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.
1.3.3. REMOTE START CONTACT FIELD WIRING
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 panel should conform to the following guidelines to
avoid possible controller malfunction and/or damage.
1.3.3.1.Minimum #14 AWG (2.5mm
2
) wire size shall be used for distances up to
100ft (30m)
1
). For distances exceeding 100 ft. (30m) consult Thomson
Technology.
1.3.3.2.Remote start contact wires should be run in a separate conduit.
1.3.3.3.Avoid wiring near AC power cables to prevent pick-up of induced
voltages.
1.3.3.4.An interposing relay may be required if field-wiring distance is
excessively long (i.e. greater than 100 feet (30m)) and/or if a remote
contact has a resistance of greater than 5.0 ohms.
1.3.3.5.The remote start contact provided is voltage free (i.e. dry contact).
Refer to the “TSC 80e Typical Connection Diagram” on page 52 for
terminal interface and contact voltage/current ratings or page 13 for
specifications on output contact ratings. Applying voltage or current in
excess of the ratings will damage the controller and is not cover by
Thomson Technology’s limited warranty.
1.3.4. DIELECTRIC TESTING
Do not perform any high voltage dielectric testing on the transfer switch with the
TSC80e controller connected into the circuit, as serious damage will occur to the
controller. All AC control fuses and control circuit isolation plugs connected to the
TSC80e must be removed if high voltage dielectric testing is performed on the transfer
switch.
