Figure 2: TTA Configuration with Secondary Surge Protection Only
CAUTION! Although Secondary surge protection is built into the TTA that
ships from the factory, Navini recommends that the Primary surge protection kit
be purchased and installed, in particular if the equipment is installed in an area
where electrical storms are common. Surge protection devices should be added
in front of the rectifier. Lightning striking miles away from the BTS may cause
an intense electric current traveling on the power and/or backhaul lines and into
the BTS, damaging the equipment.
