Pay attention to proper polarity if one is using a semiconductor switch type. A relay or
other mechanical control is a preferred method.
Emergency Power Off (EPO)
This input is used to shut down the UPS from a distance. This feature can be used for
emergency power down. There are two modes of operation, normally closed at X52 and
normally open at X12. Remote shut down terminal X52 pins 1 and 2 are as factory default
linked (X12 is open). When the loop on X52 is opened, the logic circuitry will immediately
shut down the UPS output.
Note!
EPO does not necessarily disconnect supply to load when unit is on internal or external
bypass. Quaranteed disconnection of bypass supply has to be through a separate
disconnect switch located in the supplying switchgear cabinet.
In order to have the UPS running again pins 1 and 2 of connector X52 have to be reconnected
and the UPS started manually. The pins must be shorted in order to keep the UPS running.
Maximum resistance is 10 ohm. The EPO shall not be galvanically connected to any mains
connected circuits. Reinforced insulation to the mains is required.
If the use of normally open EPO operation is desired, the loop on X52 has to be retained and
the normally open EPO switch connected to X12. Operation is as above.

Select Maximum charging current from User Settings menu. Default setting is 3.0 Amps and it
is changeable up to 20 Amps. Minimum step is 0.1 A.
Note!
Maximum charging current is dependent on output load and power rate of the UPS. If the
UPS is supporting maximum output load the highest level of Maximum charging current is
3.0 A, which is also the default setting. As a thumb rule, 1 kW decrease in the load provides
extra 2.0 A charging capacity. For example, the charging capacity is 5 Amps at 8 kW load,
and 7 A at 7 kW load.
Using relay outputs
Relay outputs can be used for remote alarm indications.
Each relay has four standard pre-programmed settings for alarms:
• on bypass, UPS ok, battery low, on battery
One of the standard relay settings is “custom” that can be customised by the user.
The procedure to select customised alarms:
1. Push any key of the control panel to enable the functions on the LCD screen.
2. First select “SETTINGS”, then “USER SETTINGS” and finally “RELAY CONFIG” from
the LCD menu.
3. Select the relay what is needed to be configured (ALARM-1 is fixed relay output X57).
4. Select “empty” to clear old settings.
5. Select “custom” and activate needed alarms with the button on the right.
6. After the selection press “OK” button
