BRU3 MANUAL, Doc.no: 124 46-ANNA 805 08 Uen Rev G, 2003-06-10
4 Precautions
4.1 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.
4.2 Grounding
DANGER!
Grounding must be done before the “MAIN SWITCH” on the FE Power Supply
Unit (FPU) is switched on. Before operation of the BRU3, ensure that the BRU3
is grounded in accordance with the Installation Instructions.
4.3 Radio Frequency Exposure
BRU3 base stations are typically mounted in areas not available to general
public. Applicable distances for RF exposure assessment will in praxis exceed
the radio frequency near-field range. Thus, the specific absorption rate does not
need to be considered, unless radiating parts of the installation are located closer
than one meter to areas accessible to general public.
DANGER!
The BRU3 is marketed without antenna. Every installation of a BRU3 must
maintain safety distances between radiating parts (for example, the antenna)
and general public in order to meet applicable radio frequency exposure
requirements under all circumstances of normal operation and service work
being performed.
BRU3 installation, and antenna connection should be performed only by
professional personell, with suitable qualification to assess potential radio
frequency hazards. BRU3 output power, duty cycle, feed-line loss, combiner
loss and antenna characteristics shall be considered.
