Moisture Contamination Avoidance and Mitigation

If the equipment is stored prior to installation, follow these safety instructions:

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). Storage room ambient temperatures around the equipment should not exceed 104°F (40°C) or fall below 23°F (-5°C). Protect equipment from dust, foreign objects, and rodents. Do not store the equipment in a humid environment. Avoid storing the equipment in a highly gaseous environment. If space heaters are furnished in the equipment, energize them from a remote source. NOTE: When energizing space heaters from a remote source, remove the primary current limiting fuses from the control power transformer (CPT), if equipped. If space heaters are not installed in the equipment and the area is cold and damp, use a temporary heating source within the equipment. A minimum of 200 watts of heat per compartment is recommended. Avoid greasy, smoky heaters that can deposit carbon on insulation that could lead to tracking and insulation breakdown. If moisture, condensation, or chemical ingress is observed, do not energize the equipment. If the equipment is already energized, de-energize it immediately. Failure to follow these instructions will result in death or serious injury.

WARNING
fire hazard Remove all flammable material in the vicinity of the heaters, such as packaging, accessories in boxes, and documentation, before energizing the heaters. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Shipping and Storage Requirements

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 deenergization).
- 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 required.
- 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 to rise to ambient air temperatures before making openings 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 your Schneider Electric representative.
Follow these guidelines every time the equipment is moved to a new storage location or to its final destination.

NOTE: For additional information on moving properly stored equipment, refer to the section Handling.

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.
