Tabla 2. Screw metric of the equipment terminals, maximum ø of
the terminal to fit in and tightening torque.
• The information regarding the terminals of the equipment of
each configuration and power rate is detailed in table 2 (screw
metric, tightening torque, maximum diameter of the wire per-
missible by the terminals).
• In parallel systems, the length and cross section of the wires
that goes from the panel board to the each UPS and vice
versa, will have the same for all of them, without any exception.
• Always take into account the cross cable section, as regards to
the size of the own terminals of the switches, in order to em-
brace all their section properly for an optimal contact between
both elements.
• In the nameplate of the equipment, nominal currents are only printed
as it states the EN-IEC 62040-1 safety standard. The input current
calculation, has been done taking into account the power factor and
the own efficiency of the equipment.
• If other peripheral elements are added to the UPS or parallel system
input, output or bypass like transformers or autotransformers, take
into account the currents stated in the own nameplates of those
elements in order to use the suitable cross sections, always re-
specting the Local and/or National Low Voltage Electrotechnical
Regulations.
• When a UPS or parallel system include a galvanic isolation trans-
former, as standard, option or installed by yourself, either at the input
line, bypass line, output or in all of them, protections against indirect
contact (RCD) have to be fitted in at the output of each transformer,
because in case of electrical shock in the secondary winding (output
of the isolation transformer), its isolating feature will block the trip-
ping of the protections located in the primary winding.
• As a reminder, all isolation transformer installed or supplied from
factory, has the output neutral connected to earth by means of a
bridge that connects the neutral and earth terminals. In case, an

isolated neutral were required, remove this bridge, by taking the
precautionary measures stated in the respective local and/or na-
tional low voltage regulations.
• To enter the cables inside the cabinet, there are either cable glands
(PR) assembled in the metallic structure or an only one opening as
a register mode.
• Models with power rate higher than 40 kVA (LV) / 80 kVA (HV),
have a rod to fix the connection wires of the equipment to it, by
means of clamps (BF).
Once the cables are connected to their respective terminals, pro-
ceed to fix them by means of clamps to the rod (BF).
• In case of installing the equipment in IT neutral regime, the
switches and circuit breaker protections must break the NEU-
TRAL as well as the three phases .
5.1.4.5. Preliminary considerations before connecting, as
regards to batteries and protections.
• Inside the battery cabinet there are accessible parts with HAZ-
ARDOUS VOLTAGES, so electrical shock risk exists, therefore it
is classified as RESTRICTED ACCESS AREA. This is why the key
of the battery cabinet will not be available to the OPERATOR or
END USER, unless he has been trained properly.
• At least, battery protection is always done by fuses and their
physical layout depends on the battery location. Next, the dif-
ferent groups are described:
a. Models up to 20 kVA (LV) / 40 kVA (HV) with «standard» back
up time. Batteries are supplied fitted in the same equipment
cabinet. Also, for each one of the power rates, the standard
back up time in the «0/» and «/» versions, leaves the needed
space for the batteries in the same cabinet of the equipment.
