plug adapter can be cut off and used to make connections to the charge base. When mounting in any
vehicle, please have product professionally installed to prevent any safety hazards, personal injury and
possible damage to vehicle or product. The positive lead wire from a 12-24 VDC source must be
connected to the center terminal of the co-axial jack. The negative lead wire from the 12-24 VDC source
must be connected to the center terminal of the co-axial jack. It is recommended that a 5 amp, time
delay fuse be connected in a series to the positive lead of the DC power supply before the co-axial jack.
