Page 3: Introduction
SAFETY INSTRUCTIONS 3 (30) Introduction This section contains Safety Instructions for handling the MOBITEX Base Radio Unit 3 (BRU3) during installation and maintenance work. Please read the Safety Instructions before starting any kind of installation or maintenance work. BRU3 MANUAL, Doc.no: b3saf_en Uen Rev PH1, 2003-10-20... -
Page 4: Safety Instructions
Read and follow all warning notices and instructions found on the product or included in the BRU3 manual. Ericsson takes no responsibility if the labels have disappeared from a BRU3 due to accident or age. Where local regulations exist, these are to be followed. The safety information in this manual is a supplement to local regulations. -
Page 5: Definition Of Expressions
SAFETY INSTRUCTIONS 5 (30) Make sure that the FE Power Supply cable is not squeezed by anything and do not place the cable in such a way that there is a risk of people treading on it. General purpose cables are provided with the BRU3. The provision of special cables, which may be required by a regulatory inspection authority for the installation site, is the responsibility of the customer. -
Page 6: It Power System
6 (30) BRU3 MANUAL IT Power System The BRU3 is not intended for use in an “IT power distribution system”. Type approval testing in accordance with EN60950, UL1950 and CSA 22.2 No. 950 has been performed excluding IT-systems. An IT power system is a power distribution system having no direct connection to earth, only the exposed conductive parts of the electrical installation are grounded. -
Page 7: Precautions
SAFETY INSTRUCTIONS 7 (30) Precautions High Voltage DANGER! The BRU3 is powered by 120 or 230V AC. During normal operation, live terminals or components are not accessible. If the BRU3 front cover is opened during operation, for maintenance or commissioning purposes, live terminals or components are exposed. - Page 8 8 (30) BRU3 MANUAL The product is marketed without antenna and it is to be installed by professional personnel. The installation manual contains a warning note requiring the installation responsible to maintain an antenna safety distance from general public to meet RF exposure limits, considering feeder loss and antenna gain in every case.

Page 9: Poisonous Substances
Do not short-circuit. The battery pack may cause burns. • There is danger of explosion if the battery pack is incorrectly replaced. Replace the battery pack with the same type recommended by Ericsson. • Return used batteries to Ericsson. In the future the label in Figure 2 will mark the metallic shield covering the battery pack inside the BRU3. - Page 10 10 (30) BRU3 MANUAL Refer to Figure 3 for the different parts of the BRU3: 1 = FE Case Bottom Frame (FBF) 2 = FE Power Supply Unit (FPU) 3 = FE Battery Unit (FBU) 4 = FE Mains Power Cable Figure 3 Base Radio Unit 3 (BRU3) Unlock and open the BRU3.

Study these instructions carefully before starting work with the BRU3 to reduce the risk of accidents. If questions arise regarding the safety instructions, contact the supervisor or the local Ericsson company. Follow existing local regulations. The safety information in this manual is only a supplement to local regulations. -
Page 12: Grade Of Toxicity
12 (30) BRU3 MANUAL 5.2.2 Grade of Toxicity Beryllium Oxide dust is very dangerous if inhaled, even for only a few seconds. It may cause injury to skin or mucous membranes severe enough to endanger life or cause permanent injury. Particles penetrating the skin through wounds or abrasions are liable to cause chronic ulcerations. -
Page 13: End Of Life Treatment
