Section 1: Introduction
Introduction
NOTE:
Before installation, these instructions must be fully read and understood.
Section 1: Introduction
The OM11 DeviceNet interface is an electronic module that allows you to connect the
Keystone EPI2 electrical actuator to a DeviceNet network. The module has its own
microprocessor and acts as a pure bus interface without affecting the actuator control
integrity. It is installed inside the actuator housing and takes the electrical power from the
actuator power supply module. The DeviceNet network is fully isolated from the
actuator electronics.
For details about EPI2 actuator, please refer to Installation, Operation and Maintenance
Manual for Keystone EPI2, Electric Actuator.
!WARNING
EPI2 actuators must be electrically isolated before any disassembling or reassembling
operations. Before any disassembling or reassembling operations, please follow in detail
the relevant section of the basic installation and operating manual (latest revision available).
!WARNING
The electronic parts of the EPI2 actuators and all option modules can be damaged by
a discharge of static electricity. Before you start, touch a grounded metal surface to
discharge any static electricity.

Section 3: Distinguish Old/New Models
It is important to distinguish between EPI2 old models and the new ones. To install the
board on base actuator, in fact, it is necessary to choose the correct mechanical parts from
the kit.
Furthermore, the meaning of some data exchanged on the DeviceNet interface depends
on model (old or new); differences will be explained in the following sections.
Figures 1 and 2 allow to distinguish old version of EPI2 from the new version (on the labels,
the digits of Product Number are boxed); furthermore, the logic boards with heatsink

Installation
Section 4: Installation
Section 4: Installation
To assemble the OM11 into the EPI2 actuator, proceed as follows:
• Ensure that all the parts received with the OM11 are available, as described in
Section 12, Optional Kits.
• Using Section 12, Optional Kits, select only mechanical parts (screws and spacers)
depending on actuator models.
• Gather the right tools for the assembly and for setting the actuator controls.
• With an Allen wrench of 5 mm, unscrew the cover screws, see Figure 5.
Figure 5
• Remove the actuator cover, see Figure 6.
Figure 6
Follow one of the following assembling procedures depending on actuator model.
