Installing an MX2010 Three-Phase Wye AC Power Cord
To install a three-phase wye 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 all the power switches on the PSM faceplates to the off (O) position.
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 metal wiring compartment.
9. Screw the retaining nut onto the AC power cord to secure it to the metal wiring compartment.
