 The **V+** and **GND** pins power both the LED and the control chip. A separate screw clamp terminal is also provided for a direct power connection, which is recommended to avoid problems caused by voltage drop along a chain of modules. The outermost **+** and **-** terminals should be connected to the main power supply bus. ShiftBars require up to 450mA per module when all LEDs are active. The supply voltage should be kept between 5.5 and 17 volts, depending on requirements of the attached LEDs. The **V+** and **GND** pins power both the LED and the control chip.

 +**As is true of most digital electronics, if you connect power backwards or short contacts with metal objects or other modules on the chain, you WILL destroy the logic chip. Please triple-check all cables and make sure the modules are not in contact with anything conductive BEFORE applying power.**
