6. Guidelines on fault clearance
There can be dangerous voltages at the following connections:
• At all supply module connections and associated transformers, capacitors
and additional bleeders. In particular, at the power connections (terminal
X9), control voltage input X10, and the blower supply connections X13 and
X14.
• At the drive modules, motors and the plug-in connectors of the motor.
Before working on electrical devices:
Use the mains disconnect to cut power to the entire installation.
Make sure it cannot be switched back on!
Wait for the DC bus to discharge. Depending upon the DC bus
capacitors, discharge can take several minutes. Verify voltage by
measuring it at X9 (L+/L-).
Do not run motor. The motor connections are energized during any
movements of the motor!
Before switching on:
Do not turn on power until the touch-cover shipped with each unit
has been installed!
To avoid damage to the machine, note:
The initial start-up should only be performed by trained personnel.
Make sure that the E-stop and the axis limit switches are operational.
Before switching on:
Make sure the circuitry agrees with the KDV terminal diagram and
electrical schematics for the machine.
Electrostatic loads are hazardous to electronic components. Therefore:
Ground all objects prior to contact with the units.
