EQUIPMENT STORAGE
The following procedures are required for correct storage of the transfer switch prior to installation.

CAUTION!!!
Failure to store equipment as specified may cause damage and void warranty
.


Before storing, unpack sufficiently to check for concealed damage. If concealed damage is
found, notify Thomson Technology and the Carrier immediately.
Repack with the original, or equivalent packing materials. Protect from physical damage. Do
not stack.
Store indoor 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.

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.

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 (PTs) 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. TS 830 TRANSFER SWITCH

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 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 (2.5mm
2
) 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 t
