Controllers and other devices
Individual devices should be maintained according to the specific
instructions supplied for each device . Remove dust and dirt from
exterior with a dry lint-free cloth . Unless specifically instructed in the
individual device instruction leaflet, do not attempt to open sealed
cases or containers .
WARNING
NEVER USE COMPRESSED AIR TO CLEAN OR BLOW OUT DEBRIS OR DUST
IN RECOMBINERS.
Secondary wiring
Check all wiring connections for tightness and at all terminal blocks .
Check all secondary wiring connections to ensure that they are
properly connected to the Recombiner ground bus, where indicated .
Look for broken wire strands and pinched or damaged insulation .
Ventilation
Check all grills and ventilation ports for obstructions and
accumulations of dirt . Clean ventilation ports, if necessary . For
Recombiners installed outdoors, inspect the air space under the
Recombiner to be sure that it is clean and clear of debris, leaves,
and obstructions .
Records
It is essential to maintain the equipment in satisfactory condition .
Maintain a permanent record of all maintenance activities and
testing for future reference (see
Appendix B
) .
The condition of each Recombiner should be recorded as a guide
for anticipating the need for any replacement parts or components
or special attention at the next regular maintenance period . It is
recommended that a series of inspections be made at quarterly
intervals until the progressive effects of local conditions can be
analyzed to determine a regular schedule .
Recombiner events and service interruptions
Short-circuits and overloads
WARNING
DO NOT ATTEMPT TO RE-ENERGIZE RECOMBINER OVERCURRENT DEVICES
AFTER ELECTRICAL EVENTS, SUCH AS SHORT CIRCUITS, GROUND FAULTS,
AND OVERLOADS, UNTIL THE CAUSE OF THE EVENT HAS BEEN IDENTIFIED
AND CORRECTED.
A thorough assessment, identification, and correction of the
event origin must be completed . An additional assessment of the
conductor insulation and other insulating materials should be made .
Replace all damaged insulation materials, conductors, and over-
current devices . Original Recombiner parts, insulators, insulation
material, and overcurrent devices must be replaced with renewal
parts from Eaton (see “Renewal parts,”
page 12
) .
Do not attempt to re-energize Recombiner overcurrent
components after electrical events, such as short circuits and
overloads, until the cause of the event has been identified
and corrected.
After the event has been rectified, test equipment per the
maintenance process described in this publication .
Physical damage
Any physical damage to the Recombiner that occurs after the
Recombiner is installed must be corrected . A thorough inspection,
which includes the exterior enclosure and deadfront, plus interior
components in the damaged portion of the Recombiner, should be
conducted . Replace all damaged parts and components . Ensure
that there are no gaps in the Recombiner enclosure that could
cause exposure to live parts . Contact Eaton for renewal parts and
assistance .
After the physical damage has been corrected, test equipment per
the maintenance process described in this publication .
Water damage
DANGER
WET RECOMBINERS PRESENT A HAZARDOUS CONDITION AND MAY
CAUSE INJURY OR DEATH. DE-ENERGIZE POWER TO ALL EQUIPMENT
BEFORE SERVICING.
DO NOT WORK ON SURFACES OR FLOORS WHERE THERE IS
STANDING WATER.
DANGER
DO NOT WORK ON RECOMBINERS OR ENTER AREAS THAT HAVE
STANDING WATER. DE-ENERGIZE ALL EQUIPMENT IN AREAS WITH
STANDING WATER.
DO NOT WORK ON WET ENERGIZED ELECTRICAL EQUIPMENT.
Major accumulation
of water or moisture on any part of the
Recombiner can cause catastrophic damage to the Recombiner . If a
Recombiner has been submerged by more than 2 inches or where
running or standing water has had contact with current-carrying
parts, it has sustained significant damage .
WARNING
RECOMBINER COMPONENTS, INCLUDING CIRCUIT BREAKERS, FUSIBLE
SWITCHES, AND SO ON, SUBJECTED TO WATER OR MOISTURE MAY BE
RENDERED UNSAFE. REPLACEMENT IS REQUIRED.
The Recombiner and its components may be damaged beyond
repair and may need replacement .
1. Do not attempt to clean or repair water-damaged equipment
or components.
2. De-energize the Recombiner at its source.
3. Do not energize.
4. Contact Eaton for replacement.
Minor
accumulations
of moisture, such as condensation, over a
short period of time, may be corrected using heat .
De-energize Recombiner .
Apply approximately 250 watts per vertical section for a sufficient
period of time until the moisture disappears, then remove all heat
sources and materials used for drying .
Inspect for damage to components and any corrosion . If any
damage or corrosion is present, contact Eaton . DO NOT
RE-ENERGIZE RECOMBINER .
After the Recombiner has dried completely, remove all materials and
tools from the equipment . Inspect all connections for damage and
torque . Reinstall all covers, fillers, deadfront assemblies, and side
sheets . Conduct Recombiner insulation resistance testing described
in this publication .
