4.4.6 Frequency Converter Mode Procedure

UK
NOTE: this functionality cannot be enabled / disabled using front panel buttons in units with front panel
based on LED indicators
When the unit is in frequency converter mode, it is possible to select with the LCD Display the output
frequency (50Hz or 60Hz) when the input frequency is in the 40-70Hz range. If the AC input is not within
tolerances, the output frequency is 50Hz or 60Hz (whichever is selected) in battery mode.
In order to activate the frequency converter mode, follow this procedure: with the unit operating in line
mode, press the inverter ON/OFF button to switch off the inverter and then disconnect the UPS from
AC mains input. Before the UPS shuts down, go to Menu 6 (Advanced options) and then to submenu
"Frequency Converter" and select ENTER FREQ. CONVERTER MODE. After that, go to submenu "Output
Frequency" and select 50Hz or 60Hz. When you re-start the UPS, it will start up in frequency converter with
the selected output frequency.
To deactivate this mode follow this procedure: press the inverter ON/OFF button and then go to Menu 6
(Advanced options) and then to submenu "Frequency Converter" and select EXIT FREQ. CONVERTER
MODE. Later, press the inverter ON/OFF button to re-start the unit and it will start up normally.
ATTENTION: when the unit is operating in this mode, there is a 50% power de-rating. This means that only
50% of the UPS nominal power can be used when operating in this mode.
For other details regarding Frequency Converter Mode, please see section 4.1.5.

4.4.7 UPS Shutdown Procedure

Press the inverter ON/OFF button. The inverter will be switched off but the UPS will supply power to the
connected loads via the internal bypass. To turn off all outputs and shutdown, it is necessary to disconnect
the UPS from AC mains power.
To restart UPS, see section 4.4.3.2 ("Normal Start-Up Procedure").

4.4.8 Remote Power Off (RPO) / Remote On Off (ROO)

The external connection to the RPO/ROO circuit is located on the rear side of the unit and is composed of
three connector pins, as shown in the next fi gures.
ROO RPO
The unit comes out of the factory with a wire which connects pins 1 and 2. For normal UPS operation, these
pins must be kept connected.
In order to use the Remote Power Off (RPO) functionality, please remove this wire and connect a normally
closed volt-free contact between pins 1 and 2. When this contact is open, the UPS will disconnect all loads
and shut down. To return to normal operation, disconnect the unit from AC mains power, close the contact
and re-start the unit following the procedure outlined in section 4.4.3.2.
In order to use the Remote On Off (ROO) functionality, please connect a wire between pins 1 and 2 (the
UPS comes out of the factory with that wire) and connect a normally closed volt-free contact between pins
2 and 3. When this contact is open, the UPS will disconnect all loads. After that, if the contact is closed the
unit will re-start and restore power to the connected loads.
For other details regarding ROO/RPO operation, please see section 4.1.6.
