1.4Safety 1.4.1 General

This manual uses NOTES along with CAUTION and WARNING symbols to draw your attention to important operational and safety information.

A NOTE marks a short message in the information to alert you to an important detail.

A CAUTION safety alert appears with information that is important for protecting your equipment and performance. Be especially careful to read and follow all cautions that apply to your application.

A bold text WARNING safety alert appears with information that is important for protecting you from harm and the equipment from damage. Pay very close attention to all warnings that apply to your application.

A safety alert symbol

precedes a general WARNING or CAUTION safety statement.

A safety alert symbol precedes an electrical shock hazard WARNING or CAUTION safety statement.

1.4.2 Safety Summary

The following statements are general guidelines followed by warnings and cautions applicable throughout the manual. Before performing any installation, operation, maintenance, or troubleshooting procedure, read and understand all instructions, recommendations, and guidelines contained within this manual.

CAUTION

All maintenance and/or repairs must be performed by a journeyman refrigeration mechanic or air-conditioning technician.

CAUTION

When moving the unit, it should be kept in its normal installed position. If the unit is not kept level and vertical, damage to the compressors will result.

WARNING

Never operate the unit with any cover, guard, screen panel, etc. removed unless the instructions specifically state otherwise; then do so with extreme caution to avoid personal injury.

CAUTION

Never lift any component in excess of 35 pounds without help. If a lifting device is used to move a unit, make sure it is capable of supporting the unit.

CAUTION

When working on electrical equipment, remove all jewelry, watches, rings, etc. Keep one hand away from the equipment to reduce the hazard of current flowing through vital organs of the body.

CAUTION

Always turn off the service disconnect switch and disconnect the main power supply to the equipment. Follow a lock-out tag-out procedure to ensure that power is not inadvertently reconnected.

WARNING

This unit is fed by incoming power wires. Even with the service disconnect switch in the “Off” position, power may still be “live” between the switch and the main power source. When performing service, always ensure that main power is disconnected from the unit.

CAUTION

Equipment may contain components subject to electrostatic discharge (ESD). Before attempting to mount or service these electronic devices, make sure you have no charge built up by touching a ground source. When possible, use a wrist-grounding strap when working on or near electronic devices.

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
