Installation Guidelines

• Chassis Installation: Align the controller with the chassis slot guides and slide it in firmly until the top and bottom latches snap into place.
• Battery Connection: Ensure the 1756-BA2 battery is properly connected to the controller before initial power-up to safeguard user memory.
• Grounding: Connect the ControlLogix chassis to functional earth ground using low-impedance grounding conductors to minimize electromagnetic interference.
• Cable Routing: Maintain separation between RS232 communication cables and high-voltage AC or motor power lines to preserve signal integrity.
