4. Ground the recloser. Make the ground connection to
the ground connector. The ground connector is located
on the back of the mechanism housing.
• Refer to Figures 3 and 5 for ground connector loca-
tion. The ground clamp accepts #10 to #2 stranded
cables.
• Refer to Figures 11, 12, and 13 for recommended
grounding for the Type NOVA recloser.
5. Install the control. Refer to the control installation
manual and install the control. Make sure the control
cable is connected between the control and the reclos-
er, the control is properly programmed for the planned
installation, and the control is grounded.
Control-powered NOVA reclosers manufactured after
September 2004 require a Voltage Trip/Close (VTC)
interface and a VTC-ready control for tripping and
closing. This VTC requirement applies to three-phase,
control-powered NOVA reclosers with a Type A or
Type D mechanism with serial numbers 100,000 and
above or beginning with the characters CP57. They
can be identified by labels prominently displayed on
the bottom of the recloser tank and on the side near
the 19-pin receptacle, as shown in Figure 8. Control-
powered NOVA reclosers with serial numbers below
100,000 do not require a VTC-ready control. Refer to
the recloser nameplate for the serial number.
