1 Scope

This document specifies the additional input sockets for information and communication technology (ICT) equipment installed in data centers and telecommunications center rooms.

The requirements are that these appliance input sockets are compatible with both AC and DC power.

According to this document, electrical accessories may be used by general personnel in the data center only if the voltage distribution system meets the following requirements.

---For DC voltage distribution systems, the values defined in Chapter 1 of GB/T 47637.1-2026 apply;

---For AC voltage distribution systems, the voltage shall not exceed 250VAC, and the rated current shall meet the requirements of the standard valve.

The appliance couplers conforming to this document are suitable for use in ambient temperatures generally not exceeding 60°C, with a minimum ambient temperature of -5°C.

Appliance couplers are not suitable for the following situations.

---Used to replace plug and socket systems conforming to IEC TS62735 series standards;

---Used to replace plug and socket systems conforming to IEC 60884 series standards;

---Used to replace luminaire connection devices (DCLs) or luminaire matching couplers (LSCs) conforming to IEC 61995 (all parts).
