Safety Guidelines
The following cautions contain important safety information concerning hazardous voltages
and connector blocks.
Caution
Do not connect hazardous voltages (>30 V RMS/42 V peak/60 V DC).
Refer to your product documentation for information about the electrical limits of
your device or module.
Caution
