Note:
The installing method of bypass module is the same as the
power module.
6.3. BATTERY
The battery set can be based between 36 and 44 blocks con-
nected in serial, but it will always be an even number due to
the internal structure of the equipment, which needs a mid tap
or central point (neutral) of them. At the same time, the back up
time together with the required power to feed the loads esta-
blishes the needed capacity of the battery in Ah.
In Fig. 22, “N” means the total quantity of battery blocks con-
nected in serial, being able to select it among the figures above
stated.

Danger:
The battery terminal voltage is of more than 400Vdc, please
follow the safety instructions to avoid electric shock hazard.
Ensure the positive, negative, neutral electrode is correctly con-
nected from the battery unit terminals to the breaker and from
the breaker to the UPS system.
6.4. CABLE ENTRY
Cables can enter the UPS cabinet from the top. Cable entry is
made possible through a blanking plate fitted at the top of the
equipment. The cable entry is shown in Fig.23.

6.5.1. Specifications
The «Recommended installation» information for each input
and output setting is available with the supplied
documentation, manual and/or CD. In that information is shown the
circuit diagram, as well as the protection size and minimum cross
section of the wires that are connected to the equipment, taking into
account the nominal operating voltage. All figures are calculated for
a
maximum total cable length of 30 m
between the distribution
panel board, equipment and loads.
•
For longer lengths correct the cross sections accordingly,
in order to avoid dropping voltages, by respecting the
Regulations or norms corresponding to the country.
•
In the own documentation and for each setting, it is
available the information for «N» units in parallel, as well
as the features of the own «Backfeed protection».
Attention:
The CB with RCD (Residual Current Device) is not su-
ggested for the system.
