For details about EPI2 actuator the reference
manual is: EPI2 Quarter-turn Electric
Actuator IOM.
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
paragraph 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.
WARNING
It is assumed that the installation, configuration,
commissioning, maintenance and repair works
are carried out by qualified personnel and
checked by responsible specialists.
WARNING
Repair work, other than operations outlined in this
manual, is strictly reserved to qualified Emerson
personnel or to personnel authorized by the
company itself.
2 OPERATION AND STORAGE
The module is designed to work and to be
stored in the same environment of the actuator.
3 DISTINGUISH OLD/NEW MODELS
Figures below allow to distinguish old version
of EPI2/F02 from the new version (on the labels
are underlined the digits of Product Number);
furthermore, the logic boards with heatsink
identifies old version models, while logic boards
without heatsink identifies new version models.
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.

It is important to distinguish between EPI2/F02
old models and the new ones.
To install the board on base actuator, in fact, it
is necessary to choose the correct mechanical
parts form 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 paragraphs.

4 INSTALLATION
To assemble the OM11 into the EPI2/F02
actuator, proceed as follows:
• Ensure that all the parts received with the
OM11 are available as described in paragraph
Optional kits.
• Using paragraph 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 (Figure 5).

• Detect the black cable required for the
OM11 which is already included in the basic
actuator (Figure 7).

• Remove the actuator cover (Figure 6).
Follow one of the following assembling
procedures depending on actuator model.
• Detect the black cable required for the
OM11 which is already included in the basic
actuator (Figure 7).
