Connect cables between recloser switch
units and triple-single type SDR controller
1. Connect control cable to the recloser
switch unit poles and triple-single type
SDR controller. The type SDR triple-single
recloser control cable consists of two
parts. The lower cable has a 40-pin
connector on the end that connects to the
type SDR triple-single controller. The end
nearest to the recloser switch units has a
64-pin in-line weatherproof connector.
The upper cable has a mated 64-pin
connector with three leads at least four
feet in length. Each lead is marked with
the phase identification of the
corresponding recloser switch unit pole.
The connection on the control cable is
protected against polarity mismatch.

2. Secure plugs to prevent them from
loosening using the locking clip.
3. Connect voltage sensor cable (optional) to
the recloser switch unit poles and triple-
single type SDR controller. The type SDR
triple-single recloser voltage sensor
consists of two parts. The lower cable has
a 12-pin connector on the end that
connects to the type SDR triple-single
controller. The end nearest the recloser
switch units has a 10-pin in-line
weatherproof connector. The upper cable
has a mated 10-pin connector with three
leads at least four feet in length. Each
lead is marked with the phase
identification of the corresponding
recloser switch unit pole. The connection
on the sensor cable is protected against
polarity mismatch.
