Storage
If it is necessary to store the contactor before it is put into service, be certain to
store it in a clean, dry, dust- and condensation-free area. Do not store contactor
outdoors.
Storage temperature should be maintained between -20°C to 65°C (-4°F to 149°F).
If storage temperature fluctuates or if humidity exceeds 85%, space heaters
should be used to prevent condensation.
Vacuum Bottle Integrity Test
The internal dielectric condition and vacuum integrity of the vacuum bottles is
determined by this test.
Power Frequency Dielectric Tests for new dry equipment are defined in Clause
8.9 of NEMA ICS 3-2 and Clause 8.4 of ICS1. Periodic field testing (every
50,000 operations, or annually, whichever occurs first) will ensure that vacuum
bottle integrity exists. The tests are to be performed as shown in Table 2.A.
Do not apply a voltage higher than 25,000 volts across the
open contacts of a vacuum bottle. Dangerous x-ray
emissions may be produced.
Vacuum bottles are thoroughly tested at the factory;
however, mishandling during shipment may cause damage.
It is very important to perform the vacuum bottle integrity
test before energizing the contactor for the first time, and
before it is returned to service after maintenance or repair;
otherwise perform the test annually. Failure to perform this
test may result in personal injury or damage to the
equipment if the vacuum bottle integrity fails.
High voltage testing is potentially hazardous. Use caution
when performing the Hi-pot test. Failure to do so may result
in severe burns, injury or death.
