2 Functional Description 2. FUNCTIONAL DESCRIPTION 2.1. PURPOSE Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system.

Fan-Protection Kit In order to protect the fan unit (e.g. against rain), a protective cover to be mounted over the air inlet is delivered with the unit. For more details see chapter 3.1.4 Mounting of Fan Protection. Mounting of the fan-protection kit is only mandatory for outdoor applications, however, not mandatory for indoor applications. 2.3.2.
3 Commissioning 3. COMMISSIONING 3.1. MECHANICAL INSTALLATION 3.1.1. General Read the health and safety warnings in chapter 1.2. 1. Do not install the unit in a way or at a place where the specifications outlined in the Environmental and Safety Specifications leaflet of the supplier are not met. 2. It is recommended only to use the mounting hardware delivered by the supplier. If different mounting hardware is used, the specifications for stationary use of the Remote Unit must not be exceeded.
User’s Manual for Remote Unit ION™-M80/90/19P 7. A spacing of 40 mm (1.58 inch) around the unit is required. 8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two lid openings (one for the air inlet and the other for the air outlet) have to be provided. Do not block these air inlets and outlets when mounting the Remote Unit. The size of each opening must equal at least 17 x 17 cm (290 cm2). Make sure, too, there is no thermal short circuit between the air inlet and air outlet.
3 Commissioning 3.1.2. Wall-Mounting Procedure Check the suitability of the wall-mounting kit and the wall. Mark the position of the drilling holes (for measurements refer to figure 3-1 Wall mounting). Drill four holes at the marked positions and insert dowels *. Use a cap nut or lock nut to screw the four dowel screws into the dowels and put the distance tubes over the screws. Hang the mounting brackets of the Remote Unit into the screws, and fasten them immediately using the washers and nuts.
User’s Manual for Remote Unit ION™-M80/90/19P 3.1.3. Pole-Mounting Procedure Standard mounting hardware cannot be used to mount the Remote Unit to a pole, a column or other similar structures. Additional hardware must be used for this type of installation. Such a pole-mounting kit could include two threaded rods M8, two U-beams and mounting material like bolts and nuts.

Loss of life, severe personal injury or property damage can be the result if the instructions contained in this manual are not followed. 2. Ground the unit before connecting power supply. A grounding bolt is provided on the cabinet to connect the ground-bonding cable. 3.
User’s Manual for Remote Unit ION™-M80/90/19P 12. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection), depending on the individual application, in order to avoid damage caused by overcurrent. 13. Observe the labels on the front panels before connecting or disconnecting any cables. 3.2.2.
3 Commissioning 3.2.3. Grounding Grounding must be carried out. Connect an earth-bonding cable to the grounding connection provided at the outside of the Remote Unit (see chapter 3.2.2 Connections). Do not use the grounding connection to connect external devices. figure 3-6 Grounding bolt with loosened hex nut figure 3-7 Grounding bolt, schematic view After loosening the hex nut, connect the earth-bonding cable between the two washers as illustrated in the figures above.
User’s Manual for Remote Unit ION™-M80/90/19P 3.2.4. Power Connection Before connecting electrical power to the units, the system must be grounded as described in the previous chapter. Mains power must be connected at the mains connector of the unit (see chapter 3.2.2 Connections). The power supply plug is part of the delivery. The correct wiring of the power supply plug is as follows: figure 3-8 AC mains plug figure 3-9 DC mains plug For the AC power supply connection, a minimum cross section of 1.
3 Commissioning 3.3. CONNECTION OF THE ANTENNA CABLES The Remote Unit has N-type antenna connectors. For its location please refer to chapter 3.2.2 Connections. For mounting the cable connectors, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications.
User’s Manual for Remote Unit ION™-M80/90/19P System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fiber, at the input and output of the device which has to be measured.
3 Commissioning Cleaning Procedure for Fiber-Optical Components: Any contamination in the fiber connection results in additional optical transmission loss which could cause whole system failure. It is thus recommended that every fiber connector be inspected and cleaned prior to mating. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber-optic connection. When you clean fiber components, always complete the following steps carefully: 1.
