Make sure the ratings,settings, and interface options on each recloserdata plate (see Figure 2) are correct for the plannedinstallation.Figure 2 NOVA STS recloser data plate2. Perform high-potential withstand tests. Prior toinstalling the NOVA STS recloser, perform high-potentialwithstand tests. Refer to the Service informationsection for high-potential withstand test procedures.This test will help identify any shipping damageaffecting the dielectric condition of the recloser or thevacuum integrity of the interrupter.CAUTIONPersonal injury Sheds on epoxy encapsulation havesharp edges Wear protective gloves when handling theunit Failure to do so can result in cuts and abrasionsT258 13.
