  • Page 28: Load Wiring

    1-4-5. Load Wiring Wire Gauge Before connecting the unit to a power source, the wire considerations gauge must be taken into account. Load wires must be large enough to resist overheating when a short-circuit condition occurs as well as to maintain a good regulation. The size, polarity and length of a wire are all factors in determining if a wire will withstand short circuiting.
  • Page 29 Load Line When using the LSG Series load generator, voltage drop Inductance and voltage generated due to load line inductance and Considerations current change must be taken into account. Extreme changes in voltage may exceed the minimum or maximum voltage limits. Exceeding the maximum voltage limit may damage the LSG Series.

  • Page 30: Load Wire Connections

    Limiting Load Load line inductance can be reduced in two methods. line inductance Method 1 Ensure load wires are as short as possible and twist the positive and negative load wires together. “Twisted pair” will be shown on any connection diagram where the load wires should be twisted together.

  • Page 31: Using The Front Panel Input Terminals

    1-4-7. Using the Front Panel Input Terminals Description The front panel input terminals feature polarity-distinct caps and accept M6 sized crimped terminals. The front panel input terminals on the LSG Series are physically connected to the rear panel terminals. Caution Step Turn the power off from the rear panel or put the unit into standby mode.

  • Page 32: Using The Rear Panel Input Terminals

    1-4-8. Using the Rear Panel Input Terminals Description The rear panel input terminals accept up to M8-sized crimped terminals. The rear terminals come with a load input terminal cover for safety. The front panel input terminals on the LSG Series are physically connected to the rear panel terminals.

  • Page 33: Using The Terminal Cover (Pel -011)

    1-4-9. Using the Terminal Cover (PEL -011) Description The rear panel terminal cover should be used to prevent electric shock. The rear panel terminal covers should always be used when connecting a load to the rear panel terminals. As the front panel and rear panel terminals are physically connected, the terminal cover should also be used as a safety measure when a power source is connected to the front terminals...
  • Page 34 Steps(2/2) Use your thumb to slide the terminal covers shut, as shown in the diagram below. When the top and bottom covers are flush, reinsert the screw that was removed in step 1.

  • Page 35: Using The Terminal Cover (Pel -013)

    1-4-10. Using the Terminal Cover (PEL -013) Description The flexible rear panel terminal cover should be used when the load wiring becomes too thick to be used with the PEL-011 terminal cover. This is especially true when using the load generators in parallel. Like the PEL-013 terminal cover, the PEL-011 is used to prevent electric shock.

  • Page 36: Using The Terminal Cover

    1-4-11. Using the Terminal Cover Description After connection is finished, please lock terminal cover to avoid electric shock when using the frame control terminal. Ensure the power is off, before making any connections to the booster pack. Caution Steps Install the terminal cover as shown in the picture below. LSG-H Series LSG Series 1-4-12.

  • Page 37: Remote Sense

    1-4-13. Remote Sense Description Remote sense can be used to help compensate for long cable length. The longer the cable, the higher the potential resistance and inductance, therefore a short cable is best. Twisting the cable can help reduce induced inductance and using the remote sensing terminals compensates the voltage drop seen across the load leads, especially leads with higher resistance.

  • Page 38: Firmware Update

    The LSG Series allows the firmware to be updated by end- users. Before using the LSG Series, please check the TEXIO TECHNOLOGY website or ask your local distributor for the latest firmware. Before updating the firmware, please check the firmware version and model.
