Safety Guidelines
Caution
Observe all instructions and cautions in the user documentation. Using
the model in a manner not specified can damage the model and compromise the
built-in safety protection. Return damaged models to NI for repair.
Safety Voltages
Connect only voltages that are below these limits.
Channel-to-channel isolation
Continuous working voltage
1
100 V peak
Channel-to-earth isolation
Continuous working voltage
100 V peak
Transient overvoltage
2
920 V peak
Caution
If you are using the SLSC-12251/12252 with voltages greater than 60
V
dc
, the SLSC chassis must be made touch safe by panel mounting it in a closed
rack to prevent user access to the rear of the device.
These test and measurement circuits are rated for measurements performed on circuits not
directly connected to the electrical distribution system referred to as MAINS.
MAINS is a hazardous live electrical supply system to which equipment is designed to be
connected to for the purpose of powering equipment. This product is rated for measurements
of voltages from specially protected secondary circuits. Such voltage measurements include
signal levels, special equipment, limited-energy parts of equipment, circuits powered by
regulated low-voltage sources, and electronics.
1
Working voltage rating is the highest RMS value of the AC or DC voltage across the insulation that
can continuously occur when the equipment is supplied at rated voltage.
2
The short duration overvoltage of a few milliseconds or less, oscillatory or non-oscillatory, usually
highly damped.
