DIB-500 R4.1 Requirements concerning the operation room
Grounding and overvoltage protection
28 Site Requirements 90DIB500R41SR_FCC02 – 99.1
The applicable standards and guidelines for the ambient conditions of the product are
set forth in Table 4.5 on page 26.
4.3 Grounding and overvoltage protection
The following chapter describes the requirements for the grounding and overvoltage
protection of the site/operation room to ensure that the product can always be used as
intended.
The applicable national regulations / the applicable regulations of the respective country
of use shall apply for the grounding and the overvoltage protection.
The cross-section of the earthing conductor must be at least 6 mm
2
. These earthing
conductors must comply with the requirements of DIN VDE 0100 Part 540 (IEC 60364-
5-54). According to DIN EN 62305-1 (VDE 0185-305-1), potential equalisation must be
installed between the lightning protection system and the electrical system.
Standards and Guidelines
Possible as the case may be required measures for the installation of earthing and
bonding appliances of telecommunications equipment can be found in ETSI EN 300
253 V2.1.1.
4.3.1 Overvoltage protection of the equipment rack (V
AC
/V
DC
)
Each equipment rack (apart from the equipment rack(s) of the cavity variant) of the
DIB-500 R4.1 features a connection panel, via which the integrated components are
supplied with voltage and grounded.
The protective ground connection of the voltage supply connector of the equipment rack
is not a sufficient protection of the system against pulse voltages, such as those that
occur during a thunderstorm.
For this reason, the equipment rack must be protected against overvoltages at the
installation site through appropriate grounding equipment to prevent damage to the sys-
tem technology.
Responsibility for the installation, commissioning and maintenance of a ground-
ing and overvoltage system
The operating company is responsible for the proper installation, commissioning and
maintenance of an appropriate grounding and overvoltage system, unless this is an
integral part of the contract concluded with Rohde & Schwarz Professional Mobile
Radio GmbH. It is advisable to obtain the opinion of an expert and to implement the
safety measures accordingly.
