3.3.7 Connecting interface devices
The UPS is equipped with two interface ports: a DB9 communication port and an SNMP card slot
(see section 3.3.8). Prepare the included serial communication cable (for DB9 communication port
connection) or the network cable (for SNMP communication connection) as follows:
1. Choose from the 2 provided ferrite beads the smaller
one for serial communication and the bigger one for
SNMP communication.
2. Place the cable part that is close to the UPS connector
inside the ferrite bead. For SNMP communication twist it
once around the ferrite and place the second winding
also inside the ferrite bead (fig 3.3.7.a / 3.3.7.b).
3. Close the ferrite bead such that the cable remains
inside it (fig. 3.3.7.a / 3.3.7.b).
You can now connect the DB9 port to a computer by connecting the previously prepared serial cable
(fig. 3.3.7.c / 3.3.7.d). Additional signals can be read from the serial connector. See section 5.1 for more
information.
Open the SNMP slot by removing the two screws and the cover, then pull in the easy installation SNMP
Card and connect previously prepared network cable (fig. 3.3.7.e / 3.3.7.f). See section 5.2 for more

3.4 PARALLEL OPERATION (ONLY FOR 8/10 KVA)
The paralleling cable delivered with each UPS allows you to connect up to 3 UPS together in a parallel
system.
3.4.1 Installation of a parallel system
1. All inputs of the UPS must be supplied from the same phase. Be sure that L1 / L2 / N correspond on all
the units of the parallel system. All inputs have to be protected individually by fuses. The values of
these fuses should correspond to the values mentioned in section 3.2.
2. All outputs must be connected together, supplying the load. It is advised to install switches (S 1, 2, 3
fig 3.4.1) in the output wiring, in order to be able to isolate a unit from the remaining system for
service and maintenance purposes.
3. Use insulated copper input and output wiring, rated 90°C (194°F) wire size based on the ampere
capacities given in Tables 310-16 of the National Electrical code, ANSI/NFPA 70-2008.
4. The length of all input cables from the input junction (Li, fig. 3.4.1) to the UPS inputs should be equal.
The same applies to the cables from the outputs to the output junction (Lo, fig. 3.4.1). The minimum
length of the input as well as the output cables is 3 meters.
5. The overall system load may not exceed 100% load of a single UPS in the configuration without the
addition of an external maintenance bypass.
NOTE
The units connected in parallel must be the same power rating (i.e. 8 kVA-8 kVA not
8 kVA-10 kVA) and must have the same output voltage setting (i.e. 120V-120V not 120V127V). Before starting up a parallel system be sure that the output terminals on all UPS
are connected in the same way (see section 3.3.9, fig. 3.3.9.d).

3.4.2 Installing the parallel connection
NOTE
Ensure that the UPS is isolated prior to installation; no live input source may be
connected to the UPS during the installation procedure. Open all the input/output
switches/breakers on the power distribution and ensure no one is able to close
them during this installation step.
1. Localize the parallel port on the rear side
of the unit (fig. 3.4.2.a)
2. Connect the DB 15 parallel cable provided
with the UPS to the parallel port (fig.
3.4.2.b) and tighten it.
3. One cable connects two UPS in parallel.
To connect a third UPS into the parallel
system, repeat the process as above
(fig. 3.4.2.d)
4. For a quick start of the system proceed
with section 4.2.3
5. Each UPS needs a different configuration
of the DIPswitch as identification of unit
in the parallel system (fig. 3.4.2.c).

4.4.1 On bypass
The UPS is equipped with an automatic bypass switch. This switch automatically transfers the load to the
main power supply if the UPS is unable to deliver the demanded output power due to overload or over
temperature. If all 5 load LED are illuminated, bypass operation is caused by an overload. If only first
runtime LED is illuminated, bypass operation is caused by over temperature (see 4.4.8 tab .1).
The UPS will switch back to normal operation when the overload has been removed. When temperature
drops below alarm level unit can be switched back to normal operation. If a power failure occurs during
bypass operation, the UPS will switch to battery if possible, otherwise output power is lost.
4.4.2 On battery
In normal operation conditions, if a main power supply failure occurs, the UPS uses the energy stored in
the batteries to supply the load. The runtime capacity LED bar will show the remaining time (see 4.1). For
further information about runtime refer to chapter 9, Battery runtime. The UPS will shutdown:
• After the batteries have been discharged (automatic restart if enabled), or
• If keypad ‘UPS off’ is pressed (restart via front panel required), or
• If a ‘UPS shutdown’ command is given by the computer (via UPS monitoring software). Restart
depends on the setting of “auto-restart” function (see 4.4.12).
4.4.3 Battery low (end of runtime)
If during battery operation the buzzer starts beeping every 5 seconds and the first LED of the battery
runtime bar starts blinking the batteries are nearly discharged: the remaining runtime is less than 2
minutes (default setting, adjustable via the UPS monitoring software). Controlled shutdown of any
computer equipment is absolutely necessary when this alarm is raised.
If the UPS operates at 100% load, the shutdown procedure should be completed within 2 minutes after the
‘battery low’ alarm started. If only part of the output capacity of the UPS is used this period can be longer,
with aged batteries this period can be shorter. When the batteries are fully discharged, the UPS is no
longer able to supply the connected equipment and eventually output power is lost.
4.4.4 Bypass out of limits
The mains voltage or mains frequency is outside bypass tolerance but inside UPS input tolerance (see
chapter 9). Bypass operation is inhibited: if for whatever reason the UPS is not able to deliver the required
output, output power is lost. If the input frequency is often out of tolerance – during which bypass
operation is inhibited and an alarm is generated – it may be useful to disable bypass function (via UPS
monitoring software) after which the unit operates as a UPS without automatic bypass switch.
NOTE
The unit can be used as frequency converter: the input frequency range is
40-70 Hz; the output frequency is selectable 50/60 Hz, via UPS monitoring
software. If the unit is used in this configuration, the bypass function is no
longer available.
4.4.5 Overload
The demanded power exceeds the nominal capacity of the UPS. The “overload warning” alarm occurs
when the load exceeds 150% the UPS will immediately switch to bypass, assuming that the conditions for
a transfer to bypass are fulfilled.
If an overload condition between 110-150% persists, the UPS will also switch to bypass operation. In both
conditions the “overload” alarm (see 4.4.8 tab. 1) is generated. During an overload the UPS may
automatically switch off within a few minutes (load dependent) and output power is lost:
• if a transfer to bypass is inhibited (see section 4.4.4), or
• if the bypass function has been disabled (see section 4.4.4), or
• if the UPS operates on battery (see section 4.4.2).
To avoid these problems, be absolutely certain that the power demand of the protected equipment is
within the limits of the UPS.

4.4.6 Replace battery
Either the batteries are almost chemically worn out or the battery wiring, including the battery fuse, is
faulty. If the batteries are aged, they must be replaced as soon as possible to ensure full protection for
your equipment (see section 7.4.1 & 7.4.2). Perhaps the 'replace battery' alarm occurs after a test, which
was started immediately after installation or after a power failure. In this case the alarm may be incorrect,
as the batteries have been (partly) discharged during transport or storage or during the power failure. For
this reason we advise to execute battery test only after 5 hours on line operation with no mains
failures. This allows the UPS to recharge the batteries.
4.4.7 Alarm priority
‘General alarm’ comprises a group of alarms; the buzzer behavior indicates the priority of the generated
alarm.
ON: Battery not connected (see section 4.5)
1 / 0.5 sec.: Overload (see section 4.4.5)
1 / 4 sec.: General Alarm
1 / 60 sec.: Battery test failed (see section 4.5)
1 / 120 sec.: On bypass (see section 4.4.1)
4.4.8 Fault mode
The UPS may be in “fault mode” if the following failure occurred:

In “fault mode”, the UPS is “forced” on bypass or stand-by. After having solved the cause of the fault
condition you have to press the ‘UPS off’ button for 0.5 seconds to switch the UPS to normal mode or
restart the unit.
4.4.9 Stand-by
In stand-by mode the UPS is turned off (output power is lost) and the batteries are being recharged.
To put the unit in this condition press for 1 second the ‘UPS off’ switch, the unit switches to bypass.
Press one more time ‘UPS off’ switch for 1 second. The unit is now in stand-by mode. Most changes of
UPS settings are only possible in bypass or stand-by mode.

4.4.10 Remote Emergency Power Off (REPO)
REPO may be created using either normally open or normally closed switch. The unit is shipped with a
jumper connected between pin 3 and 4 (fig.4.4.10.a), corresponding to no REPO functionality.
In case of connection with a normally open contact, this jumper must be removed and a normally open
switch cabling has to be connected between pin 1-2 (fig. 4.4.10).
In case of connection with a normally closed contact, the jumper must be shifted between pin 1 and 2,
and the normally close switch has to be connected between pin 3 and 4 (fig. 4.4.10).
5/6 kVA 8/10 kVA
fig.4.4.10
When REPO is activated the UPS will transfer to stand-by mode (see 4.4.9) and output power is lost. It’s not
possible to restart the unit while the REPO is activated, thus, depending on the used switch, the
connection must be restored by closing or opening the contact. Press “UPS off” button 2 times within 4
seconds to be able to restart the unit.
4.4.11 No load shutdown
If no load shutdown is enabled, the load is less than 5% and in case of utility failure the UPS will switch
off avoiding deep discharge of the batteries and output power is lost. “No load shutdown” is disabled as
default. It’s possible to enable it via UPS Monitoring Software.
4.4.12 Auto Restart
Default enabled “Auto restart” may be disabled via UPS monitoring software. Auto Restart acts after the
UPS has been shut down during a mains failure:
- if the function is set “enabled”, the UPS will automatically restart when the mains returns
- if the function is set “disabled”, a manual restart is required, either as explained in section 4.2.1 / 4.2.2
or via the UPS monitoring software.

properly connected.
If the test detects a battery disconnection, the corresponding alarm will be generated (see section 4.4.7).
• Quick battery test
A quick battery test may be launched to check whether batteries are healthy. To start the test,
press ‘UPS on’ button (see section 4.1) for 0.5 seconds when the unit is in “normal operation”
conditions (see section 4.3.1).
In case of failure the corresponding alarm will be generated (see section 4.4.6 / 4.4.7)
• Deep battery test
A deep battery test will update the runtime calculation and may be started via the UPS monitoring
software. The test will start only if the battery charge level is higher than 90% and the load must be
at least 20% of the nominal rating. The runtime calculation will be updated only if the test can run
uninterrupted till complete battery discharge.
NOTE
When executing a deep battery test the available runtime in case of mains
failure may be shorter than normal. Don’t execute this test if reduced battery
runtime is not acceptable.
NOTE
It’s possible to reset the battery test, by pressing the ‘UPS off’ switch (see 4.1)
for 1 sec. The UPS will switch to bypass mode.

6.2 EXTENDED RUNTIME
Extended runtime can be obtained by connecting a separate battery extension pack to the UPS. In this
case the UPS must be informed about the new total battery capacity to allow a reliable recalculation of
the available runtime (via UPS monitoring software). Depending of the charge condition of the new
batteries the new runtime calculations may temporarily be unreliable.
Additional batteries increase the recharging time for the unit; all other operational information is the same
as for standard models. The following table shows runtimes with up to 3 Battery Packs. 1 Battery Pack is
the normal configuration.

Page 36
7.4 BATTERIES
The service life of the battery is from 3 to 5 years, depending on the operating temperature and on the
number of discharge cycles.
As a healthy battery is critical to the performance of the UPS, an automatic quick battery test is performed
regularly to ensure failsafe operation (see section 4.5). When the condition of the battery is critical, a
'replace battery' alarm will be activated (see 4.4 and 4.4.6). Replace the batteries as soon as possible.
General guidelines:
• When replacing the batteries, use all of them of only the
same type and size.
• Never short the battery terminals. Shorting may cause the
battery to burn. When working with batteries remove
watches, rings or other metal objects and only use
insulated tools.
• Avoid charging in a sealed container.
• Proper disposal of batteries is required: refer to your local
codes for disposal requirements.
• Never dispose batteries in fire: they may explode.
• Never disassemble or reassemble batteries; their contents
(electrolyte) may be extremely toxic. If exposed to
electrolyte, wash immediately with plenty of water, if eye
contact occurs flush with water and contact a physician.
Don’t throw batteries away,
treat them as harmful
waste
