Installation procedure

Electric wiring

Wiring connection method : (the wiring diagram is attached inside the machine)

1) Ring terminal connection method

If there is a ring at the end of the connection wire, the wire connection method is as shown in the right figure. Remove the terminal screw and insert it through the ring at the connection wire end, then connect to the terminal board and fasten the screw.

2) Straight terminal connection method

If there isnt a ring at the end of the connection wire, the connection method shall be: loosen the terminal screw, insert the connection wire end completely into the terminal board and fasten the screw. Pull the connection wire outwards slightly to confirm it is clamped tightly.

Connection method f or ring terminal

3) Clamping method of the connection wire

After wire connection is finished, the connection wire must be pressed tightly with wire clips, which shall apply to the outer sheath of the connection wire.

Wire connection for built-in indoor unit

Insert from outside the connection wire and signal transmission wire through the wall hole with pipeline already arranged.

Pull out the front ends of connection wire and signal wire and make a circle on the signal wire.

Connect the connection wire according to the connection method and indoor and outdoor wiring diagram.

Pull the connecting conductor outwards slightly to confirm it is clamped tightly.

Connect the plug for connecting the signal wire with the plug of the signal wire connected from the indoor unit.

After wire connection is finished, install wire clips using the same method for connection wire clamping.

Note: When connecting the indoor unit and the outdoor unit, please do connect the wires with the same color terminals.

Notes:

Before connecting the conductors between indoor unit and outdoor unit, check for the nu- mber on the indoor and outdoor units connecting terminals. Connect the terminals with the same color and number with a wire.

Wrong connection would damage the controller of the air conditioner or the machine cou- ldnt operate.

Do not connect the connection wire and signal wire with the same cable. They shall be co- nnected respectively to ensure system normal operation.

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.
