Once the UPS is connected, replace the cover (TB) and close the door (PF) with the lock (CL).
The cable cross section of the bypass, input and output lines shall be determined from the maximum
currents for the first two and from nominal ones for the output, by respecting the local and/or country Low
Voltage Electro-technical standards.
To calculate the cross cable sections, take the figures of the current given in tables 1 or depending on the
model, single or three phase configuration and nominal voltage value of the UPS.
The equipment nameplate only gives the nominal currents as stated in safety standard EN-IEC 62040-1.
The protections in the distribution board will have the following characteristics:
For the input and bypass lines, type B earth leakage breakers and curve C circuit breakers.
For the output (supply loads), curve C circuit breaker.
If input, output or bypass peripherals such as transformers or autotransformers are added to the UPS,
currents stated on the nameplates of those components have to be taken into account, in order to use the
suitable cross sections, by complying with the Local and/or National Low Voltage Electro-technical
Regulations.
When a piece of equipment has a galvanic isolation transformer, as standard, as an option or installed by
the end user, at the UPS input, bypass, output line or in all locations, they have to be fitted with protections
against indirect contacts (earth leakage breaker) at the output of each transformer, because its own
isolation feature will impede the tripping of protections installed at the primary winding of the transformer
in case there is an electric shock in the secondary winding (isolation transformer output).
May we remind you that all isolation transformers supplied or installed from factory have the neutral cable
connected to the ground through a cable bridge between the neutral and ground terminals. If you require
an isolated output neutral, please remove this bridge, taking the stated precautions to comply with local
and/or national low voltage standards.
The supplied cable passages fitted to the metal structure are those recommended to correctly attach the
input, output and bypass wires with the sections determined by the National Low Voltage Electro-technical
Regulation in accordance with the currents of the device.
If these sections have to be changed for any reason, it should be done from a separate distribution box and the
sections indicated should be maintained from the device to the distribution box.
In standard equipment up to 40 kVA, batteries are supplied inside the UPS enclosure and for higher power
rates; they are supplied in a separate cabinet. By default, the UPS has a battery fuse-holder switch (Q3)
with 3 fuses for models up to 40 kVA or battery switch (Q3) for models with higher power rate. The battery
cabinet has a fuse holder switch (Q8) with 3 fuses, for both models with a higher power rate of 40 kVA and
for extended back up times. In any case, fuses are supplied together with the documentation. Open fuse
holder switch (Q3) or (Q8), install the 3 fuses and
WAIT until it is indicated before CLOSING IT
.
IMPORTANT FOR YOUR SAFETY
: Do not turn the battery fuse holder switch (Q3) or (Q8) located in the
battery cabinet to “On” (Close), until the equipment is switched on completely because it may cause
irreversible damage to the equipment or accidents.
