Installation Requirements
Before you begin installing the system, take a moment to review these system
installation requirements.
Location
The ProcessLogix system is CSA certified and FM approved non-incendive
equipment for installation in Class I, Division 2, Group A, B, C & D hazardous
(classified) locations. The user must ensure all parts of the system, and any other
equipment in the Division 2 area, are listed for installation in a Class I, Division 2
hazardous (classified) location.
Removal and Insertion Under Power
Some ProcessLogix modules (e.g., I/O and communications modules) as well as the
1757-PLX52 Process Controller module have been designed to permit removal and
insertion under power (RIUP) without damaging the module or interrupting
backplane communications.
Any time electrical connections are made or broken, there is a potential for arcing
or sparking. Do not remove or insert any modules while they are still powered up
when you are in a hazardous (potentially explosive) environment.
ATTENTIO
N
!
The ProcessLogix RIUP feature does not apply to
installations that must conform to Division 2 hazardous
location requirements. Unless the location is known to be
non-hazardous, do not:
•connect or disconnect cables
•connect or disconnect removable terminal blocks
•install or remove modules

Installing the Chassis and Power Supply
Follow this procedure to install the ControlLogix chassis and power supply.
Before You Begin
Before you begin, gather these tools:
•1/8” slotted screwdriver
•1/4” slotted (#2) or phillips screwdriver
•torque screwdriver
•needle-nose pliers
•crimping tool
Set the Line Voltage Input Jumper
Use needle-nose pliers to set the jumper to the correct position.
TIP Ensure that you have properly calculated the backplane
requirements for the power supply you are installing.
IMPORTANT The “HI” and “LOW” positions are marked on the power supply’s
circuit board
for this power supply set jumper to this position

Install the Power Supply
1. Align the power supply’s circuit board with the card guides on the left side
of the chassis
2. Slide the power supply in until it is flush with the chassis.
3. Tighten the screw holding the power supply to the chassis.
4. Connect safety ground from the power supply to the chassis.
5. Use the following illustration to run functional and safety ground
connections from the chassis and power supply to the ground bus.

Connect Power
1. Use #14 AWG 75 °C copper wire.
2. Tighten terminals to a torque of 7 inch-pounds.
3. Connect L1 for the high side of line power.
4. Connect L2 for the low side of line power.
1. Remove the protective label from the top of the power supply.
2. Apply power by toggling the switch on the front of the power supply from
OFF to ON.
ATTENTIO
N
!
Turn off power lines before connecting power. Failure to
do so could cause injury to personnel and/or damage to
equipment.
IMPORTANT Make sure you mount the chassis and complete work on the
panel before you remove the protective label. The label protects
the power supply from metal shavings falling inside the power
supply and damaging it during operation.

Troubleshoot the Power Supply
The ControlLogix power supply has a green LED indicator that remains on during
normal operation. If the indicator is off during normal operation, try the following:
1. Verify that line voltage is within the specified range.
2. Make sure the input voltage jumper is in the proper position (see page 5).
3. If indicator remains off, cycle line power off.
4. Loosen the screws holding the power supply to the chassis.
5. Slide the power supply out so the rear connector is disconnected.
6. Wait 45 seconds and re-apply power.
7. If the indicator turns on, verify that the system module loads are within the
output rating of the power supply and re-install the power supply in the
chassis.
8. If the LED turns off, return the power supply to your local Rockwell
Automation distributor.
Installing the ControlNet Communications Module
Install the 1756-CNB module for ControlNet communications into slot 0 of the
chassis.
1. Align the module circuit board with the top and bottom guides in the
chassis.
2. Slide the module into the chassis. Make sure the module properly connects
to the chassis backplane.
TIP The module is fully installed when it is flush with the power
supply or other installed modules.
To remove the module, push down on the locking clips at the
top and bottom of each module. Slide the module out of the
chassis.
