• Install the power supply in the safe area
near a wall socket.
If required, the power supply unit can be
permanently fixed by using the mounting
plates and the 4 screws.
• Route the power line cable and the cable
to the scale so that they are protected
against damage. Cables must not be
kinked or bent at sharp angles.
• Plug the power plug into the wall socket
of the building electrical installation.
Note: The type 21201489 of the PS-EX1
(230 V Euro) is delivered without plug. Fit a
3-pole plug to the cable observing the lead
colors:
yellow/green lead
brown lead
blue lead
As neither the power supply unit nor the
scale have an on/off switch, the power plug
serves as a power disconnecting device.
The scale is ready for operation as soon as
the power plug is plugged in.
