Receiving, Handling, and Storage

This section contains instructions for receiving, handling, and storing SureSeT metal-clad indoor switchgear and devices. Follow all safety precautions before working on the equipment.

Receiving

SureSeT two-high, 5/15 kV, metal-clad, indoor switchgear is shipped on pallets in protective crates or wrapping. Circuit breakers are shipped in the switchgear, or separately in protective crates on pallets. Do not stack the circuit breakers. Circuit breakers shipped on pallets have crush cones attached to the top of the circuit breaker box on the pallet. If the cone is crushed, DO NOT accept or use the circuit breaker and report as potential shipping damage to the freight carrier.

Upon receipt, compare the packing list to the equipment received to make sure the order and shipment are complete. Claims for shortages or errors must be made in writing to Schneider Electric within 60 days of delivery. Failure to give such notice will constitute unqualified acceptance and a waiver of all such claims by the purchaser.

Immediately inspect the equipment for any damage that may have occurred in transit. If damage is found or suspected, file a claim with the carrier immediately and notify Schneider Electric. Delivery of equipment to a carrier at any of the Schneider Electric plants or other shipping point constitutes delivery to the purchaser regardless of freight payment and title. All risk of loss or damage passes to the purchaser at that time.

Equipment with Packaging

Handling

The switchgear is normally shipped with one or two sections assembled together as a shipping group. A shipping split is the end of a shipping group which will connect with another shipping group. Each shipping group has four angled lifting lug pad eyes bolted onto the top. If more than two sections are shipped as one shipping group, lifting channels spanning the entire shipping group are bolted on top instead of lifting lugs. To lift and move a shipping group, follow these steps:

  1. Attach a crane hook to each of the four lifting lugs or to the hole in each end of the lifting channels.

    • Use load-rated cables or chains with safety hooks or shackles.

    • A load-rated spreader bar may be necessary to maintain proper angles for lifting.

    • To avoid structural damage, rig the lifting sling so that the minimum angle between lifting cables or chains and the top of the equipment is 45°, and the maximum interior angle is 90°. See the figure Switchgear Lifting Sling.

    • If a crane is not available, contact Schneider Electric before using any other lifting method.

  2. After the equipment has been placed in position, the lifting eyes can be left in place or removed and discarded (if desired).

  3. If removed, install the mounting bolts back into place to cover the mounting holes.

NOTE: If a crane is not available, the shipping group may be unloaded and moved with a forklift. Rollers under the pallet may be used on a relatively flat surface if other moving equipment is not available or space prohibits the use of other moving methods. See Site Selection and Preparation for handling uncrated assemblies.
NOTICE
equipment distortion
  • Do not remove the pallet(s) until all shipping groups are in the final location.
  • Do not maneuver the switchgear directly on rollers.
  • Always have the pallets in place when moving the switchgear.
Failure to follow these instructions can result in equipment damage.

Non—Recommended Moving Methods

CAUTION
falling or dropped equipment
  • If moving by crane, the interior angle of the lifting sling should not exceed 90°. Angles greater than 90° apply greater inward pressure of lifting lugs which can damage or dislodge lifting lugs from switchgear.
Failure to follow these instructions can result in injury or equipment damage.

Storage

Moisture Contamination Avoidance and Mitigation

Shipping, Receiving, and Storage Requirements

This equipment does not achieve its ratings until it is installed per record/as-built drawings, installed per the instructions contained in this document, and has operational environmental controls with appropriate settings to help mitigate environmental influences. This equipment can also be stored in a climate controlled area that uses both heating and cooling to maintain acceptable environmental conditions. Indoor and outdoor rated equipment is not suitable for outdoor storage.

  • The equipment should be treated as if it is in storage until it is installed and operational. The storage area should be clean, dry (75% or less relative humidity), and climate controlled with proper ventilation.

  • To keep the equipment dry, the use of heaters is required in some cases (for example, during seasonal or low periods of loading and equipment de-energization).

    • Consult the Engineer of Record for the appropriate environmental control settings or means to mitigate environmental influences.

    • If so equipped, ensure that the thermostats and/or humidistats are set to mitigate condensation. A minimum of 200 watts of heat per section is suggested.

    • If heaters are being used with the equipment that were not included in the equipment by Schneider Electric, they must be clean and free of debris and grease. Greasy and/or smoky heaters can contaminate electrical insulation and lead to dielectric breakdown and/or tracking.

  • Shipping packaging is not suitable for and cannot be used by itself for equipment storage unless otherwise indicated on the shipping packaging labeling.

  • When receiving equipment, the equipment may be at a lower temperature than the ambient air temperature. Allow time for the equipment temperature, including the temperature of internal components, to rise to ambient air temperatures before making openings in or otherwise or disturbing the packaging. Condensation can occur on and inside the equipment if warm air contacts cold surfaces of the equipment. Moisture damage can occur, destroying the dielectric capabilities of the equipment and rendering it unusable.

  • The factory shipping wrap around the equipment on shipping pallets is not suitable for non-enclosed over the road transportation that risks exposing the equipment to the elements. The factory shipping wrap around the equipment should remain on the equipment until the equipment is ready to be inspected and stored or inspected and installed. After receiving the equipment and allowing it to acclimate to the environment, remove the packaging and inspect the equipment for damage that may have occurred in transit. If damage is found or suspected, immediately file a claim with the carrier and notify the local Schneider Electric representative.

  • Follow these guidelines every time the equipment is moved to a new storage location or to its final destination.

Installation, Operation, and Maintenance Requirements

This equipment does not achieve its ratings until it is installed per record/as-built drawings, installed per the instructions contained in this document, and has operational environmental controls with appropriate settings to help mitigate environmental influences. This equipment can also be operated in a climate controlled area that uses both heating and cooling to maintain acceptable environmental conditions. Indoor and outdoor rated equipment is not suitable for outdoor storage.

In some cases (such as seasonal electrical loading, de-energized equipment, and standby/alternate power sources), the heat generated by equipment loading is insufficient to prevent condensation and alternate heat sources are required. If environmental controls such as a thermostat or humidistat are used, ensure their settings are sufficient to mitigate condensation and remain operational at all times. Consult the Engineer of Record for the appropriate environmental control settings.

Exposure to Moisture and Chemicals

If liquids such as moisture, chemicals, and condensation contact the electronics, circuit breaker, fuses, bussing, or other electrical components, do not attempt to clean or repair the equipment as this may lead to unrepairable damage. If the equipment is energized, de-energize it. If equipment is not energized, do not energize it. Contact the Schneider Electric Customer Care Center at 888-778-2733.

General Storage Requirements

Store the equipment in the original packaging, placed indoors on dry ground or on material that insulates it from humidity.

Recommended Indoor Storage Conditions

Ideal Conditions

Allowable Conditions

Average Relative Humidity For Storage

Measured over a 24-hour period ≤ 95%

If space heaters are furnished in the equipment, energize the space heaters from an external source. To energize space heaters furnished in the equipment, refer to the schematic and wiring diagrams for a logical connection point and for voltage and power requirements.

If the space heaters are normally energized from the CPT in the switchgear, then to energize the space heaters with an external source during storage, follow these steps before connecting the external source.

  1. Open the CPT secondary circuit breaker.

  2. Remove the primary current-limiting fuses.

  3. Install an out-of-service tag, at a suitable location, to clearly indicate the CPT has been rendered out-of-service and to instruct electrical personnel to re-install the current-limiting fuses before installing the switchgear.

These actions open the circuit to the CPT to keep the circuit from back-feeding the CPT and, in turn, the main bus.

Observe the following precautions with the switchgear (see the figure Switchgear Precautions):

  1. Do not place anything on the cubicle.

  2. Do not step or walk on the cubicle.

  3. Do not stack a cubicle on top of another one.

Switchgear Precautions

If the equipment was stored:

  • Between 6 and 12 months, perform basic level preventive maintenance to help ensure correct equipment, circuit breaker, and auxiliary drawer operation.

  • Beyond 12 months, contact the local Schneider Electric Service representative for check-up.

After unpacking, check the equipment carefully for:

  • Absence of broken or damaged parts

  • Absence of condensation marks or droplets

  • Absence of visible degradation (color change, rust, deposits, etc.). In case of any degradation detected, the equipment can not be installed.

If any of the above are discovered, do not install the equipment and contact the local Schneider Electric Service representative.
