14 Install and Wire the Modules
Select the I/O Rack Slot 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.
Install the Module 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.
Follow these steps when installing or removing the module.
1. Verify that input configuration switches 1 and 2 are set correctly.
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.
ATTENTION
Never install, remove, or wire modules with power applied to
the I/O rack. Rid yourself of electrostatic charge before
handling the module. Electrostatic discharge can degrade
module performance or destroy analog circuitry.
IMPORTANT
Do not tamper with the module’s factory-sealed potentiometer.
It does not require any adjustments.
ATTENTION
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.
