Chapter 2 Installation Instructions
Install Summary The 1715 Redundant I/O System is a modular system. The adapter and I/O base
units snap together by using mating connectors and retaining clips to form the
backplane.
The base units provide the interconnections for power, adapter, and I/O data.
Once connected, the base units form a single, mechanical assembly, or backplane.
Step 1: Enclosure DIN Rail Assembly
The 1715 Redundant I/O System is assembled on DIN rails within an enclosure.
After deciding on an enclosure, install the DIN rails prior to building your
system.
Step 2: Build the System
After assembling the DIN rail enclosure, follow these steps in this order to build
your redundant I/O system.
1. Mount a 24V, user-supplied, power supply.
Refer to the instructions that came with the power supply.
2. Mount the adapter base unit onto the DIN rails.
3. Mount the I/O base units onto the DIN rails.
4. Insert retaining clips to connect adapter and I/O base units.
5. Install anchor end stops onto the DIN rails.
6. Mount termination assemblies to the base units.
7. Mount I/O expansion cable, if needed.
8. Wire the adapter base.
• Connect to power.
• Wire the ground.
• Connect to field wiring.
9. Connect the adapter to the Ethernet network.
10. Module keying/verify coding peg positions.
11. Install the adapter redundant module pair.
12. Install the I/O modules.
13. Install slot filler covers over unused slots.
IMPORTANT The insertion and removal of modules does not disturb the electrical
connections with field devices.
