Installation
In this chapter you will read how to install the 1771–QRD module in the
I/O chassis.
Read this installation section completely before installing the module.
Double check all connections before you begin programming.
WARNING: Disconnect and lock out all power from the
controller and system power supplies before installing and
wiring modules to avoid injury to personnel and damage to
equipment.
Before installing the 1771–QRD Module in the I/O chassis:
1. Calculate the power requirements of all the modules in the chassis.
See the section below titled “Power Requirements”.
2. Determine the location of the module in the I/O chassis. See the
section titled “Module Location in the I/O chassis”.
3. Key the backplane connectors in the I/O chassis. See the sect ion
titled “Module Keying”.
4. Connect the field wiring. See the section titled “Wiring”.
The1771–QRD Module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. It does not require any other
external power supply to function. When planning the system, consider the
power usage of all modules in the I/O chassis to prevent overloading the
chassis backplane or power supply. Each 1771–QRD Module requires 0.50
A at +5VDC. Add this to the requirements of all other modules in the I/O
chassis.
CAUTION: Do not insert or remove modules from the I/O
chassis while system power is on. Failure to observe this rule
may result in damage to the module circuitry.
