|
UNINTENDED EQUIPMENT OPERATION |
|
oAdapt the programmable filtering to the frequency applied at the inputs. oUse shielded cables wherever specified, connected to the functional ground using the TM2XMTGB grounding bar. oUse a specific 24 Vdc supply for inputs and outputs. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
This illustration presents the fast outputs wiring diagram:
* Use a type T fuse appropriate for the load, not to exceed 2.5 A
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Ensure that the physical wiring respects the connections indicated in the wiring diagram. In particular, that the 24V terminal is connected, only 24 Vdc is connected to the 24V terminal, and only 0 Vdc is connected to the 0V terminal. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
