Instructions in Installation, Commissioning and Maintenance must be followed when installing the Nokia InLite and performing any commissioning or maintenance on it. Failure to follow these instructions may be dangerous to the installation, commissioning and maintenance personnel. 1.1 Safety guidelines The safety guidelines are designed as follows: • Warnings alert the reader to dangers which may cause loss of life, physical injury or ill health in any form. The symbol denoting a warning is presented below. WARNING This is a warning! • Cautions are used to denote possible damage to equipment but not dangers to personnel. The symbol denoting a caution is presented below. Caut ion This is a caution!

The Nokia InLite must be installed so that only the authorized personnel have access to its sensitive parts. WARNING Always prevent unauthorized personnel from accessing the Nokia InLite. 2.2 Dangerous voltage Potentially lethal voltage is present within this system. For more information on grounding and on the power supply, refer to System Requirements for Installation and Operation. WARNING Disconnect the Main Unit (MU) from the mains power supply before removing the cable connection cover of the Power Supply Unit (PSU). The warning label shown in Figure 1 is displayed on the power supply cover: D N 00204118 Issue 3-0 en © N okia Corporat ion N okia P ropriet ary and Confident ial 7 (22) W arnings and Caut ions 110/220V A C P A R T IN S ID E R E M O V E T H E CO V E R O N L Y W H E N T H E E Q U IP M E N T IS D ISCO N N E CTE D F R O M M A IN S F igure 1. P ow ersuppl y dangerous vol age w arning l abel WARNING Make sure that applicable high voltage safety precautions are taken before attempting to work on the system with the power connected! WARNING Potentially lethal voltages can be induced if the equipment is not grounded correctly. Ensure that all ground connections are secure and non-removable! WARNING A current plug with ground connection is not sufficient as it can be pulled off. Therefore, the grounding should be fixed. WARNING Connect the MU to the main grounding busbar of the site! Electrical currents from power and communication cables is dangerous. WARNING Ensure that the ground connection is established before an AC power outlet is connected to the MU! Ensure that the ground connection is removed only 8 (22) © N okia Corporat ion N okia P ropriet ary and Confident ial D N 00204118 Issue 3-0 en W arnings after the AC power outlet is disconnected! WARNING Do not rely on the power switch alone to isolate a supply. Unplug the power supply cable from the mains socket if possible. 2.3 Weight WARNING The MU weighs 16.5 kg (33 lb.) without the cover and mounting frame. The three types of Remote Unit (RU) vary in weight between 1.7 kg (3.8 lb) and 11 kg (24.25 lb). The Centralised Power Supply Unit (CPSU) weighs 12.5 kg (27.5 lb). 2.4 Safety and precautions for lasers The optical transmitter used in the laser which is used in the Nokia InLite system contains an optical transmitter which has a power level classification of 3A as defined in EN 60825 (norm). This classification is not considered to be a health hazard. When working with the optical connectors, check that the DL laser on the LU is switched off. WARNING Never look directly at the internal optic connector exit of the transmitter apparatus when it is switched on. The wavelength of the laser is not visible to the human eye, which means that long-term damage will not immediately be known. The symbol shown in Figure 2 denotes an aperture which is the source of invisible radiation.

The RU is classified as a Class 3A laser product. 2.5 Electromagnetic fields and RF power The antenna connected to the RU generates electromagnetic radiation, which can exceed safety levels very close to the antennas. Observe the general guidelines presented in Section 2.5.1, and apply the minimum distance calculation formula presented in Section 2.5.2. 10 (22) © N okia Corporat ion N okia P ropriet ary and Confident ial D N 00204118 Issue 3-0 en W arnings 2.5.1 General guidelines WARNING The antenna generates electromagnetic radiation which can exceed safety levels when a person is working in very close proximity to the antennas. Observe the minimum distance precautions shown in Table 1 when working in close proximity to an antenna operating at full power. WARNING Do not install the MU, RUs or the antennas in areas where there is a potential risk for interference with inadequately shielded medical equipment such as hearing aids, life support devices or other electrically or magnetically sensitive devices. WARNING When installing the MU, RUs or its antennas, the emission of other antennas nearby has to be known beforehand so that ambient emissions can be managed properly. 2.5.2 Formula for minimum safety distances This section presents the formula for calculating the minimum safety distances using the specifications of the particular antenna. m in (G -L ) 10 10 P 4 S F igure 4.

Caut ion Handle the MU, RUs and the CPSU (if used) with care. Do not drop the product or the package containing it. 3.1.2 Weight Caut ion Persons in charge of the transportation and installation of the MU and RUs must note that a fully equipped MU (without the cover and mounting frame) weighs 16.5 kg (33 lb.) and the three types of RUs vary in weight between 1.7 kg (3.8 lb) and 11 kg (24.25 lb). If a CPSU is used, its weight is 12.5 kg (27.5 lb). D N 00204118 Issue 3-0 en © N okia Corporat ion N okia P ropriet ary and Confident ial 17 (22) W arnings and Caut ions 3.1.3 Handling the MU Caut ion Do not lift the MU by the splice cassette box because the cassette or the cassette box may break. Caut ion Take care not to damage the door switch of the MU when lifting the MU. 3.1.4 Installation of the MU, CPSU and the RUs Caut ion Installation of the MU and CPSU above a height of 2 meters is not recommended due to the difficulties of installing and maintaining the units above this height. Personnel who are installing the MU, CPSU and the RUs should be informed about the possible risks and safety measures when elevated. The use of an air platform for installations of RUs at height is recommended. 3.1.5 Grounding The MU may receive damaging overvoltages through the RF jumper cable from the BTS or via power supply lines. Caut ion Sufficient protective grounding is required. A current power plug with ground connection is not sufficient: the grounding of the MU must be based on a fixed grounding cable. 3.1.6 Electrostatic discharge protection Caut ion Always wear a close-fitting antistatic wrist strap around your uncovered wrist when handling the plug-in units of the MU! 18 (22) © N okia Corporat ion N okia P ropriet ary and Confident ial D N 00204118 Issue 3-0 en Caut ions The MU contains Electrostatic Sensitive Devices (ESD) label and stud, which means that they may be permanently damaged by electrostatic discharges encountered in routine handling, testing and transportation. The MU is labelled with an electrostatic sensitive device symbol as shown in Figure 7. F igure 7. El ect rost at ic sensit ive device l abel Electrostatic discharges are caused by direct contact or by an electrostatic field. If a charged body approaches an electrically conducting surface, the acquired potential is discharged. An equalizing current can then flow in the associated circuitry and generate permanently damaging voltages by induction. The human body should be grounded at the same potential as the component or equipment being handled. A wrist strap creates an equipotential electrical connection between the object and the human. The MU has a grounding point (ESD stud) to which a wrist strap must be connected, as seen in Figure 8.

Incorrect polarity causes damage to the equipment. Caut ion The MU power switch does not disconnect the equipment from the power network. The separate main switch on the site is considered a disconnect device for safety and service purposes. Alternatively, the power supply cable can be unplugged from the mains socket. Caut ion Do not connect AC power until you have verified that the line voltage is correct! The correct power supply is 110 VAC or 220 VAC. 3.2.1.2 Grounding of MU AC power supply Caut ion Ensure that the MU is connected to a grounded power outlet! 3.2.1.3 PSU Caut ion Double pole/neutral fusing.

Caut ion RUs can be used with 110 VAC or 220 VAC or -48 VDC. However the 110/220 VAC and -48 VDC supplies are connected via different connectors. The required type of RU (110/220 VAC or -48 VDC) must be specified at the time of ordering. 22 (22) © N okia Corporat ion N okia P ropriet ary and Confident ial D N 00204118 Issue 3-0 en
