WARNING
The instructions given in this chapter are not for an ordinary operator but for a specialized, authorised technician
only if he is using the Individual Protective Gear specified in chapter 4.
As illustrated in the previous chapter the default configuration for the Archimod® 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, on the other hand, the output terminal block configuration is altered during installation (only Archimod® 20 and 40kVA,
see chapter 6) the inverter’s configuration must also be changed via the display before starting the UPS, referring to the
following instructions.
2.1 Input configuration
UPS Archimod® 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 and
accordingly, no further configuration via the display is necessary.
ATTENTION
Ensure that the neutral is always connected.
2.2 Output configuration
The UPS Archimod® does not automatically recognise the electrical configuration on the output terminal block. It is
therefore ALWAYS necessary to select the electrical configuration on the output terminal block via the display when
installing, depending on the load type applied.
The output default configuration for the UPS Archimod® units is THREE 120° phases, 400 VAC.
For power 20 kVA and 40 kVA the unit can be configured to obtain just one single-phase output (230 VAC).
Follow the instructions in paragraph 2.4 to ensure you select, via the display, the correct output configuration for the
system.
If the unit is configured with a three-phase output, it is possible to select management of the three phases as follows:
• THREE 120° phases: this is the default setting and it is normally used if three-phase loads have been applied in output
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.
• 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.
2.3 Checks prior to switching on
Check the following before powering the equipment:
1. Make sure the carrier isolating switches for powering the UPS in the distribution box are open;
2. Ensure that the fuse carrier isolating switches of the UPS batteries (F B+ and F B-) and those of the Archimod® BATTERY
(if used) are open;
3. Check that the maintenance bypass switch and the UPS output switch are both open, in the 0 position.
4. Ensure that the input and output wiring is correct;
5. Check correct cycling of the phases in input;
6. Check correct cyclicity of the phases in mains input and in bypass input (if used).
7. Check that all power modules are properly plugged and that all the securing screws for the power modules are
screwed right down into their slots; use only and exclusively M4x20mm Allen screws and do not tighten them with
too much force.
