Section 2: Installing the 20-1000TUL
Unpacking the Inverter
Inspect the shipping container and equipment for loose or damaged parts.
`
If any damage is found, immediately notify the freight carrier.
Installing the Inverter
Step 1: Turn the inverter OFF/disconnect power to the wiring harness.
Make sure power to the vehicle wiring harness is disconnected. Verify
that the inverter is turned OFF by checking that the ON-OFF/RESET
Inverter Switch is in the OFF-RESET position.
(The button should NOT be pushed in.)
Step 2: Select a location for the unit.
An ideal installation location has the following characteristics:
• Close to the battery (within six feet using #2 AWG wire)
• Protected from the weather
• Well ventilated
Step 3: Route DC input cables.
Route the negative and positive DC input cables from the inverter (through
the quick connector) to the battery. If required, protect cables where they
contact hard, sharp edges.
Step 4: Install in-line fuse.
Install an in-line Bussman ANN 125 or equivalent fuse (Vanner p/n 03640-
fuse and 03637-fuse holder) in the red, positive DC input cable between the
battery and inverter, within 18 in. of the battery or DC wiring bus system.
Step 5: Connect Bonding Lug.
Use a AWG #8 or larger copper conductor to connect the chassis bonding lug
to the vehicle chassis and/or earth ground.
Step 6: Connect the inverter to the battery.
Connect the black, negative DC input cable from the quick connector to the
battery negative (-) terminal. This battery negative terminal is usually where
the battery negative connects to the engine block or frame.
Connect the red, positive DC input cable from the quick connector to the
fuse of the battery positive (+) terminal. This battery terminal is usually
connected to the DC electrical system at the load side of the Battery
Disconnect Switch.
