1. PRODUCT REVISION HISTORY

The following information provides an historical summary of changes made to this product since the
original release.

Operating & Service Manual Version

Contact Thomson Power Systems, to obtain applicable instruction manuals or if in doubt about any
matter relating to installation, operation or maintenance. Soft copy of the most current version is
available at www.thomsontechnology.com.

NOTE: All information contained in this manual is for reference only and is subject

to change without notice.

1.1. ENVIRONMENTAL CONDITIONS

CAUTION!!!

Failure to store and operate equipment under the specified environmental conditions may
cause equipment damage and void warranty.

1.1.1. EQUIPMENT STORAGE

The transfer switch shall be stored in an environment with a temperature range not
exceeding -4° to +158° Fahrenheit (-20° to +70° Celsius) and a humidity range not
exceeding 5%-95% non-condensing. Before storing, unpack sufficiently to check for
concealed damage. If concealed damage is found, notify the ATS supplier and the
Carrier immediately. Repack with the original, or equivalent packing materials. Protect
from physical damage. Do not stack. Store indoors in a clean, dry, well ventilated

area free of corrosive agents including fumes, salt and concrete/cement dust. Apply
heat as necessary to prevent condensation.

1.1.2. EQUIPMENT OPERATING

The transfer switch shall be operated in an environment with a temperature range not
exceeding +5° to +122° Fahrenheit (-15° to +50° Celsius) and a humidity range not
exceeding 5%-95% non-condensing.

2. NOTES TO INSTALLER

Arc Flash and Shock Hazard. Will cause severe injury or death.

Do not open equipment until ALL power sources are disconnected

This equipment must be installed and serviced only by qualified electrical

DANGER!!!!

personnel utilizing safe work practices and appropriate Personal Protective
Equipment (PPE). Failure to do so may cause personal injury or death

2.1. ELECTRICAL CONNECTIONS

To ensure satisfactory installation of this equipment be sure to observe "Cable Terminal
Information” regarding power cable connection tightness located in this manual.

All mechanical and electrical connections must be checked for tightness prior to placing this
equipment in service to ensure proper operation and to validate applicable warranty
coverage.

2.2. TRANSFER SWITCHES WITH ADJUSTABLE OVER CURRENT
PROTECTION

Standard models of automatic transfer switches incorporate integral over current protection.
Transfer switches rated 1000A or higher are supplied with adjustable over current protection
trip units. For models of transfer switch with integral over current protection, the over current
protection must be set prior to operation. The equipment will be shipped from the factory
with a long-time current setting of 100% (of the equipment rating) and maximum short­time/instantaneous current and time delay settings.

PM059 REV 9 14/01/16 2 Thomson Power Systems

WARNING!

TS 830 TRANSFER SWITCH

Do Not Energize this equipment until
device settings have been verified to
ensure proper system protection &
coordination. Failure to do so may
result in equipment failure.

Refer to Section 5.1.3 of this manual for additional information on operation of the Transfer
switch following an over current trip condition.

Refer to information supplied with the transfer switch documentation package for adjustment
procedures on the power switching units over current protection trip unit. Contact the factory
if any additional information is required.

2.3. TRANSFER SWITCHES WITH MULTI-TAP VOLTAGE CAPABILITY

If the transfer switch has programmable multi-tap voltage capability confirm the transfer
switch has been configured for the correct system voltage prior to installation.

WARNING!

Failure to confirm and match transfer
switch voltage with the system voltage
could cause serious equipment damage.

The voltage selections and connections are shown on the engineered drawings attached to
each transfer switch. The factory default settings will be indicated on the calibration label
attached on the inside of the enclosure door (supplied loose on open style models). A blank
label is included to record the applicable settings if the configuration is changed from the
factory default settings.
To change the transfer switch configuration the following must be accomplished:

 Change voltage taps on potential transformers (PT’s) to correct system voltage (refer

to drawings)

 Change program setting in the applicable controller used on the transfer switch (e.g.

TSC 80E, MEC 310) for nominal system voltage. Refer to the applicable controller
instruction manual for further information.

 Once the PT voltage taps and controller has been re-programmed to correct

operating voltage, the “control circuit isolation plug” on the mechanism, may be

reconnected, prior to voltage energization.

conductors must have the correct phasing as shown below.

WARNING!

Failure to match correct system phasing
will result in serious damage to the
controller.
