Figure 34: Connecting a Right-Angle DC Power Cable to a DC Power Supply in a PTX1000
(CBL-JNP-PWR-DSUB3)
WARNING: Ensure that the power cables do not block access to device components
or drape where people could trip over them.
5. Using the slotted screwdriver, tighten the screws on the power cable connector to between 6 lb-in
(0.68 Nm) and 7 lb-in (0.79 Nm).
CAUTION: You must use an appropriate torque-controlled tool to tighten the
screws on the DC power cable connector. Do not overtighten the screws. Applying
excessive torque damages the terminal block and the wiring tray. The absolute
maximum torque that may be applied to this screw is 10 lb-in (1.13 Nm).
6. Repeat Step 4 and Step 5 for each power supply that you are connecting to power.
7. Close the input circuit breaker.
NOTE: We recommend that the 48-VDC facility DC source be equipped with a circuit breaker
rated at 40 A (–48 VDC) minimum, or as required by local code.
