Installation procedure

Electrical requirements

The power supply shall be connected from the outdoor side. (For models with electric-aided heating function, the power supply to the indoor unit shall be connected at the indoor side The power cord size is 3 x (1.25-1.5)mm2, type of YZW).

A separate power circuit shall be supplied and connected by a qualified electrician according to the wiring rules specified in the corresponding national standard.

A current leakage breaker must be installed.

The connection method of power cord is " Y " type. If the power flexible cord is damaged, it shall be replaced by the manufacturer or its service department or similar qualified technician so as to avoid risks.

Power cord plug: L should be connected to the live wire, N should be connected to the neutral wire and to the ground wire.

Connection wire size: 3 x (1.25-1.5) mm2, type of YZW.

Signal transmission wire size: 2 x (0.75-1.25) mm2 (shielded wire).

Power cord, connection wire and signal wire shall be provided by the user.

AE092FCAHA, AE182FCAHA specifications

MRV Communications has established itself as a leader in the field of networking solutions, and among its impressive product lineup, the AE182FCAHA and AE092FCAHA stand out as robust fiber optic devices designed to meet the demands of modern network architectures. These devices are particularly tailored for enterprise and service provider environments where high-speed data transmission and reliability are paramount.

The AE182FCAHA is engineered to handle complex networking needs with a combination of high throughput and advanced routing capabilities. It supports multiple protocols, which enables seamless integration into existing infrastructures. This device is capable of delivering up to 10 Gbps of throughput, ensuring that even the most data-intensive applications run smoothly. With its built-in redundancy features, the AE182FCAHA also assures minimal downtime, a critical aspect for mission-critical operations.

Similarly, the AE092FCAHA offers a compelling solution for medium to large-scale networks, focusing on simplified management and high-performance. This device is designed to facilitate bandwidth-intensive applications such as video streaming and large database transactions, with a capacity that supports up to 1 Gbps. It employs sophisticated Quality of Service (QoS) features that prioritize latency-sensitive traffic, making it ideal for real-time communication platforms.

A standout characteristic of both devices is their use of advanced optical technologies. Equipped with DWDM (Dense Wavelength Division Multiplexing), they can transmit multiple signals over a single fiber strand, vastly improving bandwidth efficiency and reducing operational costs. The use of fiber optics also enhances signal integrity over long distances, making these devices suitable for enterprises with expansive geographic footprints.

In terms of management and usability, both the AE182FCAHA and AE092FCAHA come with user-friendly interfaces that streamline configuration and monitoring tasks. Their compatibility with SNMP (Simple Network Management Protocol) allows network administrators to easily integrate them into larger management systems, ensuring proactive monitoring and quick troubleshooting.

Overall, MRV Communications' AE182FCAHA and AE092FCAHA are innovative solutions designed to meet the rigorous demands of today's networking environments, combining high performance, advanced features, and ease of management. Organizations looking to enhance their network infrastructure will find these devices to be dependable assets that support both current requirements and future expansion.
