Electrical Safety Information

Important Safety Instructions:

• Compliance is required with respect to voltage, frequency, and current requirements indicated on the manufacturer’s label. Connection to a different power source than those specified may result in improper operation, damage to the equipment, or pose a fire hazard if the limitations are not followed.

• There are no operator- serviceable parts inside this equipment. Service should be provided only by a qualified service technician.

• This equipment is provided with a detachable power cord, which has an integral safety ground wire intended for connection to a grounded safety outlet.

• Do not substitute the power cord with one that is not the provided approved type. Never use an adapter plug to connect to a 2-wire outlet, as this will defeat the continuity of the grounding wire.

• The equipment requires the use of the ground wire as a part of the safety certification. Modification or misuse can provide a shock hazard that can result in serious injury or death.

• Contact a qualified electrician or the manufacturer if there are questions about the installation prior to connecting the equipment.

• Protective Earthling is provided by Listed AC adapter. Building installation shall provide appropriate short-circuit backup protection.

• Protective bonding must be installed in accordance with local national wiring rules and regulations.

Operating Frequency Band 5150 – 5850 MHz

To ensure that antenna installations within the 5150-5850 MHz band comply with FCC regulations, specifically the 47 CFR Part 15.407 (a)(1)(i), it is crucial to adhere to guidelines regarding antenna gain, elevation angle, and transmission power control. These measures are pivotal in safeguarding co-channel Non-Geostationary Satellite Orbit (NGSO) and Mobile Satellite Service (MSS) operations against interference.

Key Compliance Requirements:

1. Antenna Gain: When selecting antennas, particularly models 1 and 2, it is essential that gains above 30 degrees from the horizon do not exceed the specified limits. Detailed specifications for each antenna model provide further guidance on their performance and gain profiles.

2. Angle of Elevation: Properly adjusting the angle of elevation for the antenna enhances protection for NGSO/MSS operations, helping to avoid interference.

3. Transmission (Tx) Power Control: The Effective Isotropic Radiated Power (EIRP) should not exceed 21 dBm at any elevation angle above 30 degrees from the horizon. This control is vital in minimizing the risk of interference with other operations.

Installer's Responsibility:

It is the installer's duty to ensure that all radios operating in the 5150-5850 MHz band meet these requirements. Not only does this adherence protect against interference, but it also fulfills the legal obligations as laid out in the FCC regulations.

By carefully selecting the right combination of radio and antenna, adjusting the antenna's angle of elevation, and controlling the transmission power, installers can effectively mitigate interference risks and comply with FCC guidelines.

S.No	Antenna Model	Antenna Gain (dBi)	Antenna Install Degree/Images
1	18 dBi Embedded Panel Antenna	4.67
2	23dBi N-type Panel An-tenna	4.34
3	Omni 10 dBi Antenna	-0.04
4	Sector 18 dBi Antenna	-2.77
5	2 foot 30 dBi Dish Antenna	7.63

The formula used for the calculation of the Transmit Power is given below:

Tx-Power = EIRP – Ga – Gm

EIRP -> Equivalent Isotopically Radiated Power

Ga -> Antenna Gain at 30° in Elevation plane

Gm -> Gain for Multi Input Multi Output

Note : Recommended Spatial Arrangement for EOC655 Devices

To minimize potential interference and ensure the highest performance of EOC655 devices, it is advisable to position them at least 1 meter apart. This spacing helps prevent signal overlap and maximizes device efficiency and reliability by reducing electromagnetic interference. Adhering to this recommended distance is a key practice for maintaining optimal device communication.
