Removing a T640 Three-Phase Delta AC Power Supply Cord
To remove a three-phase delta AC power supply cord:
1. Switch off the customer site circuit breakers to the power supply 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 removal 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 switch on the power supply faceplate to the standby position.
NOTE: After powering off a power supply, wait at least 60 seconds before
turning it back on.
