3. NOTES TO INSTALLER

Before opening the transfer switch enclosure to perform any service task, or to manually transfer the

mechanism, it is imperative to isolate the transfer switch from any possible source of power. Failure

to do so may result in serious personal injury or death due to electrical shock.

CAUTION!!!

All installation and/or service work performed must be done by qualified

personnel only. Failure to do so may cause personal injury or death.

3.1. 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.

3.2. 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 short-

time/instantaneous current and time delay settings.

WARNING!

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.

PM059 REV 6 08/05/05 2 Thomson Technology

TS 830 TRANSFER SWITCH

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.

3.3. 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 80, TSC 800, MEC 2, MEC 20, 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.

3.4. SYSTEM PHASING-HIGH LEG DELTA SYSTEMS

For systems using high leg delta 240V 3 phase 4 wire systems, connection of supply

conductors must have the correct phasing as shown below.

WARNING!

Failure to match correct system phasing

will result in serious damage to the

controller.

CAUTION!!!

All installation and/or service work performed must be done by qualified

personnel only. Failure to do so may cause personal injury or death.

Where transfer switches are supplied without power isolation transformers (PT1 &

PT2) for ATS control logic it is essential that the orientation of phase conductors of

the supply source be arranged such that the phase of highest potential with respect

to ground is not connected to the power supply inputs to the controller (The A Phase

for both supplies). Failure to do so will result in equipment damage.

Per NEC Article 384-3 (f) “The B phase shall be that phase having the higher voltage

to ground on a 3-phase, 4-wire delta connected systems.”

3.5. REMOTE START CONTACT FIELD WIRING

For applications using TSC 80, 800 controllers, as a minimum, the remote engine

start control field wiring shall conform to the local regulatory authority on electrical

installations. Field wiring of a remote start contact from a transfer switch to a control

PM059 REV 6 08/05/05 4 Thomson Technology

TS 830 TRANSFER SWITCH

panel should conform to the following guidelines to avoid possible controller

malfunction and/or damage.

3.5.1. Minimum #14 AWG (2.5mm2) wire size shall be used for distances up to 500ft

(150m)1). For distances exceeding 500 ft. (150m) consult Thomson

Technology.

3.5.2. Remote start contact wires should be run in a separate conduit.

3.5.3. Avoid wiring near AC power cables to prevent pick-up of induced voltages.

3.5.4. An interposing relay may be required if field-wiring distance is excessively

long (i.e. greater than 500 feet (150m) and/or if a remote contact has a

resistance of greater than 5.0 ohms.

3.5.5. The remote start contact must be voltage free (i.e. dry contact). The use of a

“powered” contact will damage the transfer controller.

3.6. DIELECTRIC TESTING

Do not perform any high voltage dielectric testing on the transfer switch with the

controller connected into the circuit, as serious damage will occur to the controller.

All AC control fuses and/or control circuit breakers or control circuit isolation plugs

connected to the controller must be removed if high voltage dielectric testing is

performed on the transfer switch.

3.7. INSTALLATION OF OPEN TYPE TRANSFER SWITCHES

Please contact Thomson Technology for additional information.

4. GENERAL DESCRIPTION

Thomson Technology TS 830 series of Automatic Transfer Switches employ two mechanically

interlocked enclosed contact power switching units and a microprocessor based controller to

automatically transfer system load to a generator supply in the event of a utility supply failure.

System load is then automatically re-transferred back to the utility supply following restoration of the

utility power source to within normal operating limits. Transfer switches with MEC 2, MEC 20 or

MEC 310 controllers installed have integral engine-genset auto start control & monitoring features

and therefore these applications do not require an engine-mounted auto start control panel.

The standard TS 830 series Automatic Transfer Switch is rated for 100% system load and does not

require upstream over current protection. Refer to Section 6 of this manual for detailed information

on over current protection.
