See Figure 20, p. 21
components.
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.
Note: Benshaw CTs are polarity sensitive. For specific
details on mounting 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.
