6. OPERATION.
6.1. START-UP.
6.1.1. Considerations before start-up with
connected loads.
It is recommended to charge the batteries for at least
•
12 hours before using the UPS for the first time.
Although the device can operate correctly without charging
•
the batteries for the specified 12 hours, the risk of a prolonged
power cut during the first hours of operation and the available
backup time should be assessed.
Do not start up the device and loads completely until indicated
•
in Chapter 1.
When it is done, it should be carried out gradually to avoid
possible difficulties, at least during the first start-up.
If, in addition to the more sensitive loads, it is necessary to
•
connect high-consumption inductive loads, such as for laser
printers or CRT monitors, the starting up of these peripherals
will need to be taken into account to prevent the device from
crashing.
6.1.2. Initial start-up.
Make sure that all of the connections have been made
1.
correctly and with sufficient tightening torque, following the
instructions on the labelling of the device and in Chapter 5.
Check that the UPS and battery module or modules switches
2.
are 'Off'.
Make sure that all loads are "Off".
3.
Shut down the connected loads before starting the
4.
UPS and start the loads, one by one, only when the
UPS is running. Before shutting down the UPS, check that all of
the loads are 'Off'.
Check that there is a protective device against overcurrents
5.
and short circuits in the system upstream of the UPS.
The UPS will start up, the screen will light up, a beep will sound
6.
and the LEDs will start flashing. The UPS is in auto-Bypass
mode or Standby mode, which means it only consumes a small
amount of power.
The microcontroller that monitors the self-diagnostics is
powered; the batteries are charging; and everything is ready
for UPS activation. Battery operation is also in auto-Bypass
mode and in Standby mode as long as the timer is active.
Connect the unit to be powered to the terminal block on the
7.
rear panel of the UPS, using a cable that is no more than
10 metres.
USER MANUAL
Set the language, output voltage, password and date/time.
8.
Press the on/off button
9.
the front panel.
Check which operating mode is set on the screen and
10.
works normally without an alarm or fault. If necessary, refer
to Chapter "4.5. UPS operating modes." to configure the
required mode. For advanced UPS configurations, run the
monitor software that can be downloaded from the website
http://www.salicru.com.
6.1.2.1. UPS start-up with mains voltage.
Connect the input power cord, the UPS will enter Standby or
1.
Bypass mode.
Press and hold the on/off button for 1 second, the alarm will
2.
beep once.
The UPS will start up after the alarm is triggered.
3.
The UPS is running and operating in Normal mode.
4.
The start-up sequence can be seen in the following figure.
