Safety Guidelines Hardware Installation Guide 2.1. General Safety Guidelines The following lists general safety guidelines when working with the WipLL equipment: ! The user and the installer should be aware that changes and modifications not expressly approved by Airspan Networks could void the user’s authority to operate the equipment. ! Never install equipment that is damaged. ! Only qualified personnel should be allowed to install, replace, and service the WipLL equipment. 2.2.
Hardw are Installation Guide Safety Guidelines 2.2.1. Handling Electrostatic Devices Electrostatic devices are those devices that may be damaged by the inadvertent discharge of static electricity from a charged body. The risk of damage, due to electrostatic discharge (ESD) to a device, may cause the device to fail suddenly, or it may induce a partial defect within the device, which will cause subsequent premature failure.
Safety Guidelines Hardware Installation Guide 2.2.2. Grounding Only certain WipLL devices require additional grounding. WipLL devices that do not require additional grounding have grounding at the main supply outlet. The following table lists the WipLL devices’ grounding requirements.
Hardw are Installation Guide Safety Guidelines 2.4. Installing Outdoor & Indoor Units and Third-Party External Antennas Warning: It is the responsibility of the person installing the WipLL system to ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), that only those antennas certified with the product are used. The use of any antenna other than those certified with the product is expressly forbidden in accordance with FCC rules CFR47 part 15.204.
Safety Guidelines Hardware Installation Guide 2.6. Radio Interference Prevention The digital portion of the transceiver has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
Hardw are Installation Guide Safety Guidelines ! Cable routes are to be defined in the site-specific documentation. ! Data and DC power cables running parallel to AC power cables shall be separated by a minimum distance of 200 mm. However, it is permissible to allow these cables to cross each other at right angles. ! Observe recommended minimum bend radii when installing copper cables.
Safety Guidelines Hardware Installation Guide 2.7.2. Labeling The following labels are required to be fitted to WipLL equipment: ! Voltage Warning ! High Earth Leakage Current ! Signal Cable Designation 2.7.2.1. Voltage Warning ! Where mains power is fed from separate phases, then appropriate warning labels must be fitted to warn of the increased danger. ! The AC equipment used in the BSPS cabinet must carry a relevant voltage warning label specific to the country in which it is being installed.
Hardw are Installation Guide Safety Guidelines 2.7.2.2. High Earth Leakage Current If equipment earth leakage current exceeds 3.5 mA, a warning label as shown in Figure 2-1 will be fitted to the rear of the main power rack alongside the AC inlet terminal block. WARNING HIGH LEAKAGE CURRENT Earth connection essential Before connecting supply Figure 2-1: Warning label if earth leakage current exceeds 3.5 mA 02030311-06 Airspan Networks Ltd.
Safety Guidelines Hardware Installation Guide 2.7.2.3. Signal Cable Designation A wrap around identification label, similar to that shown in Figure 2-2, is to be fitted to both ends of WipLL data cables. Care should be taken to ensure that the cable identification information is clearly visible. The labels are to be supplied with the installer’s folder. Identify the cable as detailed in the CROL supplied by Contract Engineering. Fit the label 100 mm from the cable end.
