Starter Power Leads
The power leads traveling from the incoming power lines
to the solid state starter panel and then from the solid state
starter panel to the compressor motor terminals can be
obtained locally or ordered from Trane Service Parts.
Two wiring kits are necessary for eac
h unit.
Circuit Breaker with Shunt Trip
The Benshaw solid state starter requires a shunt trip circuit
breaker. If the existing starter has a circuit breaker without
a shunt trip device, either a shunt trip element needs to be
added to the circuit breaker or the circuit breaker needs to
be upgraded to include a shunt trip device. The addition of
the shunt trip circuit breaker/device may require some
mechanical modifications to the cabinet.
Additional Components
Some additional components are necessary for proper
operation. Refer to each specific unit section to determine
which additional components are necessary.
Note: Secure locally
any required low vo
ltage wire, bolts,
nuts and other hardware as required.
Service Components
In the event of an MX logic module failure, the MX logic
module is NO LONGER AVAILABLE. See Table 9 for
information
on MX-to-MX2 logic module conversion.
Production Change
All units ordered with a solid state starter after February
2005 were manufactured with the Benshaw Redistart Solid
State Starter.
