This option requires DC/DC external power supply Honeywell Part no. VX89303PWRSPLY.
Caution:
For installation by trained service personnel only.
Caution: For proper and safe installation, the input power cable must be connected to a fused circuit on the vehicle. This
fused circuit requires a 10 Amp maximum time delay (slow blow) high interrupting rating fuse. If the supply con-
nection is made directly to the battery, the fuse should be installed in the positive lead within 5 inches of the battery
positive (+) terminal. Note: For North America, a UL Listed fuse is to be used.
Caution:
The VX89303PWRSPLY power supply is sealed per IPXX. Usage in areas where moisture can affect the power
supply connections should be avoided. The power supply should be mounted in a dry location within the vehicle or
placed in a suitable protective enclosure.
