2.6.2. Connecting the Power Harness to the Battery
The power harness uses a pair of 14 AWG power wires to connect to the vehicle
battery. See Figure 2-6.
The supplied in-line automotive fuse holder is for protecting the red positive (+)
battery wire. A 10 A fuse and in-line fuse holder is supplied for the red positive
(+) battery power wire.
To connect the power harness to the battery:
1. Connect the black negative (–) battery power wire to the battery’s negative
(–) terminal. If there is a master battery switch in the battery compartment
connected to the battery’s negative (–) terminal, then connect the black
negative (–) battery power wire after the battery switch.
2. The in-line fuse holder consists of a black plastic piece with an attached cap
that simply pulls apart. Install the 10 A fuse and push the holder back
together.
3. Strip the red wire end appropriately. A butt splice connector is supplied to
connect the fuse holder to the red battery power wire. Connect the other end
of the fuse holder directly to the battery’s positive (+) terminal.
2.7. Step 6: Installing the Smart-Link™ Module
The EX8 Plus DVR uses the external Smart-Link module to provide interface
connections to a variety of different signals. See Figure 2-8.
The Smart-Link is designed to be installed into the electrical compartment of a
vehicle, reducing the number of cables that connect to the DVR and reducing the
lengths of interface harnesses and cables that connect to the vehicle systems.
If you need assistance in determining a suitable location to mount the Smart-Link,
contact Customer Service at Seon Design. (The dimensions for the Smart-Link are
provided in “A.5. Smart-Link™ Module” on page A–4.)
To install the Smart-Link module:
1. Mount the Smart-Link on a vertical surface to avoid having liquids pool on
the bottom.
2. Mount the Smart-Link using the four #10 × ¾" sheet metal screws or the four
#10 × ¾" self-drilling screws.
3. Verify that one end of the Smart-Link-to-DVR connection harness is
connected to the
POWER
IN
connector on the back of the DVR. The connectors
on the harness are identical so either end can be plugged into either device.
Important:
Connecting the power farther from the battery results in a larger voltage
drop (reduced voltage from the battery to the DVR). If the voltage drop is too large, then
the DVR detects the low voltage and stops recording to protect itself. If the voltage stays
low for too long, the DVR interprets this as meaning the vehicle battery is drained and the
DVR shuts down completely.
