Power Supply
Vehicle power input for the VX4 is 12V to 60V DC and is accepted without the need to perform
any manual adjustments within the VX4. See the section titled “Installation”, sub-section titled
“Vehicle 12-60V DC Direct Connection.”
If 12V to 60V DC power is not available – for example, in an office environment – an optional
external Universal Input Power Supply can be used to convert AC wall power to an appropriate
DC level. See the section titled “Installation”, sub-section titled “External Power Supply.”
Power input is fused for protection and the fuse is externally accessible. See section titled
“Installation”, sub-section titled “Fuse Replacement for the VX4.”
Backup Battery
The internal 270 mAh Lithium backup (coin cell) battery provides power to maintain the real time
clock when the VX4 is not powered from an external source. The backup battery requires no user
intervention. Replacement must be performed by LXE.
Caution
!
Danger of explosion if battery is incorrectly replaced.
Replace only with the same type or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.
