Solar Converters EQ 12/24-50 Manuals

dwg# i-8007 Page 1 MANUAL Model: EQ 12/24-50 Solar Converters Inc. - Rev. B IMPORTANT NOTE: Unit is bi-directional in its operation. Please take a moment to ensure the input and output voltage required and the direction of the power flow. Misconnection or backwards connection of the unit may provide either half the voltage or twice the voltage to the load, with potential damage to the load and/or unit. Warning: This unit may operate from multiple hazardous energy sources. Ensure that all power sources are inactive before making any connections to this unit. Ensure proper procedures and the appropriate electrical codes are followed. To be serviced only by qualified personnel. Warning: Ensure the battery is disconnected and/or safe operating procedures are followed when making battery connections. Extreme care must be taken to ensure the battery is not shorted. Make sure all strands are inside their respective terminals. Qualified personnel only to connect and service this unit. START HERE Section 1 Please determine if a step down, step up or battery equalization function is required. - If the load voltage is 1/2 the input voltage = step down. Go to Section 2 - If the load voltage is twice the input voltage = step up. Go to Section 3 - If used to equalize battery voltage to account for battery voltage mismatch, used as both step up and step down. Go to Section 4 NOTE: FUSING REQUIRED ON BOTH HIGH AND LOW WIRES Section 2: Step Down Transformer Input Voltage: 10.5 - 32 DC volts Current: 0 - 25 amps nominal Output Voltage: 5.5 - 16 DC volts = 1/2 input voltage Current: 0 - 50 amps continuous 2.1 Common Connection Using wire of sufficient amperage for the load connection (#12 AWG or better) connect the negative of the battery and the negative connection of the load to the COM Terminal. 2.2 Load Power Connection Using a wire of sufficient amperage for the load power (#12 AWG or better) connect the positive of the load to the LOW Terminal. 2.3 Input Power Connection Using wire of sufficient amperage for the input connection (#12 AWG or better) connect the positive of the battery to the High Terminal.
