PS150 or PS250 Power Supplies: Does The Polarity Of The Low Voltage Black And Red Wires Matter?

The polarity of the low voltage (15VDC) black and red wires on the PS150 or PS250 power supplies will not matter for the nGWY2 CTRL, nGWY2 GFX, nPOD GFX, and nBRG8.  Connections to these devices are unmarked since these devises are polarity insensitive.

For the nGWY (Version 1), this device is marked as it is polarity sensitive.  + will be the red wire, - will be the black wire.
