Installation and user instructions

1. Where to install

The inverter should be installed in a location that meets the following requirements:

 Dry – Do not allow water to drip or splash into the inverter.

 Cool – Ambient air temperature should be between -20 and 40 .℃ ℃

 Safe – Do not install into a battery compartment or other areas where flammable fumes

may exist, such as fuel storage areas or engine compartments.

 Ventilated – Allow at least one inch of clearance around the inverter for air flow. Ensure

the ventilation openings on the rear and front of the unit are not obstructed.

 Dust – Do not install the Inverter in dusty environments. This dust can be pulled into the

unit when the cooling fan is operating.

 Away from batteries- Do not mount the Inverter where it will be exposed to corrosive

gases produced by batteries.

2. Installation

2-1. Before installing the inverter, make sure the main switch is in “OFF” position.

2-2. DC Input connection:

 We recommend the DC cable length should be not longer than 6 feet/1.8m, and the

gauge should be at least 4mm

 Crimp the DC cable with the ring terminals which are included in the package of the

inverter, then fasten these to the inverter DC connector with a screwdriver.

 For battery connection, please mind the recommendation of your battery

manufacturer first. We strongly recommend connecting a fuse to the battery. For SI350-

12XXX, we recommend a 50A fuse, for SI350-24XXX, we recommend a 25A fuse.

WARNING: Wrong polarity connection may damage the inverters without the external fuse

protection.
