Anti-Condensation Heating - Siemens SINAMICS PERFECT HARMONY GH180 Reference Manual

To avoid accidents, the drive doors must be closed during operation. This is guaranteed by the
electromagnetic door interlocking system. The doors of the power section remain interlocked
until an appropriate safety wait time has elapsed.
Test procedure
1. The auxiliary voltage is present.
2. All drive doors have been closed.
3. The medium voltage is available.
4. The power section doors cannot be opened.
5. The power section power supply is switched off. The safety wait time elapses. The power
6. If a grounding switch is installed, it is closed manually.
7. The selector switch on the drive is set to "OFF". The EMERGENCY STOP is pressed.
Result
The test is passed if the door interlocking system functions as described.

Anti-condensation heating

Fundamentals
A check is made as to whether the anti-condensation heating heats up after switching on. This
prevents the formation of condensation in the drive when it is not operational.
Test procedure
1. The temperature of the anti-condensation heating is measured using an infrared
2. The auxiliary voltage for the anti-condensation heating is switched on.
3. The temperature is measured again.
Result
The test is passed if the anti-condensation heating elements heat up after they have been
switched on.
