5. DO NOT feed the voltaje other than 22~30VDC otherwise damage the unit. The input voltage range specified is the
range of the operating voltage.
6. DO NOT switch ON the unit when it is full loaded as it may damage the unit.
7. MUST place the unit at a place of well air ventilation, heat is generated during operation.
8. NEVER touch the heatsink panel during the unit is operating. The heat sink maybe heated up and burn your hand.
9. DO NOT feed a voltage source into the output terminal, it may damage the unit.
10. BE SURE wiring connections otherwise it may damage the unit. Red cable is for INPUT (+) and Black cable is for
INPUT (
−
). Red terminal is for OUTPUT (+) and Black terminal is for OUTPUT (
−
).
Note: The ground (negative polarity, input and output negative polarities are common) of the unit is connected to the
case.
CONNECTION AND OPERATION
1. Switch OFF the unit.
2. Connect the Input Red Cable to positive terminal (+) and the Input Black Cable to negative terminal (
−
) of the 24V
DC Battery (make sure the battery is not empty) firmly.
3. Turn OFF the equipment to be operated and connect the Red (+) output terminal of the unit to the positive (+) polarity
input of the equipment. Connect the (
−
) output terminal of the unit to the negative (
−
) polarity input of the equipment.
4. Switch ON the unit, POWER INDICATOR lights up, then turn ON the equipment to be powered.
5. When the operation is finished, turn OFF the equipment first and then switch OFF the unit.
6. If the power indicador does not Light up or becomes dimmer and the unit has no output voltaje when the battery (no
tempty) is connected and power is ON, the unit may be Ander the condition of overload or overvoltage. Disconnect
the equipment and check the unit for working properly. If the unit work properly, check the equipment that causing
the problem and DO NOT connect the equipment that causing the problem. If the unit does not work properly, send it
back to your dealer for checking and repairing.
