Safety guidelines
You can connect hazardous voltages to the USB-3101FS screw terminals. A hazardous voltage is a voltage
greater than 42.4 V
pk
or 60 VDC to earth ground. Take the following precautions if you connect hazardous
voltages to the USB-3101FS:
Caution! Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local
electrical standards.
Caution! Do not mix hazardous voltage circuits and human-accessible circuits on the same device.
Caution! Make sure that devices and circuits connected to the USB-3101FS are properly insulated from
human contact.
Caution! When device terminals are hazardous voltage LIVE (>42.4V
pk
/60 VDC), ensure that devices and
circuits connected to the USB-3101FS are properly insulated from human contact. Use the
ACC-107 backshell with 10-position connector block to ensure that the terminals are not
accessible.
