Precautions to Be Taken When Using the Modules
• Do not apply input voltage exceeding the maximum input voltage, withstand
voltage, or allowable surge voltage.
• To prevent the possibility of electric shock, be sure to furnish protective earth
grounding of the SL1400.
• To prevent the possibility of electric shock, be sure to fasten the module screws.
Otherwise, the electrical protection function and the mechanical protection
function will not be activated.
• Do not leave the instrument connected to devices in an environment that may
be subject to voltage surges.
Precautions to Be Taken When Using the Probes
• When measuring high voltages using the 701250 (HS10M12) or the 701251
(HS1M16), use the isolated probe (700929), 1:1 safety cable (combination of
701901 and 701954), or differential probe (700924).
• Be sure to connect the GND lead of the differential probe (700924) to the
functional ground terminal of the SL1400. High voltage may appear at the BNC
connector of the differential probe. Be sure to connect the GND lead to the
SL1400 before connecting the probe to the parameter to be measured.
• When using the 701255 (NONISO_10M12), be sure to fasten the module
screws. Fastening the module screws activates the protection function and the
non-isolation function. It is extremely dangerous if you do not fasten the screws.
In addition, when measuring high voltage above 42 V, be sure to use the
passive probe (701940).
• The BNC part of the passive probe (701940) is made of metal. Therefore, use
the probe at 42 V or less for isolated inputs (701250 (HS10M12), 701251
(HS1M16), etc.) for safety reasons. (Do not connect voltage above 42 V to both
the High and Low sides.)
For non-isolated inputs (701255 (NONISO_10M12), etc.), fasten the module
screws as described before.
• When measuring high voltage using the 701267 (HV (with RMS)), use the
measurement leads (758933) and the alligator clips (751954).
• The measurement category of the 701267 (HV (with RMS)) is 400V-CAT II for
the low side and 700V-CAT II for the high side. Use caution because the
overvoltage tolerance differs between the low and high sides.
Measurement Category
The measurement category of this instrument’s signal input terminals varies
depending on the modules that are installed. Use the instrument within the
scope of the measurement category that corresponds to the module
specifications. Do not use the instrument outside the scope of the measurement
category that corresponds to the module specifications.
Installation Location
• This instrument is designed to be used indoors. Do not install or use it outdoors.
• Install the instrument so that you can immediately remove the power cord if an
abnormal or dangerous condition occurs.
CAUTION
Operating Environment Limitations
This product is a Class A (for industrial environments) product. Operation of this
product in a residential area may cause radio interference in which case the
user will be required to correct the interference.
