Measuring the In-
termediate Circuit
Voltage
WARNING!
Danger of electric shock! Despite the presence of a discharge circuit, a dangerous
level of voltage can still be present in the intermediate circuit for a long time.
In order to ensure a safe work environment, wait for the discharge time to elapse and then
measure the intermediate circuit voltage with an appropriate measuring device. The volt-
age must not exceed 30 V DC. The measuring points are illustrated in the following images.
