Operating the PS5-M
5.1 Output Voltage Selection
Before powering a system containing a PS5-M, the output voltage switch (SW1 - Voltage Select) must
be set for the proper output voltage or damage to the system could occur. Do not change the switch
setting while the unit is powered or damage to the system may occur. Set the switch towards the
green AC Visual Indicator for 12V, away from the green AC Visual Indicator for 24V (the PC board is
labeled with the voltage settings).
