Product Description
Introduction
This manual contains information and procedures for installation, operation, and maintenance of a High Power
Wideband Radio Head (WRH-V). The manual is organized into chapters as follows:
Scope of Manual
This manual is intended for use by service technicians familiar with similar types of equipment. It contains
service information required for the equipment described and is current as of the printing date. Changes which
occur after the printing date may be incorporated by a complete manual revision or alternatively as additions.
Safety
It is necessary that any personnel involved in installation, operation, or service of units included in a Powerwave
Distributed Antenna System (DAS) understand and follow the below points.
❑ Powerwave WRH-Vs are designed to receive and amplify signals from one or more
base stations and retransmit the signals to one or more mobile stations. And, also to
act the other way round, that is to receive signals from one or more mobile stations,
amplify and retransmit the signals to the base stations. Powerwave WRH-V systems
must be used exclusively for this purpose and nothing else.
❑ Units supplied from the mains must be connected to grounded outlets and in conformity
with the local prescriptions.
❑ Power supply units supplied from the mains contain dangerous voltage that can cause
electric shock. Disconnect the mains prior to any work in such a unit. Local regulations
are to be followed when servicing such units. Authorized service personnel only are
allowed to service units while the mains is connected.
❑ The WRH-V cover must be secured in opened position, for instance by tying it up.
Otherwise, the cover can be closed by the wind and cause your fingers getting pinched
or your head being hit.
❑ When working on a WRH-V on high ground, for instance on a mast or pole, be careful
not to drop parts or the entire WRH. Falling parts can cause serious personal injury.
❑ All RF transmitting units, including WRHs, will generate radio signals and thereby give
rise to electromagnetic fields that may be hazardous to the health of any person who is
extensively exposed close to an antenna.
❑ A lithium battery is permanently mounted on the CU and FON PCBAs. Due to the risk
of explosion, this battery must only be removed from the board by a Powerwave
authorized service technician.
❑ NiCd batteries are mounted on the FON PCBA. These batteries contain environmental
poisonous substances. If replaced, the old batteries should be disposed of as stated in
the local prescriptions.
