WARNING
EPI-2 actuator 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 EPI-2 actuators and all
optional 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 authorized by the company itself.

Manufacturer with respect to Machinery
Directive 98/37: as specified on the EPI-2 label.
1. OPTIONAL MODULE 13: 3-WIRES MODULE
1.1 OM13 module functionality
The OM13 3-wires module is supplied as an
option to the Keystone EPI-2 actuators.
It is possible to receive the actuator already
equipped with the OM13, ordering it with the
basic feature.
Alternatively, it is possible to order the OM13 as
a separate kit and install it in the basic actuator
in the factory or in the field.
The OM13 is an optional module suitable
to accomplish the following EPI-2 actuator
additional functionality:
• 120/240V AC 1-phase, 50/60Hz, 3-wire
control for open/close operations, without
additional power supply.
IMPORTANT
For decommissioning instructions, please refer
to the relevant chapter in the EPI-2 manual ref.
VCIOM-02819.
IMPORTANT
The OM13 command has to be provided by two
separate switches for open and for close with
a delay of at least one second between the two
commands, when reversing the operation from
open to close or vice versa.
VCIOM-01495-EN15/05
Before installation these instructions must be fully read and understood

USE TO AVOID INDUCED VOLTAGE PHENOMENA
Alternatively, to avoid induced voltage phenomena over floating command line, the following wiring diagram may be used.
NOTES
1. Supply from 110 to 240V AC / 1-ph
L2 neutral
When L1 - L2 - L3 cables are long (more than
10metres) induced voltage phenomena may occur
on floating command line.
To avoid this unwanted effect, realize a cabling
system where unused line (either L1 OPEN or
L3CLOSE) is pulled to NEUTRAL line. To do this a
switch may be used.
For example with the BACO PN NC02GQ1 the
following configuration may be used:
short circuit pins 1 and 3
short circuit pins 5 and 7
short circuit pins 2 and 8
short circuit pins 4 and 6
pin 3 = PHASE
pin 5 = NEUTRAL (L2)
pin 2 = OPEN (L1)
pin 4 = CLOSE (L3)

the terminals 33-34
