3.5.3. Special Note about Disconnecting Molex Connectors
The Auxiliary Power Cable (J4), the Feedback cables (J2 and J3) and the I/O cables (J5, J6 and J7)
all use 2 mm pitch Molex connectors. These connectors snap together quite easily, but require
a small standard screwdriver for disassembly.
To disassemble the Molex connector:
1. Slip the screwdriver into the lock: The lock disengages.
2. Twist the screwdriver downward with light pressure on the handle (see the figure below).

3.5.4. Connecting the Auxiliary Power Cable (J4)
Connect the auxiliary power supply to the J4 port on the front of the Harmonica, 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, 26 or 28 AWG twisted pair shielded cable. The shield should have copper braid.
• The source of the 24 VDC must be isolated.
• 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.
