Service Requirements
The Type NOVA recloser has been designed with a
minimum mechanical life of 10,000 operations. The NOVA
recloser should be inspected every ten years to check for
physical damage and verify proper operation.
Frequency of Inspection
Because these reclosers are applied under widely vary-
ing operating and climatic conditions, service intervals are
best determined by the user based on actual operating
experience. However, solid-insulated, vacuum-interrupting
reclosers should be inspected every ten years.
Testing Operation
This recloser is used with Cooper Power Systems micro-
processor-based recloser controls. Refer to the control
operation manual.
1. Check the data plate ratings. Make sure the rat-
ings, settings, and interface options on the recloser
data plate (Figure 14 and Table 7) are correct for the
planned testing.
2. Test electrical open and close operation. Close and
open the recloser contacts using the microprocessor
control. Confirm that the contacts have closed and
opened by:
A. The OPEN/CLOSE contact position indicator, or
B. By a continuity check between the recloser
terminals.
3. Test manual open. Pull the yellow manual open
handle (Figure 14) down to open the recloser contacts.
Confirm that the contacts have opened by:
A. The OPEN/CLOSE contact position indicator
OR
B. By a continuity check between the recloser
terminals.
4. To close the recloser contacts:
A. First, push the yellow manual open handle up.
B. Close the recloser using the microprocessor-
based control.
Note: When manual close and open operations are being per-
formed from the control front panel, it is recommended
to wait 60 seconds after every fourth close/open opera-
tion. This recommendation also applies if conducting four
operations with fault current applied to the unit.
