Installing an MX2008 Three-Phase Delta AC Power Cord
To install a three-phase delta AC power cord:
1. Switch off the customer-site circuit breakers to the PDM being removed. Make sure that the voltage
across the AC power source cord is 0 V and that there is no chance that the cord might become active
during the installation process.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. Switch the power switches on all the PSM faceplates to the off (O) position for any PSMs that are
powered only from this PDM.
NOTE:
After powering off a PSM, wait at least 60 seconds before turning it back on.
4. Using a number 2 Phillips (+) screwdriver, loosen the four screws on the cover of the metal wiring
compartment that protects the AC terminal block.
5. Remove the cover of the metal AC wiring compartment.
6. Unscrew the retaining nut from the AC power cord.
7. Place the retaining nut inside the metal wiring compartment.
8. Insert the wires of the AC power cord through the hole of the retaining nut and rubber grommet.
9. Insert the wires of the AC power cord through the hole of the metal wiring compartment.
10. Connect the wires to the AC terminal block on the three-phase delta AC PDM (see
Figure 194 on page
443). Loosen each of the input terminal or grounding point screws, and insert the
wire into the grounding point or input terminal, and tighten the screw (see
approved AC wire gauge).
