User Lines
The port with user lines is located at the rear panel of the rack mount frame (Figure
Table 3-2 User Line Pins
Pin | Name | Function |
1 | User_Ground | All user lines are referenced to user_gnd. User_gnd is |
|
| isolated from both the input DC power and the output AC |
|
| power. |
2 | Shut_Down | This is an input pin. The input impedance is 100 Ω in |
|
| parallel with 20 pF. A logic high (1.25 V to 5 V) would set |
|
| the inverter into Standby Mode (see page |
|
| floating, the internal pull_down resistor of 100 Ω will |
|
| force a logic “0” and this pin becomes inactive. |
3 | Fault_Flag | This is an output pin. A logic high (5 V) indicates that an |
|
| alarm has tripped. The output of the inverter is, therefore, |
|
| disabled. |
4Auxiliary_Line This is an output pin. The functionality of this user line is factory preset. It can be user configured if the Ethernet option is installed.
| 5 Inverter_On | This is an output pin. A logic high (5 V) indicates that the |
|
| inverter is in an “on” state and delivering AC power to the |
|
| AC output power terminal. |
