The external alarms are defined at the installation. Instead it is located almost at the edge, facing towards the centre of the cylinder. For maintenance work, a clear space of at least 1, mm in front of the cabinets and racks work is recommended. Table 8 on page 12 shows an example for a typical antenna. The transmission equipment is then provided with power longer than the RBS. The alarm device connected to the screw terminals should be isolated relay contacts.

Click here to sign up. To ericsso out more, including how to control cookies, see here: Fans The fans must be inspected and cleaned if necessary every year. For further information on calculation methods, see Radio Frequency Electromagnetic Fields.
All the files are without file extensions and on a FAT formatted file system. Number of units per cabinet per cabinet: The figures show test points and the tables show the noise dispersion generated by a free-standing RBS with three fans and by an RBS mounted against a wall. Proudly powered by WordPress. The resulting dimensions, in metres, for a compliance boundary for both public and occupational exposure are shown in Table 8 on page Deviations from these values can be experienced due to the nature of materials in the environment where the cabinet is installed.
Adam Mizban December 24, at The RBS supports two transmission standards: External connectors and operator interfaces are located on the corresponding hardware units. For more information about the operator interface, see Optical Indicators and Switches. All units in the cabinet are easily accessible from the front of the cabinet, which means that the cabinets can be mounted side by side or with their backs against a wall.
The acoustic noise dispersion values for a free-standing cabinet and a cabinet installed against a wall were tested according to the ISO standard. The battery fuse unit has two large connectors for the battery and some other external unit that I am not sure what is. Number of units per cabinet: Ericsson shall have no liability for any error or damage of any kind resulting from the use of this document.

The figures in the table have been rounded up or down to the nearest 0. Expansion cabinets and racks can be positioned to the left or to the right of the master cabinet. The CF card contains 91 files and 2 sub folders with a total of There is some trimpots in the middle of the PSU when you have the plate and heat sink removed, the one sitting closest to the middle of the group of three is able to adjust the output voltage, so it is possible to set it up to just about The compliance boundary is defined as a cylinder around the antenna.
The erisson cover protrudes 77 mm in front of the cabinet.
The RBS cabinet contains the radio equipment, power supply, and the climate equipment fans. The DRU can be configured as either combined mode or erifsson mode.
Andrew Villalpando December 24, at This site uses Akismet to reduce spam. In reality the occupational compliance distance by the side, in line with the front of the antenna, is less than 0. Log In Sign Up. However, expansion to the right is recommended in order to follow the same standard globally.
Notify me of follow-up comments by email. The voltage between terminals with an open contact is 24 V DC. The contents of this document are subject to revision without notice due to continued progress in methodology, design and manufacturing. Each distribution circuit in the 22116 is connected to a IDM circuit breaker. The product is marked with the CE and FCC symbols to indicate compliance with the legal requirements of the region.
The distance between the rear of the antenna and the edge of the cylinder is the Distance behind antenna. All the files seems to be written in some high level machine code as I can not interpret it.

The optional transmission equipment used is: As the antenna field distributions will differ, complete calculations or measurements may be necessary to fricsson the compliance boundary for other configurations chosen by the customer. Overvoltage protection for external alarm cables. Sorry, your blog cannot share posts by email.
External transmission equipment can be supplied from the battery cabinet.
In the event of AC power failure, the batteries deliver the necessary power to the radio cabinet as well as to the transmission equipment, if used. Their estimated lifetime is at least 10 years.
Power can be connected to the base station in two ways: Ericsson has performed a free-space near-field RF exposure assessment of typical configurations of the RBS with a recommended antenna.
