Follow these steps to install the module. 1. Mount the module to a DIN rail. 2. Ground the module. 3. Wire the module. 4. Make connections for safety-related communication. This publication describes these steps in detail. Rockwell Automation Publication 1753-IN003C-EN-P - June 2010... -
Page 5: Mount The Module
DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Rockwell Automation Publication 1753-IN003C-EN-P - June 2010... -
Page 6: Wire The Module
L- terminals are internally connected, so you can daisy-chain 24V DC power from the module to other devices in the panel by using the remaining terminal. ATTENTION: Do not reverse the L+ and L- terminals or damage to the module will result. There is no reverse polarity protection.

- Page 9 Digital input 20 Reference pole LS+, not L+, should be used for short-circuit protection. Each LS+ features individual short-circuit and EMC protection that make it important to use LS+ for only its four related inputs. Rockwell Automation Publication 1753-IN003C-EN-P - June 2010...
- Page 10 With an overload, one or all of the outputs are turned off. When the overload is eliminated, the outputs are activated again according to the specified value. Although the external line of an output is not monitored, a short-circuit will be indicated. Rockwell Automation Publication 1753-IN003C-EN-P - June 2010...
- Page 11 Example: Connecting Actuators to the Outputs Inductive loads can be connected without a protection diode on the load. However, Rockwell Automation strongly recommends that a protection diode be fitted directly to the load to suppress any interference voltage. A 1N4004 diode is recommended.

The next time you cycle power, these settings will be restored to the last values stored into nonvolatile memory. This means that either the settings prior to the reset will be restored, or if any settings were changed after the reset, those new settings will still be in effect.
