Connecting the Auxiliary Power Cable (J4)
Connect the auxiliary power supply to the J4 port on the front of the Bassoon, using a
2-pin Molex plug. Remember, you are working with DC power; be sure to exercise caution. The
required voltage is 24 VDC.
Notes for 24 VDC auxiliary power supply connections:
•
Use a 24 or 26 AWG twisted pair shielded cable.
•
The 24 VDC auxiliary power supply must meet all safety requirements and must be
separated from hazardous live voltages using reinforced or double insulation in accordance
with approved safety standards.
•
For safety reasons, connect the return (common) of the 24 VDC source to the closest
ground.
•
Connect the cable shield to the closest ground near the 24 VDC source.
•
Before applying power, first verify the polarity of the connection.
