Installing the RTD Input
Module
This chapter gives you information on:
•
calculating the chassis power requirement
•
choosing the module’s location in the I/O chassis
•
keying a chassis slot for your module
•
wiring the input module’s field wiring arm
•
installing the input module
Before installing your input module in the I/O chassis you must:
Youneed to: As described under:
Calculate the power requirements ofall modules
in each chassis.
Power Requirements, page 2-2.
Determine where to place the module in the I/O
chassis.
Module Location in the I/O Chassis, page 2-2.
Key the backplane connector in the I/O chassis. Module Keying, page 2-3.
Make connections to the wiring arm and ground
your module.
Wiring Your Input Module, page 2-4, and
Grounding, page 2-6.
The RTD input module is sensitive to electrostatic discharge.
!
ATTENTION: Electrostatic discharge can damage
integrated circuits or semiconductors if you touch
backplane connector pins. Follow these guidelines
when you handle the module:
•
Touch a grounded object to discharge static potential
•
Wear an approved wrist-strap grounding device
•
Do not touch the backplane connector or
connector pins
•
Do not touch circuit components inside the module
•
If available, use a static-safe work station
•
When not in use, keep the module in its
static-shield bag
