1.7 POWER SUPPLY
Vehicle power input for the Rhino-NET™ can range from 11 to 60VDC and is accepted
without the need to perform any adjustments within the Rhino-NET™.
If 11 to 60V DC power is not available – for example, in an office environment – an optional
external FP18 Power Supply can be used to convert AC wall power to an appropriate DC
level.
Power input is protected by an externally accessible fuse.
1.7.1 Backup Batteries
There are two backup batteries; one for the internal clock and the other for volatile memory
data backup.
A small internal Lithium (Li) backup battery (button type) provides power to the internal clock
when the primary power supply has been depleted, removed or has failed. This battery is not
rechargeable and requires no user intervention other than periodic replacement.
Replacement is performed by authorized personnel only. The average duration of the backup
battery is 3 years.
A larger Lithium (Li) rechargeable backup battery maintains data stored in volatile memory
(RAM) when the power supply is removed. A fully charged backup battery can maintain data
for approximately 5-7 days under normal ambient temperatures. Since the battery is not
charged at the factory, when using Rhino-NET™ for the first time, it is suggested to connect
the power source to the terminal (with the power switch off) for at least 8 hours to charge the
battery. The battery charging will be done whenever Rhino-NET™ is connected to a power
source, even if it is not running. The best temperature range for correct battery charging is
between 10 °C and 45 °C. At the extreme temperature ranges, less than 0 °C or more than
45 °C, the battery will not be charged. If during the charging phase, any anomaly is
encountered, a ‘backup battery failure’ message will be displayed.
WARNING
Do not incinerate, disassemble, short terminals or expose to high
temperature. Risk of fire, explosion. Risk of explosion if the battery is
replaced by an incorrect type. Dispose of the batteries as required by the
relevant laws in force.
