Safety Inspection
If there is any indication that safe operation of the balance is no longer warranted:
t Disconnect from the supply voltage: Unplug the power cord from the outlet�
t Secure the AC adapter and cord so that they cannot be used�
Safe operation of the AC adapter is no longer ensured:
– The AC adaptor or the mains connecting lead shows visible damage�
– The AC adaptor no longer functions properly�
– Following extended storage in adverse conditions�
In this case, notify the Sartorius Service Center�
Maintenance and repair work may be performed only by authorized service
technicians who have access to the required maintenance manuals and instructions
and who have received the necessary training�
We recommend that the AC adapter be inspected by a qualified service technician
with regard to the following:
– Leakage current: <0�25 mA measured with a properly calibrated multimeter�
– Insulation resistance >7MOhm as measured with a constant voltage of at least
500 volts at a 500 kOhm load�
The duration and number of checks should be determined by a qualified Sartorius
service technician on site based on specific ambient and operating conditions (once
a year as a minimum)�
