STEP 5 – INSTALL CABLES
The P
ANTHER
300M Mobile Radio is installed as a front mount radio. The
location of the mount, the application, and the options to be installed should
be considered when planning the cable runs. The cable diagram in Figure 1
should be referenced throughout the installation process.
Power Cable
The power cable RPM 113 7674/10 consists of a two-wire cable, see Figure
6. The red fused lead supplies power to the radio directly from the vehicle
battery. Ignition Sense lead, through the separate option cable, is used by
the radio electronics to determine when the ignition switch is turned on.
The black lead is the radio ground connection.
To install the power cable:
1.
Remove the fuse from the power cable.
2.
When the power cable is wired directly to the vehicle’s battery, it is
necessary to route the red power lead through the vehicle’s firewall. If
an existing hole is not conveniently located in the firewall, drill a 1/2-
inch hole in the firewall for the cable run and insert a rubber grommet.
This grommet is required to prevent lead chaffing. Additional
grommets may be required if the leads must pass through shields or
guards in the engine compartment.
