Four front-panel LED’s show inverter status

"POWER" (green)

- The "POWER" LED is lighted on as soon as the unit starts
supplying power to the load

- It indicates normal operation.

"O.T." (red)

- When lighted on it indicates that the internal temperature is
approaching the thermal shutdown thre

shold. In addition to

the visual indication, the unit sounds audibly.

"O.T." and "FAULT" (red)

- The thermal shutdown threshold has been exceeded.

Note: The thresholds are factory set and not changeable
(see "Factory Settings" on "Appendix B").

"FAN FAIL" (red)

- The "FAN FAIL" LED is lighted on when the speed of one of
the fan falls below its nominal value.

"FAULT" and "FAN FAIL"

- They are lighted up at the same time if more than one fan
has stopped or a general malfunction is detected. The unit
continues to works until an OT is detected.

"FAULT" (red)

- "FAULT" LED is lighted on when a general failure happens.
(for general fault conditions see table below)

The STAND BY status shows the DC source is connected; loads are disconnected by two internal relays.
As soon as the DC input voltage is applied, "STANDBY…" is displayed.
Three operations are possible (see Fig.1):
(a) Press <ESC> to enter into the SETTINGS menu's first page, or
(b) Press <ENTER> to visualize the configuration mode of the unit. Two screens are presented

automatically within a few seconds. The first (1) shows the mode of the unit (Stand Alone or Parallel
mode). In case of Parallel mode the screen tells whether the unit is master or slave. In case of Stand
Alone mode the units is always a master The second screen (2) shows if the unit has the optional Static
Transfer Switch.
Pressing the "ESC" key shows the SETTINGS menu’s first page, or

(c) Press <ON/OFF> to power up the unit. The display shows "STARTING…" and the screen (3) appeares

automatically after a few seconds. Using <UP> / <DOWN> keys it is possible to scroll six screens on the

3 Operating modes

The unit has two operating modes:

- Stand Alone mode: there is only one inverter in the system

- Parallel mode: there are several inverters working in parallel (max. number of parallelable units: 8)

The default mode is Stand-Alone.
Trained personnel should set the operating mode before the system starts supplying the load (see SERVICE

menu on "Appendix A").
It is possible but not recommended to change the operating mode while the inverter is operating.

ATTENTION:

incorrect unit setting may lead the system to latch up

Notes

When the unit work in Parallel mode it is not possible to change the following parameters in the

•

SETTINGS menu: Vout, Iout, Frequency. The access to these parameters is locked to avoid system
conflicts (see also Notes on page 8).

4 Controller status

When operating in Parallel mode the controller inside each unit can operate in two modes:

- Master: provides the commands for the whole system of paralleled inverters. There is only one master.

- Slave: it follows the commands of the Master

When working in Stand Alone mode the status of the unit is Master.
Controller statuses are assigned automatically and cannot be changed by the user. In case of failure of the

master in a parallel configuration a new master is selected automatically and control of the system of
paralleled inverters is transferred automatically to the new master.

If the user wants to make changes when operating in Parallel mode, he unit must first of all set to Stand­Alone mode using the following procedure (to be repeated for each unit working in parallel):

1. Set the unit to Stand-alone mode:

• on the SETTINGS menu select the SERVICE submenu. Press <Enter> to confirm the choice.

• Insert the 2nd level password (default password is “1111”; use the <UP> and <DOWN> keys to select

the digits. Press <Enter> to confirm.

• Select the OPERATING MODE submenu and press <Enter>.

• Change "Mode = 2"(parallel mode) into "Mode =0"(stand-al

one mode). Use the <UP> key to insert the

character "0".

2. Change the Vout, I
