Receiving, Handling, and Storage

This equipment is not suitable for outdoor exposure until the equipment is installed per the drawings and instructions contained in this document and has operational environmental controls with appropriate settings.

• Treat the equipment as if it is in storage until it is installed and operational.

• Heaters and other environmental controls may be necessary until the equipment is fully operational. Set the environmental controls (thermostat, humidistat, or other items) to mitigate condensation (including times when the equipment is lightly loaded, such as storage, downstream loads deenergized). Consult the engineer of record for the appropriate environmental control settings.

• The factory shipping wrap around the equipment on shipping pallets is not suitable for over the road transportation without additional protection (such as covering with a tarp). Contact your local Schneider Electric representative in those cases.

• When receiving equipment, where the equipment may be at a lower temperature than the ambient air temperature, allow time for the equipment to rise to ambient air temperatures before making openings in the packaging or otherwise disturbing the packaging. Condensation can occur on and inside the equipment if warm air contacts cold surfaces. Moisture damage can occur destroying the dielectric capabilities of the equipment, rendering it unusable. Once the equipment is unwrapped, follow the guidelines in the instructional material.

If the equipment must be moved to a final destination after it is placed in storage, it is important to follow all guidelines in the instructional material for moving the equipment.

The switchgear is shipped on skids in protective crates or wrapping. Circuit breakers are shipped in switchgear cells or on separate pallets. 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 it as potential shipping damage to the freight carrier.

Upon receipt, inspect the equipment for damage that may have occurred in transit. Check all items against the packing list provided. Immediately notify the carrier and Schneider Electric of any damages or shortages.

DANGER

HAZARD OF electric shock, explosion, or arc flash Store the equipment in a clean, dry (including no condensation), well ventilated area with an ambient temperature of approximately 70°F (21°C). Place dust covers over circuit breakers. If space heaters are furnished in the assembly, energize them from an external source. When energizing space heaters from an external source, remove the primary current limiting fuses from the control power transformer. If space heaters are not installed in the assembly and the area is cold and damp, use a temporary heating source within the assembly. A minimum of 200 W of heat per cell is recommended. Avoid greasy, smoky heaters that can deposit carbon on insulation that could lead to tracking and insulation breakdown. Failure to follow these instructions will result in death or serious injury.

If the assembly is stored prior to installation, keep it in a clean, dry, well-ventilated area with an ambient temperature of approximately 70°F (21°C). Place dust covers over the circuit breakers. If space heaters are furnished in the assembly, energize them from an external source. 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 assembly control power transformer, open the control power transformer secondary circuit breaker, remove the primary current limiting fuses, and install an out-of-service tag before energizing the space heaters. This action opens the circuit to the control power transformer and does not allow this circuit to backfeed the control power transformer and thus backfeed the main bus.

Claims for shortages or errors must be made in writing to Schneider Electric within 15 days after delivery. Failure to give such notice will constitute unqualified acceptance and a waiver of all such claims by the purchaser. Immediately inspect the switchgear sections 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 points constitute delivery to the purchaser regardless of freight payment and title. All risk of loss or damage passes to the purchaser at that time.

The switchgear is normally shipped in one- or two-section shipping splits. Each section has four lifting eyes bolted on top. If more than two bays are shipped as one section, lifting channels, frames, or spreader bars must be used when lifting. Attach a crane hook in each corner of the shipping split to lift and move the sections. After the shipping split has been placed in position, remove and discard the lifting lugs, if applicable. Screw the bolts back into place to cover the mounting holes.

Factory-built equipment is assembled with fixtures on flat and level floor surfaces to maximize the alignment of the sheet metal components. Door and panel adjustments may be necessary once the equipment is removed from the pallet and placed in position.

If a crane is not available, the sections may be unloaded and moved with a forklift. Rollers under the skids may be used on relatively flat surfaces if other moving equipment is not available or space prohibits the use of other moving methods.

The shipping sections are designed to be lifted by a crane. Attach a sling to the lifting lugs on the roof of each of the shipping sections as shown in Lifting Method. A spreader bar may be necessary to maintain proper lifting angles. If a crane is not available, contact Schneider Electric for special arrangements for unloading the switchgear sections. Conduit should be stubbed a maximum of one inch (25 mm) above the Masterclad floor. Conduit placement must be accurate to assure alignment within the designated conduit area in the floor of the equipment to avoid mechanical interference with the switchgear floor. See following figures.

Floor plates must be installed with cutouts for the conduit to create a barrier to block moisture or pests from entering the switchgear compartment. Employ conduit hubs or a similar system to create a continuous barrier between the area below the switchgear and the switchgear compartment.

CAUTION
DAMAGED LIFTING EYES The interior angle of the lifting sling should not exceed 90°. Angles greater than 90° apply greater inward pressure on the lifting eyes, which can damage and dislodge the lifting eyes from the switchgear. Failure to follow these instructions can result in injury or equipment damage.
