2. INTRODUCTION 2.1. PURPOSE Cellular telephone systems transmit signals in two directions between a 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. Such a system contains an optical Master Unit and several Remote Units.
The ION-M7P/7P/19P/19HP is available in single (SISO) or multi-channel (MIMO) configuration supporting 700 MHz, LTE, and two1900 MHz bands in parallel. It has been specifically tested and optimized for LTE, OFDM, CDMA, WCDMA, and GSM signals. The ION is easily set-up and supervised via a graphical user interface (GUI). Remote units can be commissioned through the use of built-in test equipment. An autoleveling function compensates for the optical link loss making installation easy and quick.
3. COMMISSIONING 3.1. MECHANICAL INSTALLATION 3.1.1. General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 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.
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.
3.1.2. Wall-Mounting Procedure Check the suitability of the wall-mounting kit and the wall. Remove the protective cover from the top of the Remote Unit by pulling it strongly to the front. Protective cover Mark the position of the drilling holes (for exact measurements refer to the wall mounting plan that is part of the delivery). Drill three holes at the marked positions and insert dowels*.
3.2. ELECTRICAL INSTALLATION 3.2.1. General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 1. This unit contains dangerous voltages. Loss of life, severe personal injury or property damage can be the result if the instructions contained in this manual are not followed. 2. It is compulsory to ground the unit before connecting power supply. A grounding bolt is provided on the cabinet to connect the ground-bonding cable. 3.
13. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 14. 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. 15.
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 3-4 Grounding bolt with loosened hex nut, exemplary figure 3-5 Grounding bolt, schematic view After loosening the hex nut, connect the earth-bonding cable between the two washers as illustrated in the figures above.
Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of 7-16 DIN connectors with 1-1/4 in opening to tighten the 7/16-type antenna connectors. For example, use torque wrench of item no. 244377 available from the Andrew e-catalog. Do NOT use your hands or any other tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit.

PIN 4 = PE (green/ yellow cable) For the AC power supply connection, a minimum cross section of 1.5 mm2 is required. Each wire must observe the applicable national regulations regarding loop impedance, voltage drop, and methods of installation. Make sure to connect the correct voltage to the unit.
3.2.6. Connection of Optical-Fibre-Cable - Rules Optical signals are transmitted by use of optical fibres. When connecting these fibres observe the following instructions. Note: Care should be taken when connecting and disconnecting fibreoptic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fibre-optic connectors not in use. In general, optical fibres do not need special protective measures.
Remove fibre-optic protective caps. Do not bend the fibre-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission. Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibre-optic cable that will be inserted in the optical connectors on the donor interface box. Blow out the laser receptacle with clean and dry compressed air to remove any particulate matter.
For plug assembly, observe the following instruction: 1. Pass one or two contacts through the backshell and the clamp ring. 2. Place the contact(s) on the lower insulation body by pushing the groove of the contact into the cavity. If there is only one contact, cavity A must be used. * 3. Then, mount the upper insulation body on the lower insulation body. ** Upper insulation body Cavity B Cavity A 4. Bring the insulator into the plug.
7. Bring the plastic ring over the cable(s), push it into the backshell and compress the seals and plastic ring by screwing the clamp ring tight (no gap) using a spanner with opening 20. *** Screw tight until gap is closed 8. Connect the plug to the optical-fibre 9.
