Two factors determine where you should locate the module in the
I/O rack: ambient temperature and electrical noise. Consider the
following conditions when selecting an I/O rack slot for the module.
Position the module:
• in a slot away from ac or high voltage dc modules.
• away from the rack power supply if installed in a modular system.
• in the I/O rack lowest in the enclosure for a cooler ambient.
When installing the module in an I/O rack, you do not need to remove
the terminal block from the module. However, if the terminal block is
removed, use the write-on label located on the side of the terminal
block to identify the module location and type. To remove the terminal
block, grasp it on the top and bottom and pull outward and down.
Never install, remove, or wire modules with power applied to
ATTENTION
the I/O rack. Rid yourself of electrostatic charge before
handling the module. Electrostatic discharge can degrade
module performance or destroy analog circuitry.
Do not tamper with the module's factory-sealed potentiometer.
IMPORTANT
It does not require any adjustments.
Follow these steps when installing or removing the module.
1. Verify that input configuration switches 1 and 2 are set correctly.
Take care to avoid connecting a voltage source to a channel

configured for current input. This could result in improper
module operation or damage to the module.
2. Align the module's circuit board with the rack's card guide.
See Installing the Module on page 15.
3. Slide the module in until top and bottom retaining clips are
secured.
