2 General Information
2.1 General Safety Instructions
● This document is an integral part of the K-BOW system platform2.
● Read all K-BOW documentation completely, especially
– before installing a K-BOW system platform2,
– before the rst start-up,
– before operating a system,
– before performing any changes,
– for regularly refreshing your knowledge about it.
● Keep the K-BOW documents for reference throughout the life of the system. Pass the
K-BOW documents on to the next owner and user of the system.
● Read the installation instructions before starting the installation.
● The system documentation must always be available at the installation location.
Thesystem documentation comprises at least the following documents:
– K-BOW Platform2 Safety Instructions – K-BOW Platform2 Operation and
Maintenance
– K-BOW Platform2 Installation Manual
– K-BOW Platform2 System Description – K-BOW Setup Manual
● Always perform the measures described in the K-BOW documents in the sequence
speci ed.
● Do not replace any modules, especially the PA module and duplexer module onsite.
● The K-BOW equipment is intended to be earthed. Ensure that the racks are connected
to a protective earthing conductor during normal use.
● When installing a K-BOW system, always connect it to a protective earthing conductor
rst and disconnect it last.
● The K-BOW system relies on the building installation for short-circuit (overcurrent)
protection. Ensure that the protective device is rated in accordance with the con gured
K-BOW system.
●
When installing the K-BOW system, comply with local and national electrical codes.
● Normal use of the system will not damage the base station; however, with the increase
of RU during network coverage for indoor distribution, additive uplink noise resulting
from the use of many RUs may affect the sensitivity of the base station, which should
be considered during engineering design.
● While bre optic power levels used in this system are very low, it is advisable to avoid
exposing the human eye to the laser light emanating from a bre port or plug.
● Prior to upgrading and plugging in units and parts, rst disconnect the standby battery
and power source.
● Signals coupled from the BTS shall be no greater than +15 dBm, otherwise the device
will not operate normally and damage may occur to the circuit.
● Around the devices including their radiation ns, the safety clearance stated in
Chapter 3.2.2, p. 19 must be complied with. Otherwise the device temperature may rise
and affect the service life of the device.
