seismic certification of motorpact medium voltage (mv) motor controllers
Motorpact MV motor controllers that are seismically certified have been qualified
for the site-specific seismic requirements of the listed model building codes and
standards. Optional construction features may be required, depending on the
location of the installation and the particular code and standard of interest.
Seismic certificates of compliance and equipment labels are provided with all
seismically certified equipment. To maintain the validity of this certification, the
installation instructions provided in this bulletin must be followed.
responsibility for
mitigation of seismic
damage
For the purposes of the model building codes, Motorpact MV motor controllers are
considered nonstructural building components. Equipment capacity was
determined from tri-axial seismic shake table test results as defined in the
International Code Counsel Evaluation Service (ICC ES) Acceptance Criteria for
Seismic Qualification Testing of Nonstructural Components (AC156). Unless
otherwise indicated, an equipment importance factor of 1.5 (IP = 1.5) was used,
indicating that equipment functionality was verified before and after shaker table
seismic simulation testing. This importance factor is indicative of critical facilities
where maximizing the probability of post event functionality is a priority. AC156 is
published by the ICC ES and has been recognized by the Building Seismic Safety
Council (BSSC) as an appropriate methodology in the 2003 National Earthquake
Hazard Reduction Program (NEHRP) Commentary (FEMA 450 Part 2). The
National Institute of Building Sciences established the BSSC in 1979 to develop and
promote regulatory provisions for earthquake risk mitigation at the national level.
Incoming and outgoing cable and conduit must also be considered as related but
independent systems. They must be designed and restrained to withstand the
forces generated by the seismic event without increasing the load transferred to
the equipment. For applications where seismic hazard exists, bottom entry and
exit of cable and conduit is preferred. If the spectral acceleration value (Ss as
defined by the International Building Code or NFPA 5000) is in excess of 2.67g
(such as the New Madrid seismic area), then the equipment must also be braced
at the top using a lateral restraint system. A lateral restraint system is required in
situations where horizontal motion at the top of the equipment is not be desirable
(such as applications where top entry and exit of conduit are used). This system
must be capable of transferring the loads created to the load-bearing path of the
building structural system.
maintaining seismic
certification
Schneider Electric’s seismic qualification of nonstructural components is just one link
in the chain of responsibility required to maximize the probability that the equipment
will be intact and functional after a seismic event. During a seismic event, the
equipment must be able to transfer the loads that are created through the mounting
pad and anchorage to the loadbearing path of the building structural system.
The structural civil engineer or consulting engineer of record is responsible for
detailing the equipment connection and anchorage requirements (including the
lateral restraint system, if appropriate) for the given installation. The installer and
manufacturers of the anchorage and lateral restraint system are responsible for
assuring that the mounting requirements are met. Schneider Electric is not
responsible for the specification and performance of these systems.

Avoid sharp turns, corners, and edges that could damage or
weaken the cable insulation. Follow the cable manufacturers
instructions to determine the minimum bending radius of cables.
It is highly recommended to insure cables do not come in contact
with metal parts or opposite phases.
Failure to follow this instruction will increase the electrical stress on the
cable, shortening the life of the equipment.
cable installation
Cables must be securely fastened or braced to withstand short circuit forces and
to prevent strain on the terminals.
Maximum length of unsupported cable is 457 mm for line side cable and 1100 mm
for load side cable.
connecting cables
Before making cable connections, check to see if special site preparation
requirements are needed. Determine the phase identity of each cable. Viewing
the controller from the front, standard busbar sequence is normally phased L1–
L2–L3 left to right and L3–L2–L1 top to bottom and front to rear, unless labeled
otherwise.

Restrict entry into the area to prevent any unauthorized
personnel from approaching the gear during testing.
■
Notify all persons that the test is going to be conducted.
■
Follow all local lockout and tag-out procedures.
■
Remove all fuses—low voltage and medium voltage.
■
Disconnect surge arresters, surge capacitors, and power factor
correction capacitors (if supplied).
NOTE: Do not use cable earthing switch (if supplied) to discharge
capacitors.
WARNING
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
If load is a capacitor bank, wait 5 minutes before servicing equipment.
Capacitors should have an internal resistor to dissipate voltage to 50 V
maximum after 5 minutes.
Failure to follow this instruction can result in death or serious injury.
Schneider Electric
■
Disconnect or earth capacitive dividers, if supplied.
■
Unearth or OPEN the cable earthing switch, if supplied. For
operation procedures, see “cable earthing switch operation”
in the instructions for use guide.
■
All earth connections must be properly made and tightened.

After completing hi–pot testing, temporarily earth the busbars to
remove any residual charges.
Failure to follow this instruction can result in injury.
phase-to-phase hi-pot testing
Follow these steps to perform a phase-to-phase hi-pot test:
■
Perform a phase-to-phase hi-pot test on the main busbar.
— Gradually increase the voltage to the test levels of the
standards in force.
— Verify that the equipment sustains the required voltage
without flashover for one minute.
■
phase-to-ground hi-pot testing
Turn off the test equipment. Discharge to earth the phase
busbar before removing the test cables.
Follow these steps to perform a phase-to-ground hi-pot test:
■
Perform a phase-to-earth hi-pot test on the main busbar.
— Gradually increase the voltage to the levels shown in the test
levels of the standards in force.
— Verify that the equipment sustains the required voltage
without flashover for one minute.
■
Turn off the test equipment. Discharge to earth the phase
busbar before removing the test cables.
If the test is unsuccessful, inspect the insulators for leakage paths. If
necessary, clean the surface of the insulator(s) with denatured alcohol and
re-test. If problems persist, DO NOT ENERGIZE THE EQUIPMENT.
Contact your local field sales office or your distributor.
If the equipment has been stored for several months or has been exposed
to high humidity during the storage time period, PERFORM A STANDARD
HI–POT (DIELECTRIC) TEST. First energize the heater circuits for a
minimum of 24 hours. Follow other equipment testing procedures as
required by customer in-house standards.

tightening torque.
‰ Verify that all protective relays have been configured with
proper settings per the outcome of customer’s coordination
study.
‰ Verify that all insulating surfaces, including the primary support
insulators and isolation barriers, are clean and dry.
‰ Verify that all primary fuses are installed and orientated
properly and do not exceed the nameplate rating for their
cubicles. see "installing fuses" in the instructions for use
guide.
‰ Verify all surge arresters, surge capacitors, and power factor
correction capacitors are connected. see "standard
tightening torques."
‰ Before energizing any source of electric power, make a final
check of the equipment. Inspect every compartment for loose
parts, tools, litter, and miscellaneous construction items.
