Chapter 12 - Replacing Printed Circuit Boards
1
Deenergize and ground the ACS 6000.
Danger: The ACS 6000 is a high voltage device.
Make sure that the cabinet has been completely deenergized and that
power cannot be applied by accident.
Failure to do so may result in injury or death.
Note: After switching off the mains and after the motor has come to a stop,
allow the DC link capacitors to discharge. The light GND.- SWITCH
UNLOCKED must be on, before grounding the ACS 6000.
2
Switch off the auxiliary power supply. Refer to the wiring diagrams to
identify the circuit breaker.
Note:
Do not touch printed circuit boards or other sensitive components
without applying static-sensitive handling precautions!
Static electricity can damage boards and components!
•
Do not touch the components without wearing a properly grounded
wrist.
•
Put the board or component on a grounded working surface protected
against electrostatic discharges.
•
Hold a board only at the edge.
•
Handle a faulty board as carefully as a new one.
Note:
Handle fiber optic cables with care.
Do not touch the ends of the fibers, they are extremely sensitive to dirt.
Always hold the connector when unpluggung a fiber optic cable.
Fiber optic cables can be damaged if bent sharply. Observe the minimum
bend radius of 25 mm.
