Installation of Benshaw Starter
Once all of the above components are removed, see
Figure 26, p. 27 for the approximate locations of the new
components.
The Benshaw Redistart SSS is supplied with current
tran
sform
ers. 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
Figure 29, p. 31 for proper installation location of the
Be
nshaw current transforme
rs.
Note: Be
nshaw CTs are polarity sensitive. For specific
details on m
ounting of the Benshaw Solid State
Starter, refer to the “Benshaw Solid State Starter
Hardware Manuel” pages 20-32. The manual ships
with the Benshaw starters.
