HIMA H41q and H51q series programmable electronic systems (PES)

Central module: Before unplugging, the data cable needs to be removed first. Separate it from the bus board using the ejection rod on the module. Before insertion, check the switch and jumper settings.

Power module: Before replacing, check the output voltage of all other power modules.

7.3 Grounding and Electromagnetic Compatibility

To meet CE requirements and ensure electromagnetic compatibility, strict grounding and shielding measures must be taken:

Grounding: The system supports floating or L-grounding operation. The grounding resistance should be ≤ 2 ohms.

Shielding: The shielding layer of the communication data line must be grounded at the single end of the bus user side (such as H41q/H51q). On site cables (sensors/actuators) should use shielded cables and be laid separately from power cables.

Power filter: It is recommended to install the HIMA H7013 power filter at the 24 V DC inlet.
