Note When using the Remote I/O Shield Set, install the shield rail supports before
mounting the module.
1. Align the REM-11115 over the appropriate bus connector.
Note Verify that the bus connector socket aligns with the socket on the
underside of the module.
2. Press the REM-11115 directly onto the bus connector and DIN rail until it clicks into
place.
Caution Tilting the module when mounting it on the DIN rail will damage the
contacts.

Connection Guidelines
• Always connect analog signals using shielded, twisted pair cables. Unshielded cables
may lead to values outside the specified tolerance limits in environments subject to heavy
noise.
• Connect the cable shield to functional earth ground immediately after the cables enter the
control cabinet.
• Connect the cable shield to a shield bus if you are not using a closed control cabinet.
• NI recommends using the NI Remote I/O Shield Set for optimal shield connection.
• Make sure that devices you connect to the REM-11115 are compatible with the module
specifications.
• Push the wire into the terminal when using a solid wire or a stranded wire with a ferrule.
• Open the terminal by pressing a screwdriver into the spring lever when using a stranded
wire without a ferrule.
