Preliminary Operations; Earthing; Connecting The Loads, General Notes; Installing The Archimod® Battery - LEGRAND Archimod Operating And Maintenance Manual

6.2.2 Preliminary operations
Before connecting the UPS make sure that:
• input mains voltage and frequency correspond to the values on the UPS rating plate;
• earthing complies with the IEC standards (International Electronic Commission) or local regulations;
• the electrical system is equipped with all the necessary differential protections and thermal circuit breakers upstream
from the UPS input.

6.2.3 Earthing

It is mandatory to connect first the earth cable leading from the low voltage distribution panel to the EARTH terminal
before doing any other connections.
6.2.4 Connecting the loads, general notes
Before actually starting to connect the loads make sure the rated power of the UPS (OUTPUT POWER) indicated on its
rating plate is equivalent to or greater than the total sum of the load powers.
The type and cross section of the connecting cables must be chosen according to their operating current and laying must
be as established by existing laws.
A separate switchboard must be supplied for the load. It is a good idea to use disconnectors or circuit breakers conforming
to the IEC standards to protect the lines leading from the electrical panel.
Use adhesive labels or some similar way to indicate the following values on the system's general panel:
- maximum rated power of the total load;
- maximum rated power of the load at power intakes.
- if an ordinary switchboard is used (outlets for mains voltage and for the UPS), make certain that there is an indication
of the voltage applied on each outlet ("Mains" or "UPS") of the related power source.
6.2.5 Installing the Archimod® BATTERY
It is possible to connect external batteries to increase UPS autonomy of the 20, 40 and 60kVA models. The Archimod®
models 80, 100 and 120kVA always need external battery cabinets for working. For configurations with more than
one battery cabinet, all the Archimod® BATTERY units must be positioned on the same side as the Archimod® UPS and
connected in parallel with each other with minimum capacity cables as indicated in Table 7.
The type and cross section of the connecting cables must be chosen according to their operating current and laying must
be as established by existing laws.
In the TABLES chapter, Table 7 gives an example of the battery cable cross section to use as far as concerns using unipolar
cables, without sheath, in PVC and laid in a pipe above ground.
There are two different external battery cabinets for the Archimod® BATTERY units:
- a modular model consisting of a cabinet with an internal structure that uses battery boxes for up to a maximum of 12
series of N°3 12V 9Ah battery boxes, parallel to each other, (see chapter 3)
- a compact, non modular, economical model that uses a shelf architecture instead and on which the batteries are
placed. It can house 21 high capacity 12V batteries.
Note: Only battery cabinets of the same type can be connected together in parallel.
WARNING
The following instructions are of a prescriptive nature and it is imperative they be complied with.
Opening or removing the panels from the UPS Archimod® or Archimod® BATTERY you risk exposure to high and
dangerous voltages!
There are dangerous live parts inside the equipment due to the internal batteries even if all the fuse holder
disconnectors are opened. To remove the battery induced voltage, remove at least 1 battery box from each battery
shelf (to interrupt the battery string series).
