WARNING
POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY Change default passwords to minimize instances of unauthorized access to device settings and information. Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks. Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection). Use cybersecurity best practices (for example: least privilege, separation of duties) to minimize chances of unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Moisture Contamination Avoidance and Mitigation

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). If heaters are furnished in the assembly, energize them from an external source. When energizing heaters from an external source, remove the primary and secondary overcurrent protective devices from the control power transformer. If 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 section is recommended. Avoid greasy, smoky heaters that can deposit carbon on insulation, which 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, Receiving, and Storage Requirements

This equipment does not achieve its ratings until it is installed per record/as-built drawings, 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.

Treat the equipment as if it is in storage until it is installed and operational. The storage area must be clean, dry (75% or less relative humidity), and climate-controlled with proper ventilation.
To keep the equipment dry, use of heaters is required in some cases (for example, during seasonal or low periods of electrical 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, set the thermostats and/or humidistats to mitigate condensation. A minimum of 200 W of heat per section is recommended.
- If heaters are 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 the ambient air temperature before making openings in or otherwise 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 (no tarp) over-the-road transportation that risks exposing the equipment to the elements. Leave the factory shipping wrap around the equipment on the equipment until the equipment is ready for inspection 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.

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 help prevent condensation and alternate heat sources are required. If environmental controls such as a thermostat or humidistat are used, their settings must be sufficient to mitigate condensation and always remain operational. Consult the engineer of record for the appropriate environmental control settings.

Exposure to Moisture, Chemicals, and Condensation

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.
