How To Make A Cable To Mimic A NEMA Cabinet

Parts needed:

• Amphenol A71-627118-55P-ND
• DB-15 male connector
• Power cord
• Wire and wire nuts

1. Take the Amphenol A71-627118-55P-ND and solder the power cord to the pins shown in Table 1.
   • To make the monitor run with no faults, tie the pins n and m to pin T. (See Table 2)
   • If you want a Type 2 cabinet (16-phase), tie pin HH (Type Select) to Logic Ground. For a Type 1(12 Channel) Cabinet, leave the pin HH (Type Select) open (floating). You can use a toggle switch to make pin HH (Type Select) a selectable.
2. Solder a wire to each pin shown in Table 2 and wire nut them together. This applies a logic TRUE (low) state to this input of the +24V Monitor Inhibit, Controller Voltage Monitor, and Type Select. If you do not apply a logic TRUE (low) state to these inputs the monitor will go to a failed state.
   • Once you complete Step 1 and 2 you will be able to power up the monitor. The monitor will show a PORT 1 FAIL and no field status will be shown on the 2 lower liquid crystal displays (R Y G). However, you will be able to go through the Status and Menu Screens. To override the PORT 1 FAIL, see next step.

3. Take the DB-15 male connector and solder a jumper wire to pins 2 and 10
   • Once you complete Step 3, put this DB15 into the PORT 1 SDLC of the monitor and reset the monitor. The Port 1 Fail and Fault Led will clear
