technicians who have been trained at the
factory.
Warning
Electric shocks can cause serious burns and life-threatening injuries.
To avoid electric shock, always disconnect the power cord from
the wall outlet (mains supply) before beginning repair work or
replacement of components. When the scale housing is open, always
use an isolating transformer or a ground fault circuit interrupter.
Make sure no voltage is present in the scale before connecting or disconnecting any
cables to or from it. Otherwise, assemblies or other components may be destroyed.
1 Press eto switch off the scale.
2 Unplug the power cord.
3 Carry out maintenance/repair work.
For further information, please refer to the operating instructions
(WSI6007-e07074.)
