Sync Control for Eaton 9395P and 93PM 4
User’s and Installation Guide
1Introduction
The Eaton® Sync Control maintains the critical load outputs of two separate Eaton UPS systems
in synchronization. Use of the Eaton Sync Control provides the uninterrupted transfer of the load
from one load bus to another by means of downstream, dual-source, static transfer switches.
Without the load sync option, the two system output (critical load) buses could become out of
phase with each other. This condition occurs if suitable bypass sources are not available or if the
bypass sources feeding each system are not in sync with each other. Examples of this condition
are two systems supplied by separate diesel generator sets, or the bypass sources for the two
systems are lost.
The Eaton Sync Control can provide customer remote monitoring of sync control operation and
alarms. See paragraph 4.4 for detailed information.
Figure 1-1 shows the front view and Figure 1-2 shows the interior view of the Eaton Sync
Control.

information:
RISK OF ELECRICAL SHOCK – Indicates that a risk of electric shock is present and the
associated warning should be observed.
CAUTION: REFER TO OPERATOR’S MANUAL - Refer to your operator’s manual for
additional information, such as important operating and maintenance instructions.
This symbol indicates that you should not discard the UPS or the UPS batteries in the
trash. This product contains sealed, lead-acid batteries and must be disposed of
properly. For more information, contact your local recycling/reuse or hazardous waste

2Installation Plan and Unpacking
The Eaton Sync Control is shipped as a separate item and can be mounted on any surface that
can safely bear its weight. See paragraph 2.2 for weight, dimensions, and wiring preparation.
2.1 Creating an Installation Plan
Before installing the UPS system, read and understand how this manual applies to the system
being installed. Use the procedures and illustrations in the following chapters to create a logical
plan for installing the system.
NOTE
Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified on page 33 become void. This service is
offered as part of the sales contract for the UPS. Contact service in advance (usually a
two week notice is required) to reserve a preferred startup date.
2.2 Preparing the Site
For the Eaton Sync Control to operate at peak efficiency, the installation site must meet the
environmental parameters outlined in the applicable Eaton 9395P or Eaton 93PM User’s and
Installation Guide that are listed in paragraph 1.3 on page 7.
2.2.1. Environmental and Installation Considerations
The life of the Eaton Sync Control is adversely affected if the system is not installed in a
temperature and humidity controlled indoor area free of conductive contaminants.
Failure to follow guidelines may void your warranty.
Attach the Eaton Sync Control to the wall with appropriate fasteners and washers. The Eaton
Sync Control includes 4 x 8mm mounting holes as shown in Figure 2-1. As wall materials vary,
fasteners for fixing to the wall are not included.
The equipment operating environment must meet the weight requirements shown in Table 2-1
and the size requirements shown in Figure 2-1 and Figure 2-2. Dimensions are in millimeters
(inches).

2.2.2. Eaton Sync Control Wiring Preparation
Read and understand the following notes while planning and performing the installation:
•Refer to national and local electrical codes for acceptable external wiring practices.
•Material and labour for external wiring requirements are to be provided by designated
personnel.
•For external wiring, use 70°C copper wire with a minimum insulation rating of 400V. If wire
is run in an ambient temperature greater than 30°C, higher temperature wire and/or larger
size wire may be necessary. See the applicable wiring information in Chapter 3.1 for the
Eaton 9395P and in Chapter 3.2 for the Eaton 93PM UPS.
•Use wiring with a minimum insulation rating of 400V for interconnections between the Eaton
Sync Control, the UPS, and the customer remote monitoring system.
•Sync Control dry contacts are rated at 5–30 VDC/250 VAC at 2A per contact (maximum load).
•When installing external wiring between the Eaton Sync Control and the UPS, run cables
separate from any power cables to minimize risk for inducted noise to the control signals.
•The Eaton Sync Control can be installed up to a maximum of 150 m (500 ft) from the Eaton
9395P or 93PM UPS system.
CAUTION
When connecting the bypass and load voltage from another model UPS to a Eaton 9395P
or 93PM UPS using the Eaton Sync Control accessory, connect all three phases from the
other UPS to the Sync Control connection point. DO NOT connect the other model UPS
Neutral to the Sync Control connection point when connecting to a Eaton 9395P or 93PM
UPS.
2.3 Inspecting and Unpacking the Eaton Sync Control
The unit arrives covered with protective packaging material.
1. Carefully inspect the outer packaging for evidence of damage during transit.
CAUTION
Do not install a damaged cabinet. Report any damage to the carrier and contact your
Eaton service representative immediately.
2. Remove the protective cardboard covering from the Eaton Sync Control by cutting where
indicated using a knife blade no longer than 25 mm (1”).
3. Remove the plastic bag and foam packing material, and discard or recycle them in a
responsible manner.

3Eaton Sync Control Installation
WARNING
•
Only qualified service personnel (such as a licensed electrician) shall perform the
electrical installation. Risk of electrical shock.
•Shut down all sources of power to the Eaton UPS system before connecting the
control wiring to the Eaton Sync Control enclosure and UPS. Hazardous voltages
exist inside the UPS and in the Eaton Sync Control enclosure. Check all terminal
conductors with a known serviceable voltmeter before connecting the wiring.
When the Eaton Sync Control has been moved to its installed location, unpacked, and inspected,
it is ready for installation and wiring.
Use the applicable procedure from the following list to install the Eaton Sync Control to the UPS:
•� With an Eaton 9395P UPS, proceed to paragraph 3.1.
•� With an Eaton 93PM UPS, proceed to paragraph 3.2.
3.1 Installation and Wiring with an Eaton 9395P UPS

NOTES:
1. Voltage taken from UPS System input switchgear through N.O. aux contacts of UPS
input (bypass) feeders.
2. Voltage taken from UPS System output switchgear, system common output.
3. Connection point in each UPS of a parallel system. Signals can be daisy-chained from
one UPS to next.
4. If Building Alarm 1 is being used for another purpose, any unused building alarm on
the UPS Signal Inputs can be used for the Sync Control. Refer to the applicable Eaton
93PM UPS User’s and Installation Guide for the UPS Signal Inputs.
