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 module.
Caution
Ensure that devices and circuits connected to the module are
properly insulated from human contact.
Note
When module terminals are hazardous voltage LIVE (>42.4 V
pk
/
60 V DC), you must ensure that devices and circuits connected to the
module are properly insulated from human contact. You must use the
NI-9940 connector backshell kit with the NI-9264 with spring terminal to
ensure that the terminals are not accessible.
