Installation Instructions for Allen-Bradley 1734-FPD POINT I/O Field Potential Distributor Module

Quick guide from the manual

The 1734-FPD and 1734-FPDK Field Potential Distributor Modules are designed to break field power distribution within a POINT I/O system. This allows for logical or functional partitioning of I/O modules. The module is intended for use in Pollution Degree 2 industrial environments and must be mounted within a suitable enclosure.

Installation

The module is designed for DIN rail mounting. Ensure the DIN rail is zinc-plated chromate-passivated steel to ensure proper grounding. To install:

• Position the module vertically above the DIN rail.
• Engage the interlocking pieces with the unit on the left.
• Press down firmly to install the module on the DIN rail until the locking mechanism snaps into place.

Removal

To remove the module, you must first remove any I/O module installed in the base to the right:

• Pull up on the RTB (Removable Terminal Block) removal handle to remove the terminal block.
• Use a small-bladed screwdriver to rotate the DIN rail locking screw to a vertical position to release the locking mechanism.
• Lift the module straight up to remove.

Wiring

The module supports both 12/24V DC and 120/240V AC applications. Ensure power is removed or the area is nonhazardous before connecting or disconnecting wiring to avoid electric arcs.

12/24V DC Wiring

• Terminal 2: Chassis Ground
• Terminal 4: Common
• Terminal 6: +V DC

120/240V AC Wiring

• Terminal 2: Chassis Ground
• Terminal 4: L2/N (Neutral)
• Terminal 6: L1 (120/240V AC)

Safety and Maintenance

This equipment is sensitive to electrostatic discharge (ESD). Always touch a grounded object before handling and use a static-safe workstation if available. Do not attempt to repair the module; return it to the manufacturer if damaged. Use only a soft, dry anti-static cloth for cleaning; do not use cleaning agents.
