Installing Your Module - Allen-Bradley SLC 500 1746-NI4 Installation Instruction

Installing Your Module

All modules are mounted in a single slot. Remember that in a modular system the
processor always occupies the first slot of the first chassis.

IMPORTANT
1. Verify that all switches are set correctly for the application.

2. Align the circuit board of the analog module with the card guide of the chassis
as shown below.
3. Slide the module in until both top and bottom retaining clips are secured.
4. To remove the module, depress the retaining clips at the top and bottom of the
module and slide the module out.
Never install, remove, or wire modules with power applied to
the chassis. Also, do not expose analog modules to surfaces or
other areas that may typically hold an electrostatic charge.
Electrostatic charges can destroy the analog circuitry.
The potentiometer sets the voltage during factory calibration
to 2.5 volts. It is set and sealed at the factory and does not
require any adjustments.
Care should be taken to avoid connecting a voltage source to a
channel configured for a current input. Improper module
operation or damage to the module can occur.
