Caution Make sure that devices and circuits connected to

the module are properly insulated from human contact.

Caution When module terminals are hazardous voltage

LIVE (>42.4 Vpk/60 VDC), you must ensure that devices

and circuits connected to the module are properly

insulated from human contact. You must use the NI9932

connector backshell kit to ensure that the terminals are

not accessible.

Figure1 shows the NI 9932 connector backshell.

Note You can use the NI 9932 connector backshell only

with the NI 9201/9221 with screw terminal.
