6. INSTALLATION GUIDE
The following recommendations must be followed closely before starting up the
BSR75 module.
6.1. LOCATION
The BSR75 has been designed in the standard format of 19” / 3 units high and it
must be installed in cabinets with this format.
The BSR75 site must be permanent, well-ventilated and without vibrations.
6.2. POWER SUPPLY CONNECTION
DC power supply: check that the power supply source and/or the battery to be
used meets the voltage and current requirements necessary to supply the equipment:
 Nominal voltage: 26.4V
DC
(range: from 21.12 to 31.68 V
DC
).
 Minimum source current: 20 A.
 There is a power control circuit in the RPS75 module in order to avoid an over-
current condition.
 If lead batteries are used, they are to be placed as far from the BSR75 as
possible to prevent corrosion in the repeater due to battery vapours. They
should be situated in a well-ventilated place.
 Use the power supply connector provided (D013000) to connect the BSR75 to
the power supply source. Use a cable with 2.5 mm
2
minimum diameter (or
AWG-12). Ensure that the connection is made with the correct polarity.
 Ensure that the earth connection is made. Make this connection with a cable of
maximum diameter and minimum length.
NEVER use a gas or electricity conduit as an earth.
