3.5 Initial startup
CAUTION
SWITCH OFF THE CONNECTED LOADS BEFORE
TURNING ON THE UPS. SWITCH ON THE LOADS
ONE BY ONE AFTER THE UPS IS TURNED ON.
SWITCH OFF ALL OF THE CONNECTED LOADS
BEFORE TURNING OFF THE UPS.
To start up the UPS:
1. Verify that the total equipment rating does not exceed the
UPS capacity.
2. Check that all cables are connected correctly and well-
fixed mechanically.
3. Set the upstream circuit breaker (not included) to the
“power-on” position (ON). The UPS LCD panel will
illuminate and show a welcome screen.
4. The UPS transfers to bypass-mode.
5. Keep the power-on button
on the UPS LCD panel
pressed for at least three seconds.
6. Check the UPS display for active alarms or notices.
Solve any active alarms. For more information, see
“Troubleshooting” in Chapter 6.
7. Verify that the UPS is operating normally and that the
loads are powered.
8. Adjust the date and time settings. For more information,
see Chapter 4.4.2.5
NOTE
AT THE INITIAL STARTUP, THE UPS SETS THE
SYSTEM FREQUENCY ACCORDING TO THE
FREQUENCY IN THE INPUT LINE (INPUT
FREQUENCY AUTO-SENSING IS ENABLED BY
DEFAULT). AFTER INITIAL STARTUP, AUTO-
SENSING IS DISABLED UNTIL MANUALLY
RE-ENABLED THROUGH THE OUTPUT
FREQUENCY SETTINGS.
NOTE
AT INITIAL STARTUP, THE INPUT VOLTAGE AUTO-
SENSING IS DISABLED BY DEFAULT. AFTER
MANUALLY ENABLED IN THE VOLTAGE
SETTINGS, THE UPS OUTPUT VOLTAGE WILL BE
SET ACCORDINGLY TO THE INPUT VOLTAGE.
AFTER A SUBSEQUENT STARTUP, AUTO-
SENSING WILL BE DISABLED UNTIL MANUALLY
RE-ENABLED IN THE OUTPUT VOLTAGE
SETTINGS.
9. If you connect the REPO port, test this function by
activating the external REPO switch and verifying that its
status changes on the UPS display.
3.6 Emergency power off (EPO)
The EPO connector can be used to block the output of the
UPS in case of an emergency. The EPO connector can be
configured as Normally closed (NC) or Normally opened (NO)
through the USB or RS232 port.
By default, the EPO connector is Normally closed (NC) by a
jumper in the rear panel. If the jumper is removed, the UPS
output will not supply energy to the load until the EPO status
is changed.
Enable the EPO status
Disable the EPO status
Figure 26: EPO connector
To return to normal status, the EPO connector must be
closed. Enter the LCD menu to clear the EPO status (for more
information, see Chapter 4.4.2.3). The UPS alarm is cleared
and bypass mode is recovered. Set the UPS to inverter mode
manually.
