6. Configuration and Start-up
WARNING
The instructions given in this chapter are not for an ordinary operator but for a specialized, authorised technici-
an. To be undertaken only if using the Personal Protective Gear specified in chapter 3.
As illustrated in the previous chapter the default configuration for the Tri Power X33 Mod HP UPS units entails a THREE-
PHASE INPUT and a THREE-PHASE OUTPUT.
If this type of connection is used, the equipment requires no additional configuration as it has already been set in the
factory.
If, however, the connection has been changed, then the following instructions
must
be referred to.
UPS Tri Power X33 Mod HP automatically recognises the voltage, frequency and number of phases in input even if the
electrical connection on the terminal block is changed. So once the input wiring to the terminal block has been modified
accordingly, no further configuration via the display is necessary.
ATTENTION
Please ensure the propper neutral connection before do the next steps.
The UPS Tri Power X33 Mod HP does not automatically recognise the electrical configuration on the output terminal
block. Therefore, it is ALWAYS necessary to select the load type applied via the display.
The default configuration for the UPS Tri Power X33 Mod HP units is THREE 120° phases, 400 VAC. For powers of 8 to 30
kVA the unit can be configured to obtain just one single-phase output (230 VAC).
If the unit is configured with a three-phase output, it is possible to select management of the three phases as follows:
SINGLE-PHASE outputs:
this setting is necessary if one single-phase lines were created at the UPS output. Please be
aware that in case of bypass operation the whole load connected to the input phase L1.
THREE single-phase outputs:
this setting is necessary if three separate single-phase lines were created at the UPS
output. In this case, the UPS manages the three outputs separately one from the other. For example, if an excessive
load is applied to one of the three output lines, the bypass will intervene only on the overloaded line while power is
guaranteed on the other two by the UPS.
THREE 120° phases
: this is the default setting and it is normally used if three-phase loads have been applied in out-
put from the UPS (e.g. three-phase electrical motors) or if three-phase and single-phase loads are being powered by
the UPS. In this case the UPS manages the three output phases, protecting the three-phase load. For example, if an
excessive load is applied to one of the three output lines, the automatic bypass switches all three output lines.
To select the system output configuration correctly on the display follow the instructions given in paragraph 6.4.
Check the following before powering the equipment:
1.
Make sure the input switch S3 for powering the UPS in the distribution box is open;
2.
Ensure that the fuse carrier isolating switches of the UPS batteries (F B+ and F B-) and those of the Tri Power X33
Mod HP BATTERY (if used) are open;
3.
Check that the maintenance by-pass switch S1 and the UPS output switch S2 are both in the OFF position.
4.
Ensure that the input and output wiring is correct;
5.
check correct cycling of the phases in input;
6.
Check that the mains input parameters (power voltage and frequency) are compatible with those specified on
the UPS data plate.
6.3
Checks prior to switch on
INDICATION
Ensure that the link at the back of the UPS on connector H between Pin 3 and 4 is present (see chapter 5.2.4). If this link
is not present the UPS is not able to start up and the message „E.P.O active“ is displayed and in advance the UPS is shut-
down itself.
