Preparing for Installation

2.1 Safety Precautions
Note

• To avoid personal injury and device damage, carefully read the safety precautions before you install the device.
• The following safety precautions may not cover all possible dangers.

2.1.1 General Safety Precautions

• Do not expose the AP to high temperature, dusts, or harmful gases. Do not install the AP in an inflammable or explosive environment. Keep the AP away from EMI sources such as large radar stations, radio stations, and substations. Do not subject the AP to unstable voltage, vibration, and noises.
• The installation site should be free from water flooding, seepage, dripping, or condensation. The installation site should be selected according to network planning, communications equipment features, and considerations such as climate, hydrology, geology, earthquake, electrical power, and transportation.
• The installation site should be dry. It is not recommended that the AP be installed in a place near the sea.
  Keep the device at least 500 meters away from the ocean and do not face it towards the sea breeze.
• Do not place the device in walking areas.
• During the installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be hooked by the chassis.
• Keep tools and components away from walking areas.

2.1.2 Handling Safety

• Prevent the AP from being frequently handled.
• Cut off all the power supplies and unplug all power cords before moving or handling the device.

2.1.3 Electric Safety
Warning

• Improper or incorrect electric operations may cause a fire, electric shock, and other accidents, and lead to severe and fatal personal injury and device damage.
• Direct or indirect contact with high voltage or mains power supply via wet objects may cause fatal dangers.
• Observe local regulations and specifications during electric operations. Only personnel with relevant qualifications can perform such operations.
• Check whether there are potential risks in the work area. For example, check whether the ground is wet.
• Find the position of the indoor emergency power switch before installation. Cut off the power switch in case of accidents.
• Check the AP carefully for confirmation before shutting down the power supply.
• Do not place the device in a damp/wet location. Do not let any liquid enter the chassis.
• Keep the AP far away from grounding or lightning protection devices for power equipment.
• Keep the AP away from radio stations, radar stations, high-frequency high-current devices, and microwave ovens.

2.1.4 Storage Security
For proper working of the AP, the AP must be stored in an environment based on the storage temperature/humidity requirements in Specifications.
Caution
If the AP is stored for more than 18 months, power on the AP and run it for consecutive 24 hours to activate the AP.
2.2 Installation Environment Requirements
The installation site must meet the following requirements.
2.2.1 Bearing Requirements
Evaluate the weight of the device and its accessories (such as the bracket and power supply module), and ensure that the ground of the installation site meets the requirements.
2.2.2 Ventilation Requirements
Reserve sufficient space in front of the air vents to ensure normal heat dissipation. After various cables are connected, bundle the cables or place them in the cable management bracket to avoid blocking air inlets.
2.2.3 Space Requirements
Maintain a minimum clearance of 0.4 m around the device to ensure proper cooling and ventilation.
2.2.4 Temperature/Humidity Requirements
To ensure the normal operation and a prolonged service life of the AP, maintain an appropriate temperature and humidity in the installation environment.
The installation environment with too high or too low temperature and humidity for a long period of time may damage the AP.

• In an environment with high relative humidity, the insulating material may have bad insulation or even leak electricity.
• In an environment with low relative humidity, the insulating strip may dry and shrink, loosening screws.
• In a dry environment, static electricity is prone to occur and damage the internal circuits of the AP.
• Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the AP and severely affecting its service life.

Note
The ambient temperature and humidity of the device are measured at the point that is 1.5 m (59.06 in.) above the floor and 0.4 m (15.75 in.) before the device when there is no protective plate in front or at the back of the device.
2.2.5 Grounding Requirements
A good grounding system is the basis for stable and reliable operation of the device, preventing lightning strokes and resisting interference. Carefully check the grounding conditions at the installation site according to the grounding requirements, and perform grounding operations properly as required.

• Safety Grounding
• The device using AC power supply must be grounded by using the yellow/green safety grounding cable.
  Otherwise, an electric shock may occur when the insulation resistance between the power supply and the device enclosure decreases.

Caution
The building must provide the protective grounding connection to ensure that the device is connected to the protection location.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, down conductor, and connector to the grounding system, which usually shares the power reference ground and ground cable. The lightning discharge ground is targeted for the facility.
EMC Grounding
The grounding required for EMC design includes the shielding ground, filter ground, noise and interference suppression, and level reference. All the above constitute the comprehensive grounding requirements. The resistance of earth wires should be less than 1 Ω. The cabinet should be grounded according to the requirements before the device works.
2.2.6 Anti-interference Requirements

• Take interference prevention measures for the power supply system.
• Keep the AP away from the grounding equipment or lightning and grounding equipment of the power device as much as possible.
• Keep the AP far away from high-frequency current devices such as the high-power radio transmitting station and radar launcher.
• Take electromagnetic shielding measures when necessary.

2.2.7 Lightning Protection Requirements
The RG-AP680P-L can guard against lightning strikes. As an electric device, too strong lightning strikes may still damage the device. Take the following lightning protection measures:

• Ensure that the neutral point of the AC power socket is in good contact with the ground.
• It is recommended that you install a power lightning arrester in front of the power input end to enhance the lightning prevention for the power supply.
• Keep the grounding connection within 30 m, and use a 40 mm x 4 mm or 50 mm x 5 mm ground bar of hot- dip zinc-coated flat steel sheet.
• When the connection cable between the main grounding conductor and local equipotential earthing terminal board (LEB) on each floor is short, use a stranded copper wire with a sectional area not less than 1.318 mm 2 (16 AWG) for the connection cable.
• Use a shielded network cable if possible, ensure that devices connected to both ends of the shielded network cable are reliably grounded, and make sure that the sheath of the shielded network cable is also grounded if possible. If no shielded network cable is available, wire the network cable through a steel pipe and bury the steel pipe for lead-in, and properly ground both ends of the steel pipe.
• Use a power cable with the PE end to ground the power supply (AC). Ensure that the PE end is properly grounded, with a ground resistance less than 5 ohms. Do not use a two-wire power cable with only the live (L) wire and neutral (N) wire. Do not connect the N wire to the protection ground cable of other communication devices, and ensure that the L wire and N wire are properly connected.
• Ensure that the ground resistance is less than 5 ohms. In areas with high soil resistivity, reduce the soil resistivity via measures such as spreading resistivity reduction mixture around the grounding conductor.

2.2.8 Waterproof Requirements
Cap unused ports to ensure waterproof. Connect the network cable, fiber-optic jumper, and AC power cable to the AP after they pass through the corresponding waterproof plugs to ensure waterproof.
2.2.9 Other Requirements

Table 7-4 Fiber-Optic Cable Connections

7.2 Cabling Recommendations
During installation, route cable bundles upward or downward along the sides of the rack depending on the actual situation in the equipment room. All cable connectors should be placed at the bottom of the cabinet rather than be exposed outside of the cabinet. Power cords are routed beside the cabinet, and top cabling or bottom cabling is adopted according to the actual situation in the equipment room, such as the positions of the DC power distribution box, AC socket, or lightning protection box.

• Requirement for the Minimum Cable Bend Radius
  ○ The bend radius of a power cable, communication cable, or flat cable should be over five times greater than their respective diameters. The bend radius of these cables that is often bent or plugged or unplugged should be over seven times greater than their respective diameters.
  ○ The bend radius of a fixed common coaxial cable should be over seven times greater than its diameter.
  The bend radius of the common coaxial cable that is often bent or plugged should be over 10 times greater than its diameter.
  ○ The minimum bend radius of a high-speed cable, such as an SFP+ cable should be over five times the overall diameter of the cable. If the cable is frequently bent, plugged or unplugged, the bend radius should be over 10 times the overall diameter.
• Precautions for Cable Bundling
  ○ Before cables are bundled, mark labels and stick the labels to cables wherever appropriate.
  ○ Cables should be neatly and properly bundled in the cabinet without twisting or bending, as shown in Figure 7-1.○ Cables of different types (such as power cables, signal cables, and ground cables) should be separated in cabling and bundling. Mixed bundling is not allowed. When they are close to each other, it is recommended that crossover cabling be adopted. In the case of parallel cabling, maintain a minimum distance of 30 mm between power cords and signal cables.
  ○ The cable management brackets and cabling troughs inside and outside the cabinet should be smooth without sharp corners.
  ○ The metal hole traversed by cables should have a smooth and fully rounding surface or an insulated lining.
  ○ Proper cable ties should be selected to bundle up cables. It is forbidden to connect two or more cable ties to bundle up cables.
  ○ After bundling up cables with cable ties, cut off the remaining part. The cut should be smooth and trim,○ When cables need to be bent, bind them first but do not tie cable ties within the bend. Otherwise, considerable stress may be generated in cables, breaking cable cores, as shown in Figure 7-3.○ Cables not to be assembled or remaining parts of cables should be folded and placed in a proper position of the cabinet or cable trough. The proper position indicates a position that will not affect device running or cause device damage or cable damage during debugging.
  ○ 220 V and –48 V power cables must not be bundled on the guide rails of moving parts.
  ○ The power cables connecting moving parts such as door grounding wires should be reserved with some access after being assembled to avoid suffering tension or stress. When a moving part reaches the installation position, the remaining cable part should not touch heat sources, sharp corners, or sharp edges. If heat sources cannot be avoided, high-temperature cables should be used.
  ○ When screw threads are used to fasten cable terminals, the bolt or screw must be tightly fastened, and anti-loosening measures should be taken, as shown in Figure 7-4.

① Flat washer
② Nut
③ Spring washer
④ Flat washer

• Hard power cords should be fastened in the terminal connection area to prevent stress on terminal connection and cable.
• Do not use self-tapping screws to fasten terminals.
• Power cables of the same type and in the same cabling direction should be bundled up into cable bunches, with cables in cable bunches clean and straight.
• Bundle up cables using cable ties based on the following table.

Cable Bunch Diameter (mm)	Distance Between Every Binding Point (mm)
10	80–150
10–30	150–200
30	200–300

• No knot is allowed in cabling or bundling.
• For wiring terminal blocks (such as circuit breakers) with cord end terminals, the metal part of the cord end terminal should not be exposed outside the terminal block when assembled.
