DANGER
Electrical voltage can result in death or serious injury.
● Tests may only be carried out on a drive by personnel who are trained in
working with voltages of up to 600 V AC and 1800 V DC.
● Ensure that the drive is grounded correctly.
● Switch off the supply line to the drive before carrying out work on the drive or
on any of its parts.
● Isolate the power supply to the drive before carrying out work on the drive or
on any of its parts.
● After switching off the power supply, wait at least 5 minutes for the capacitor
to discharge completely.
The following devices are required for conducting the tests:
1. Digital multimeter, preferably with a scale for PWM voltage (e.g., Fluke 87)
2. PC with the latest version of STARTER
3. IOP (Intelligent Operator Panel)
Tests without a power supply
CAUTION
Risk of electric current
If the terminals are not accessible externally, do not open the device because you
will be exposed to a great risk and this will invalidate the warranty.
● In this case, contact your local Siemens branch office.
