All Safety Precautions

To ensure human safety and equipment safety, comply with all the safety precautions marked on the equipment and instructed in this document.

WARNING, CAUTION, and DANGER items in this document do not cover all the safety cautions and are only supplementary to the safety cautions.

Local Laws and Regulations

When operating a device, abide by local laws and regulations. The safety precautions instructed in the document are supplementary to the local laws and regulations.

Basic Installation Requirements

Only trained and qualified personnel are allowed to install or maintain Huawei equipment. Familiarize yourself with all safety precautions before performing any operation on the equipment.

• Only the trained and qualified personnel are permitted to install, operate, and maintain Huawei equipment.

• Only the qualified personnel are permitted to dismantle safety appliances and repair Huawei equipment.

• Only the personnel certified or authorized by Huawei are permitted to replace or change Huawei equipment or parts of Huawei equipment (including software).

• The operating personnel must immediately report the faults or errors that may cause safety problems to the person in charge.

Grounding Requirements

Equipment that needs to be grounded must meet the following requirements:

• When installing the equipment, ground the equipment before any operations and remove the ground cable only after you remove all the other components and cables from the equipment.

• Ensure that the ground conductor is intact.

• Do not operate the equipment in the absence of a suitably installed ground conductor.

• The equipment must be connected to the PGND permanently. Before operating the equipment, check the electrical connections of the equipment and ensure that the equipment is properly grounded.

Personal Safety

• Do not operate the equipment and cables in a thunderstorm.

• To avoid electric shocks, do not connect safety extra-low voltage (SELV) circuits to telecommunication network voltage (TNV) circuits.

• Invisible laser beams will cause eye damage. Do not look into bores of optical modules or connectors of optical fibers without eye protection.

• Before performing any operation on the equipment, wear ESD clothing and ESD gloves or an ESD wrist strap. Remove conductive objects like jewelry and watches to avoid electric shock or burn.

• In case of fire, immediately leave the building or equipment deployment site and press the fire alarm button or call the fire department. Never enter the building on fire again in any situation.

Equipment Safety

• Before any operation, install the equipment firmly on the ground or other rigid objects, such as on a wall or in a rack.

• When the system is working, ensure that the ventilation hole is not blocked.

• When installing panels, use necessary tools to fasten the screws.

• After equipment installation is complete, clean up the packing materials.

High Voltage

DANGER:

• Direct contact with a high-voltage power source or indirect contact through damp objects can be fatal.

• Misoperations on high-voltage facilities may result in fire, electric shock, or other accidents.

High Leakage Current

CAUTION:

To protect personal and equipment safety, ground the equipment before powering it on.

If a high leakage current mark is labeled near the power connector of the equipment, you must connect the PGND terminal on the shell to the ground before connecting the equipment to an AC input power supply. This is to prevent the electric shock caused by leakage current of the equipment.

Power Cable

DANGER:

Never install or remove the equipment or power cables while the power is on. The electric arc or spark generated between a power cable and conductor may cause fire or eye damage.

• Before installing or removing power cables, you must power off the equipment.

• Before connecting a power cable, verify that the label on the power cable is correct.

Fuses

CAUTION:

If the fuse on the equipment is blown, replace the fuse with a fuse of the same type and specifications to ensure safe operation of the equipment.

Precautions

Pay attention to the following points when installing this antenna:

• The distance between the installation height and the height of antennas of vehicle-mounted APs is less than 30 cm. It is recommended that it be installed at a position 20 cm higher than the antennas of vehicle-mounted APs.

• The tubular central axis of the antenna is horizontally paralleled with the rails and the angle between the antenna and wall is less than 1°. Do not incline the antenna towards the wall.

• If you customize mounting brackets, ensure that the distance between the central axis of the antenna and the installation wall is no less than 15 cm.Wall Mounting

1. Fix the mounting bracket to the wall, adjust the installation position using a level, and mark positions of four mounting holes.

   

2. Use a hammer drill to drill holes at the four marked positions. Screw the nut into the expansion bolt, hammer the expansion bolt into a hole until the flat washer is closely attached to the wall. Remove the nut, spring washer, and flat washer in order.
   
   

3. Fix the antenna onto the mounting bracket, fit flat washers, spring washers, and nuts in order, and tighten the nuts (the tightening torque is 5 N•m). Stretch the feeder port out of the hole of the mounting bracket.

4. Pinch the mounting bracket on the expansion bolts, fit flat washers, spring washers, and nuts in order, and tighten the nuts (the tightening torque is 5 N•m).

   

RF Cable Connection

Connect the feeder connector to the radio interface of an AP using an RF transit cable (sold separately) and tighten the connector to the interface. A 1 N•m tightening torque is recommended for the type-N connector.

The following table lists the RF transit cables and connectors used.

The requirements on connections between the antenna and the AP's radio interfaces are as follows:

• Feeders of the same antenna must be connected to radio interfaces of the corresponding frequency bands on the same AP.

• Feeder ports whose polarization directions are +45° and -45° on an antenna are connected to radio interfaces A and B of an AP respectively, and the feeder port whose polarization direction is 90°is connected to radio interface C of the AP.

Take the AP9132DN as an example. The following figure shows the RF cable connection on the AP9132DN.

RF Cable Deployment Requirements

• Use a short feeder cable to connect the antenna to an AP.

• It is recommended that you connect a 50 ohm RF load to an idle antenna interface and wrap the RF load with both the insulation and waterproof tape.

• Wrap the RF cable in single-layer PVC insulation tape, triple-layer waterproof tape, and then triple-layer PVC insulation tape.

• Before wrapping the waterproof tape, stretch the tape evenly until it is 1/2 the width as before. With each layer of tape wrap the cable tightly and ensure that each layer covers more than 50% of the layer beneath it.

• Wrap the triple-layer tape from bottom to top, from top to bottom, and then from bottom to top again.

• Bend radius requirements: RG-8U RF cable: > 150 mm; 1/2" RF cable:> 50 mm; 7/8" RF cable: > 250 mm. One inch (1") equals 25.4 mm.

RF Cable Connections

1. Antenna interfaces of Huawei outdoor APs provide a 5 kA surge protection capability. In general, no additional surge protective device needs to be installed, and the RF cables are directly connected to the antenna interfaces.

   

   NOTE:

   Outdoor APs support built-in surge protection on all interfaces, but the surge protection works only when the outdoor APs are grounded.

2. If a higher surge protection capability is required, you need to purchase a surge protective device separately. When installing the surge protective device, ensure that it is connected to a ground cable.
