The entire system should be protected by the use of appropriately rated fuses in the
power supply.
Note: It is particularly important when the prime power source is a battery that fuses be
employed in all the supply lines.
Warning: Fuse – DC powered Base Stations
The cable supplied for connecting a DC power source such as a battery to
the backplane of the SL2 Base Station, includes a fuse. This fuse is critical
to the IEC 60950 safety compliance of the T800 SL2 Base Station and must
be used or compliance will be voided. If the fuse has blown it must be
replaced with the same component
The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A
(60V
AC
)
1.4 Reverse Polarity and Overvoltage Protection
A crowbar diode is fitted to all T854 transmitters for protection against connection to a
power supply of incorrect polarity. It also provides overvoltage protection from voltage
transients caused by lightning strikes.
Note: A fuse must be fitted in the power supply line for the diode to provide effec-
tive protection.
