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 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).
Warnings and Cautions18 (22)© Nokia Corporation DN00204118Nokia Proprietary and ConfidentialIssue 3- 0 enCautionCautionCautionCautionCaution3.1.3 Handling the MU Do not lift the MU by the splice cassette box because the cassette or the cassette box may break. 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 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 GroundingThe MU may receive damaging overvoltages through the RF jumper cable from the BTS or via power supply lines. 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 Always wear a close-fitting antistatic wrist strap around your uncovered wrist when handling the plug-in units of the MU!
CautionsDN00204118 © Nokia Corporation 19 (22)Issue 3- 0 en Nokia Proprietary and ConfidentialThe 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.Figure 7. Electrostatic sensitive device labelElectrostatic 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.
