Configuration (continued)

Connect Battery Temperature Sensing Cable—OPTIONAL

The battery temperature sensing function prolongs battery life by adjusting the charge float voltage level based on battery temperature. Connect the sensor cable (the cable, included with select models, has an RJ style connector on one end and a black sensor on the other) to the RJ style jack located on the side of the Inverter/Charger labeled “Remote Temp. Sense.” With user-supplied electrical or duct tape, affix the sensor to the side of the battery below the electrolyte level. Make sure that nothing, not even tape, comes between the sensor and the side of the battery. To guard against false readings due to ambient temperature, place the sensor between batteries, if possible, or away from sources of extreme heat or cold. If the sensor cable is not used, the Inverter/Charger will charge according to its default 25º C values.

Utilize Automatic Generator Starter Capability—OPTIONAL			Pin Configuration
All models except 612 models include an RJ type modular jack on the side panel labeled “Generator Start”. Attach to	1	2	2	- Common

battery voltage levels are low (11.6 VDC) and switch it off when battery voltage levels are high (14.1 VDC).

Ignition Interlock Control function (optional): This function automatically disables (turns OFF) AC power output from the Inverter/Charger when the vehicle’s ignition switch is placed in the “Engine Run” position. This function will satisfy local codes and requirements concerning video monitors or TVs that are located within a driver’s view by automatically turning them off when the engine is started.

Battery Selection

Select Auxiliary Battery Type (if any)

Select “Deep Cycle” batteries to receive optimum performance from your Inverter/Charger. Do not use ordinary car or starting batteries or batteries rated in Cold CrankingAmps (CCA). If the batteries you connect to the Inverter/Charger are not true Deep Cycle batteries, their operational lifetimes may be significantly shortened. If you are using the same battery bank to power the Inverter/Charger as well as DC loads, your battery bank will need to be appropriately sized (larger loads will require a battery bank with a larger amp-hour capacity) or the operational lifetimes of the batteries may be significantly shortened.

Batteries of either Wet-Cell (vented) or Gel-Cell /Absorbed Glass Mat (sealed) construction are ideal. 6-volt “golf cart”, Marine Deep-Cycle or 8D Deep-Cycle batteries are also acceptable. You must set the Inverter/Charger’s Battery Type DIP Switch (see Configuration section for more information) to match the type of batteries you connect or your batteries may be degraded or damaged over an extended period of time. In many cases, the vehicle battery may be the only one installed. Auxiliary batteries must be identical to the vehicle batteries if they are con- nected to each other.

Match Battery Amp-Hour Capacity to Your Application

Select a battery or system of batteries that will provide your Inverter/Charger with proper DC voltage and an adequate amp-hour capacity to power your application. Even though Tripp Lite Inverter/Chargers are highly-efficient at DC-to-AC inversion, their rated output capacities are limited by the total amp-hour capacity of connected batteries and the support of your vehicle’s alternator if the engine is kept running.

• STEP 1: Determine Total Wattage Required

Add the wattage ratings of all equipment you will connect to your Inverter/Charger. Wattage ratings are usually listed in equipment manuals or on nameplates. If your equipment is rated in amps, multiply that numbertimesAC utility voltage to determine watts. (Example: a ¼ in. drill requires 2½ amps. 2½ amps × 120 volts = 300 watts .)

Note: Your Inverter/Charger will operate at higher efficiencies at about 75% - 80% of nameplate rating.

Example

Tools

¼" Drill Orbital Sander Cordless Tool Charger

300W + 220W + 20W = 540W

Appliances

Blender
300W	+

Color TV

140W +

Laptop Computer
100W	=	540W

• STEP 2: Determine DC Battery Amps Required

Divide the total wattage required (from step 1, above) by the battery voltage (12)	540 watts ÷ 12V = 45 DC Amps
to determine the DC amps required.
