Chapter 2 Installation Instructions
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 before 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.
See 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.
Product Dimensions
This section outlines the space requirements for your 1715 Redundant
I/O System.
DIN Rail Mounting Dimensions
The system requires free space of at least 140 mm deep (5.51 in.) from front to
back between the rear panel of an enclosure and the inside of an enclosure
door.
IMPORTANT
The insertion and removal of modules does not disturb the
electrical connections with field devices.
