Connectors
Figure C.5 shows a diagram of a typical installation of the Full-Size Enclosure
model with individual sensor connectors.
Ground Conductor
Ground the SEL-734B Capacitor Bank Control cabinet by using the ground
lug before making any other connections to the cabinet.
Sensor Cables
One measurement cable connects to one combination sensor. For three-phase
sensing, connect all three sensors to the enclosure (see Figure C.5 and
Figure C.3). If sensing only a single phase, install SEL-C530S shorting plugs
into the unused connectors to short them to neutral and minimize noise (see
Figure C.4).
