Use of the supplied metal plates (item 6 in ) to join the different
EBMs to the UPS in case of installation in tower format, as shown
below:
Fig. 22. Connecting the different modules.
Before starting the connection process between the bat-
tery module or modules and the unit, check that the unit
and the loads are in the "Off" position.
Likewise, when the batteries are installed by the user on their own,
the protection fuse or disconnect switch must be deactivated.
The battery module is connected to the unit via a hose equipped
with polarised connectors at both ends, which is supplied with the
former. For this, the unit and the battery module have two separate
connectors that allow them to be connected.
The battery modules also have two connectors that allow the
modules to be linked in parallel.
NOTE: The connection cables cannot be extended by
the user.
Each battery module is independent for each unit.

IMPORTANT FOR SAFETY: If the batteries are installed
independently, the capacitor group must be equipped with
a bipolar automatic switch or disconnector fuse with the rating
indicated in the following table:

5.3.3. Connection to IEC connectors or output
terminals.
SLC TWIN RT3 devices feature female IEC output connectors.
Models up to 2 kVA: 2 groups of 4 x 10 A IEC connectors
•
identified as "Output connectors" and "Output programmable
connectors", configurable through the control panel and/or
WinPower.
3 kVA models: same connectors as models up to 2 kVA and an
•
additional 16A IEC connector.
Do not connect loads that in their entirety exceed the spec-
ifications of the device, as this would cause inconvenient
cuts in the power supply of the loads connected to the output.
If, in addition to the more sensitive 'critical loads', it is necessary
to connect high-consumption inductive loads, such as for laser
printers or CRT monitors, the starting up of these peripherals will
need to be taken into account to prevent the device from crashing.
We do not recommend connecting loads of this type due to the
amount of power they absorb from the UPS.
5.3.3.1. Connection of loads.
Connect the loads to the 10 A IEC connectors.
It is important to consider the two groups of IEC connectors
available, those for "Critical Loads" (Programmable Output
Connectors) and those for "Non-Critical Loads" (Output Connectors).
By definition, "Critical Loads" are understood to be those that,
when they stop working or when they work inappropriately,
can cause economic damages.
The IEC connectors indicated in to as "Programmable Output Con-
nectors" can be programmed via the control panel as critical. In this
case, the autonomy of the batteries will be reserved for the loads
connected to the aforementioned IEC connectors. Take into account
that by default they are established as "Critical Loads".
