34 Install and Wire the Module
Touch a grounded object to rid yourself of electrostatic charge
before handling the module.
Handle the module from the front, away from the backplane
connector. Do not touch backplane connector pins.
Keep the module in its static-shield bag when not in use, or
during shipment.
NR4 Power Requirements
The RTD module receives its power through the SLC 500 chassis
backplane from the fixed or modular +5V dc/+24V dc chassis power
supply. The maximum current drawn by the module is shown in the
table below.
When you are using a modular system configuration, add the values
shown in the table above to the requirements of all other modules in
the SLC chassis to prevent overloading the chassis power supply.
When you are using a fixed system controller, refer to the Important
note about module compatibility in a two-slot expansion chassis on
page 35.
