DANGER
High voltages
Electrical accidents including electric shock occur when general safety instructions for
working on the device are not observed. Death, serious injury or material damage will
result.
Please note the following information for your safety:
•
Always observe the five safety rules whenever you are carrying out any work on the
device.
•
Always disconnect the equipment before working on it.
•
Leave the covers in place during normal operation and keep the cabinet doors closed.
•
Do not use any instrumentation if you know it is defective or damaged.
•
Secure the main circuit breaker in the OFF position so that it cannot be reconnected, for
example by removing the switch unit when working on a connected motor or the feeder
cable to the motor.
•
Ground the inverter cabinet and chassis units properly to ensure that no accessible
parts of the equipment are energized or connected in any way to a dangerous voltage
source.
•
Use an earthing spider for grounding purposes. Read the information provided in the
section "Safety instructions regarding maintenance and repairs" in "Maintenance and
servicing" in your operating instructions.
•
Wear personnel protective gear such as goggles, ear protection and helmet to protect
yourself against injury.
•
Always follow the national regulations and local specifications when working on the
equipment.
DANGER
DC link capacitor discharge time
After the mains power has been switched off, high voltages still persist in the DC link
capacitors.
These cause death or serious injury if the safety instructions are not observed or if the
equipment is handled incorrectly.
The DC link capacitors require up to 10 minutes (5 minutes for compact units) before they
are discharged to a safe value (< 60 V).
After you have switched off the main power supply, do not touch the device or carry out any
maintenance work or repair work until the discharge time of 10 minutes (5 minutes for
compact devices) have elapsed.
Measure the voltage once the discharge time has elapsed.
