Risk of electric shock
It is prohibited to disconnect the earthed protective connection inside or outside of the
instrument!
If it is assumed that a safe operation is no longer possible, the instrument must be shut
down and secured against any unintended operation.
Safe operation can no longer be assumed as follows:
●
Instrument shows visible damage
●
Instrument includes loose parts
●
Instrument no longer functions properly
–
After an extended period of storage under unfavorable conditions (e.g. out-
doors or in damp rooms)
–
After rough handling during transport (e.g. packaging that does not meet the
minimum requirements by post office, railway or forwarding agency)
Exceeding the low voltage protection
Use insulated wires and not bare wires for the terminal connection.
For the series connection of all output voltages of the 35 V variant, it is possible to
exceed the low voltage protection of 42 V. Please note that in this case any contact
with live components is life-threatening. It is assumed that only qualified and trained
personnel service the power supplies and the connected loads.
Before switching on the product, it must be ensured that the nominal voltage setting on
the product matches the nominal voltage of the AC supply network. If it is necessary to
set a different voltage, the power fuse of the product must be changed accordingly.
4.1.2
Intended Operation
The instrument is intended only for use by personnel familiar with the potential risks of
measuring electrical quantities.
For safety reasons, the instrument may only be connected to properly installed safety
socket outlets. Separating the ground is prohibited.
The power plug must be inserted before signal circuits may be connected.
Use only the power cord included in the delivery package. See
on page 17.
Before each measurement, measuring cables must be inspected for damage and
replaced if necessary. Damaged or worn components can damage the instrument or
cause injury.
