Installation procedure
All reclosers are carefully tested and adjusted at the factory.
Well-equipped test facilities, detailed testing procedures,
and thoroughly trained personnel assure accurately
calibrated equipment. Each recloser leaves the factory ready
for installation.
1. Check the data plate ratings. Make sure the ratings
of each recloser data plate are correct for the planned
installation.
2. Perform high-potential withstand tests. Prior to
installing the VSA recloser, with the recloser in the
OPEN position, perform high-potential withstand
tests across each open interrupter assembly. Refer to
the High- Potential Withstand Testing section of this

iMPortaNt
This recloser has four lifting lugs; all must be used when
lifting. Maximum strength is attained with a vertical lift.
Use of a spreader bar, with a fixed attachment point for
the hook at the load center, is recommended when lifting.
If a sling is used for lifting the recloser, it must have a
fixed attachment point at the load center. Rig the recloser
so that the sling height is equal to or greater than the
distance between lugs.
