Note
Internal fans
The internal fans of the HF Choke Module run permanently regardless of the temperature
and whether the pulses are enabled.
Connect the terminals to transfer the temperature signals
The HF line-up does not function without the X21 terminals being connected. Therefore, it is
absolutely necessary that the following terminals are connected with one another to transfer
the temperature signals from the HF Choke Module to the HF Damping Module:
● X21.1 and X21.2 on the HF Choke Module with X21.1 and X21.2 on the HF Damping
Module
● X21.3 and X21.4 on the HF Choke Module with X21.3 and X21.4 on the HF Damping
Module
Use shielded signal cables and connect the cable shields to the supplied shield terminal.
