VTS Series 1500Watt 11 True Sine Wave Inverter/AC transfer Switch

6. DC Wire and Fuse Sizes:

Use the following DC cable and inline fuse sizes. DC cables should be as short as possible (ideally less than 10

feet, never exceeding 20') and large enough to handle the required current in accordance with the electrical codes

or regulations applicable to the installation. DC cables that are too small or too long will cause DC voltage drop

which will result in deteriorated inverter performance such as poor surge capability and frequent low-input voltage

warnings and shutdowns.

6.1. DC Connections:

When ready to connect DC cables, connect battery positive (+) to inverter positive then connect battery negative (-)

to inverter negative. Be aware, there will be a large spark when the last DC connection is made. This is

normal.

Never connect inverter positive to battery negative.

Be very careful to NEVER connect DC

terminals to the inverter backwards. Reverse polarity connection may cause permanent damage to the inverter.

Torque the DC terminal bolts to 9 -10 ft-lbs.

WARNING: Loose DC connections will overheat and cause a fire

WARNING: To protect the DC cables, and to protect the inverter if positive and negative are reversed, a DC fuse

must be installed in the positive inverter cable within 18” of the battery. Failure to place a fuse in the inverter positive

cable will void the warranty.
