Red LED

Green LED

Function

 

 

 

ON

OFF

A continuously incompatible operating condition

 

 

exists and an alarm has tripped. See “Protections

 

 

and Alarms” on page 3–7). The inverter is

 

 

automatically turned off until the fault/alarm has

 

 

been cleared.

OFF

ON

Regular operating conditions. Output is on and

 

 

delivering power.

OFF

fast flashing

Self-Diagnostic mode. Prior to enabling the

 

 

inverter the unit always performs a self-check and

 

 

diagnostics.

OFF

slow-short flash

Stand-by mode.

User Lines

The port with user lines is located at the rear panel of the rack mount frame (Figure 2-3). See Figure 2-7. The following table lists the signals:

Table 3-2User 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 3–5). If pin 2 is

 

 

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.
