Tripp Lite PVX700 owner manual Battery Connection, Vehicular Applications

Battery Connection

Connect your Inverter to your batteries using the following procedures:

•Connect DC Wiring: Though your Inverter is a high-efficiency converter of electricity, its rated output capacity is limited by the length and gauge of the cabling running from the battery to the unit. Use the shortest length and largest diameter cabling (maximum 4 AWG or 5 mm) to fit your Inverter’s DC Input terminals. Shorter and heavier gauge cabling reduces DC voltage drop and allows for maximum transfer of current. Your Inverter is capable of delivering peak wattage at up to 200% of its rated continuous wattage output for brief periods of time. Heavier gauge cabling

should be used when continuously operating heavy draw equipment under these conditions. Tighten your Inverter and battery terminals to approximately 3.5 Newton-meters of torque to create an efficient connection and to prevent excessive heating at this connection. Insufficient tightening of the terminals could void your warranty. See Specifications for

Recommended Cable Sizing.

•Connect Ground: Using a 12-18 AWG (1-2 mm) wire, directly connect the Main Ground Screw to the vehicle’s chassis or earth ground. See the Feature Identification

section to locate the Main Ground Screw. All installations must comply with national and local codes and ordinances.

•Connect Fuse: Tripp Lite recommends that you connect your Inverter’s positive DC Terminal directly to a fuse(s) and fuse block(s) within 45 cm (18 inches) of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating listed in your Inverter’s specifications. See Specifications for fuse recommendations. See diagrams below for proper fuse placement.

WARNING!

•Failure to properly ground your Inverter to a vehicle’s chassis or earth ground may result in a lethal electrical shock hazard.

•Never attempt to operate your Inverter by connecting it directly to output from an alternator rather than a battery or battery bank.

•Observe proper polarity with all DC connections.

Vehicular Applications

Your Inverter’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular applications. It is possible to connect your Inverter to the main battery within your vehicle’s electrical system. In many vehicular contexts, the Inverter will be connected to one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible draining of the main battery.
