When Safe Operation can no Longer be Assured
The device is designed and tested in accordance with EN 61010 Part 1, "Safety
Provisions for Electrical Measuring, Control, Regulation and Laboratory
Instruments" and has been shipped ready for safe operation. To maintain this
condition and to assure safe operation, read and follow the safety information in
this manual. Failure to do so can put persons at risk and can lead to device
damage as well as damage to other systems and devices.
The protective lead (ground) should be attached to the protective lead connector
before any other connection is made.
The device can be hazardous if the protective lead is interrupted inside or outside
the device or if the protective lead is disconnected.
Current-bearing components can be exposed when the covers or parts are
removed, even if this can be done without tools. Current can be present at some
connection points.
All work on a device that is open and connected to power should only be
performed by trained personnel who are familiar with the risks involved.
If it is apparent that safe operation is no longer possible, the device should be
taken out of operation and secured against unauthorized use.
The possibility of safe operation is excluded:
If the device is visibly damaged,
If the device no longer operates,
After prolonged storage under adverse conditions,
After severe transport stresses.
