4.5 OTHER FEATURES
4.5.1 ECO-mode
The UPS is equipped with the “ECO-Mode” feature.
If the feature is enabled, the load is operated on mains through the electronic bypass switch.
If the mains is interrupted or out of limits the load is automatically transferred to the inverter.
Operating the load on mains improves the efficiency of the UPS with 5-8% and saves on
energy cost.
As the unit produces less heat in ECO-mode also the energy cost of an airco installation will be
reduced.
We advise not to use the ECO-mode in case of an unstable mains and critical load but only in
case of a good mains supply combinet with a less critical load (e.g. lighting).
After enabling the ECO-mode (please refer to service screens 4.3.3) the standard menu
change to:
LP 15-31
load 37%% ECO
4.5.2 Shutdown
“Remote shutdown“:
Using communication capabilities, the computer can direct the UPS to turn itself OFF following
controlled shutdown of the system.
Subsequently the UPS will remain OFF for at least a few seconds (see also 4.3).
LED “operation” will blink green.
The unit will start up again as soon as the mains returns.
“No-load shutdown”
The UPS will also switch OFF if the load is < 2% of the maximum load, and the input is absent
for more than 10 minutes.
For more information see chapter 4.3.2, message “SHUTDOWN ALARM”.
“Emergency shutdown” (EPO – Emergency Power Off)
Por more information see chapter 4.3.2, message “IMMEDIATE SHUTDOWN”.
4.5.3 Mains start
The UPS is able to start, even if the batteries are not connected.
