CAUTION: Do not connect the inverter and another AC source (such as a generator or utility power) to the AC wiring at the same time. The inverter will be damaged if its output is connected to AC voltage from another source. Damage can even occur if the inverter is switched off. CAUTION: Do not connect the inverter to a load greater than 400 Watts. CAUTION: It is not recommended to operate loads at the maximum rated output for permanent or extended periods of time. For continuous operation (greater than 60 minutes), it is recommended to operate a load 20% less than the inverter maximum output rating. For example, for a 400 Watt inverter, a maximum load of 320 Watts is recommended. CAUTION: Loose connectors result in excessive voltage drop and may cause over heated wires and melted insulation. CAUTION: Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and may permanently damage the unit. Such damage is not covered by the warranty. CAUTION We recommend a main fuse in the battery's positive cable to protect against DC wiring short circuits (external to the inverter). The fuse should be as close to the battery as possible. We recommend a 50 Amp ANL fuse or equivalent. The specific fuse ampere rating should be sized to allow operation of all your DC powered equipment. CAUTION: Remove any jewelry (watch, ring, etc.). Be careful not to short circuit the battery with any metallic object (wrench, etc.). CAUTION: Electrical installations must meet local and national wiring codes, and should be performed by a qualified electrician. WARNING: If you are making a permanent AC connection to the inverter, make sure that the AC wiring steps are performed before any DC wiring is done. (DC hook-up energizes internal components, regardless of the position of the On/Off Switch). Working on AC connections in such a circumstance may result in an electric shock. WARNING: 115 volt AC power is potentially lethal. Do not work on AC wiring when it is connected to the inverter (even if it is switched off) unless the DC power source is physically disconnected from the inverter. Also, do not work on AC wiring if it is connected to another AC power source such as a generator or the utility line. WARNING: You may observe a spark when making the connection because current can flow to charge the capacitors in the inverter. Do not make this connection in the presence of flammable fumes. Explosion or fire may result. Thoroughly ventilate the battery compartment before making this connection. 14 | P a g e
