Installation Examples
Full-Size Enclosures With Individual Sensor Connectors
The SEL-C530 cable connects to a single Lindsey Manufacturing Co.
combination sensor. The Lindsey 9-587/XX/9-582 cable can be used as an
alternative.
Power Supply/Neutral
Sensor Cable
The power supply/neutral sensor cable connects to the 4-pin military standard
connector on the bottom of the enclosure.
The SEL-C532 cable provides a pigtail to connect to the control power
transformer and a neutral sensor (see Figure C.5 and Figure C.4). The
SEL-C539 cable provides a pigtail to connect to the control power
transformer, and a 4-pin connector to plug into a Lindsey R-Z2981SS cable
and neutral sensor (see Figure C.3).
Control Cable
The control cable connects to the 19-pin connector on the bottom of the
enclosure. Each of the three cable legs connects to a single-phase capacitor
bank switch. Control power is provided through the power supply/neutral
sensor cable, and not the control cable.
The SEL-C531 cable connects to three 5-pin switches, but additionally
supports 526 auxiliary contact monitoring. The SEL-C538 cable connects to
three 6-pin switches and supports 52a and 52b auxiliary contact monitoring.
