5. Operating.
5.1.
UPS commissioning and shutdown.
5.1.1. Preliminary controls.
•
Make sure that all connections have been done properly, and
respecting the labelling of the equipment and the instructions
of chapter 4.
•
Check that the power supply is correct.
•
Check that the UPS is Off (shutdown).
•
Make sure that all loads are shutdown «Off».
Loads can be connected after the UPS start up and
one by one. Before shutdown the UPS, check that all
loads are shutdown (Off).
•
Check that the thermal protection of the equipment is not
tripped.
•
It is very important to proceed in the established order.
•
For UPS views, see figures 1 to 6.
•
Turn “ON” the protection of the distribution panel.
5.1.2. Start up the UPS, with AC mains.
•
The UPS can’t supply voltage to the loads because the by-
pass mode is deactivated, code «0».
•
To start up the UPS, press over the key «ON» of front panel for
more than 1 second, the inverter will start up and at the same
time the status of the UPS will be displayed in the LCD of the
front panel.
The equipment is factory preset with the bypass mode
deactivated code «0» (there will not be output voltage
although there is voltage at the input of the UPS). To
change this factory setting go to section 6.2.6 and activate the
code «1».
•
Start up the load/s, do not overload the UPS.
5.1.3. Start up the UPS, with no AC mains
(Battery mode)
•
To start up the equipment with no AC mains -cold start-, it is
needed to press twice the key «ON» from front panel con-
secutively, keeping pressed the key in the second pulsation
for more than 1 second. The inverter will start up and at the
same time the status of the UPS will be displayed in the LCD
of the front panel.
In case of mains fault with the loads connected and turned
on, the time that the UPS will be working, will depend on the
battery charge level and the consumption of the own loads
connected to the output.
•
Start up the load/s, do not overload the UPS.
5.1.4. UPS shutdown with AC mains (on Inverter
mode).
•
To shutdown the inverter of UPS, press over the key «OFF» of
front panel for more than 1 second.
The UPS will shift to no output mode «0» -bypass deactivated-
(code «0») or bypass mode (code «1»), depending if the initial
configuration has been changed or not.
On bypass mode (code «1»), the UPS will still be supplying
output voltage through its bypass, so to shutdown the loads
completely, the circuit breaker switch from control panel will
have to be turned off too.
5.1.5. UPS shutdown with no AC mains (on
Battery mode).
•
Shutdown the UPS inverter by a simple pulsation of more than
1 second over the key «OFF». The UPS will be shutdown.
If the factory preset setting has been changed from
(code «0») to (code «1»), when mains voltage is re-
stored the equipment will still be supplying voltage to
the output through the bypass. It is needed to turn the circuit
breaker switch from control panel off, in order to leave the
loads with no voltage.
5.1.6. Battery test function.
•
To make a battery test with the equipment started up and mains
present, press over the button «ON» of the front panel for more
than 1 second, the test will start automatically.
•
It is possible to make the same battery test in the same condi-
tions, but with no AC mains. It is not recommended, because
depending on the status of the batteries and load level con-
nected at the output, there could be a break in the power
supply, which would mean a fault in the load power supply.
•
With this test, it is able to detect if the batteries are low, open or
not connected. It is possible to automate this test periodically by
setting the time to the required by the end-user.
5.1.7. Alarm silencer.
•
The acoustic alarm is activated when the equipment works on
battery mode. If it disturbs, it can be silenced by pressing for
more than 1 second the key «ON»/«MUTE».
The alarm will be automatically activated again due to low
battery (end of back up time). When it happens, loads and
UPS have to de shutdown, because the equipment will break
the output voltage in short.
•
If the alarm on bypass mode disturbs, press the key
«ON»/«MUTE» for more than 1 second to deactivate it. This
action will not affect to the warning and/or alarm fault.
5.1.8. EPO (Emergency Power Output).
•
Also it is know as RPO (Remote Power Output).
Check that the connector of Fig. A is inserted, before
proceeding with the start up.
When it is activated, the output of the equipment doesn’t
supply voltage and the screen of the LCD panel shows the
code «30». The EPO acronym are displayed in the screen of
the LCD panel instead of the output voltage figure.
It is a special situation, where it is done an immediate break
of the UPS output voltage and alarms, as a preventive or
emergency measures.
The EPO condition leaves the loads with no power supply,
but the UPS is not shutdown. To do it, the EPO condition has
to be released previously and then shutdown the equipment
through the key «OFF» (see table 4). To start up the UPS press
over the key «ON» (see table 4).
