General Information
Once the type of starter is determined, proceed to the
section in the bulletin that corresponds with the correct
unit and start type.
Important:
Always follow safe electrical practices while
installing the new starter. Be certain to route
new wiring neatly through the starter panel.
Do not allow the wiring to come in contact
with any sharp objects. It is advised to place
fish paper between the bottom of the starter
cabinet and wiring.
Important:
UL REQUIREMENT
•
The field conversion of the starter will void the
factory UL listing.
•
The customer must obtain a UL inspection if a UL
listing is required.
Removal of Existing Starter
See unit chapters for specific information on existing
starter removal.
Installation of Benshaw Starter
See unit chapters for graphics which show unit specific
installation information and location of required
components for the Benshaw RediStart SSS conversion.
Notes:
•
All Benshaw Solid State Starters supplied after
November 2010 are MX2 starters.
•
The Benshaw Redistart SSS is supplied with current
transformers. The current transformers wired to the
chiller need to remain installed as shipped from the
factory. The current transformers supplied with the
solid state starter need to be installed as close to the
original current transformers as possible for proper
operation.
•
See unit specific chapters for the proper installation
location of the Benshaw current transformers.
•
Benshaw CTs are polarity sensitive. For specific details
on mounting of the Benshaw Solid State Starter, see
"Benshaw Solid State Starter Hardware Manual, pages
20-32. The manual ships with the Benshaw starter.
•
Secure locally any required low voltage wire, bolts,
nuts and other hardware as required.

Cabinet Fan (optional)
A locally obtained cabinet fan needs to be installed in the
cabinet to avoid overheating. The fan can be mounted
internal or external to the cabinet. See
part numbers.
Note: The fan can be mounted over the existing vents on
the cabinet. It is not necessary to cut a hole on the
cabinet.
Circuit Breaker and Shunt Trip
Important:
All units that are converted to the Benshaw
RediStart Solid Start Starter REQUIRE a
circuit breaker and shunt trip device.
•
If the unit was built with a circuit breaker, contact Trane
Service Parts for shunt option or source locally.
•
If unit was NOT built with a circuit breaker, one must be
added, as well as the shunt breaker as listed above.
Contact Trane Service Parts for circuit breaker
information.
Refer to local and state electrical codes for proper sizing of
the shunt trip device.
Benshaw Remote Display Panel
The remote display panel is recommended if voltage and
current monitoring is necessary. See
p. 41
for further details.
