4.4. CONNECTION Of ThE INPUT, OUTPUT AND
PROTECTIVE EARTh WIRING.
4.4.1. Notes for the installation.
The UPS has to be installed in a well cooled place, far from 1.
water, inflammable gases and corrosive agents.
Make sure that the front and rear cooling wholes of the UPS 2.
are not blocked. Leave 0,5 metres of space around the UPS as
minimum.
Drops of water condensation can appear if the UPS is un- 3.
packed in a low temperature environment. In this case it is
necessary to wait until the total unit is dry before proceeding
to the installation and the starting up. Otherwise electrocution
danger will exist.
4.4.2. Installation.
The installation and wiring must be done according to the local
codes and following the instructions of professional staff.
Due to safety, turn off the power supply before proceeding to the
installation. The battery circuit breaker also needs to be turned off if
it is a model with extended autonomy (version B1).
Open the terminal cover located in the rear side of the UPS. 1.
See diagram according to the model.
For the model SLC-4000-TWIN (B1) / SLC-5000-TWIN (B1) / 2.
SLC-6000-TWIN (B1) / SLC-8000-TWIN (B1), it is better to use
UL1015 10AWG (6mm2) cable or any insulated one that com-
plies with the AWG standard for the UPS input and output.
For the model SLC-10000-TWIN (B1) / SLC-10000-TWIN/3 3.
(B1), it is better to use UL1015 8AWG (10mm2) cable or any
insulated one that complies with the AWG standard for the
UPS input and output.
For the models SLC-12000-TWIN/3 (B1) / SLC-15000-TWIN/3 4.
(B1) / SLC-20000-TWIN/3 (B1), it is better to use UL1015
6AWG (25mm2) cable or any insulated one that complies with
the AWG standard for the UPS input and output.
i
Do not use any conventional schuko wall outlet as input
electrical panel because its size is lower than the UPS
current. Combustion danger.
Connect the input and output cables to their corresponding 5.
UPS terminals and according to the model circuit diagram.
i
Tighten the connections.
The protective earth is the connection cable between the 6.
equipment that consumes energy and the earth cable. The di-
ameter of such cable must be, as above stated, as minimum.
The used colour code is green or green with yellow strip.
When concluding the installation, make sure that the wiring 7.
is correct.
Install a circuit breaker to protect the UPS output, if it were 8.
needed.
To connect the load with the UPS, turn off the loads first, make 9.
the connection and, finally, turn on the loads one by one.
Never mind if the UPS is connected to any load or not, voltage 10.
could exist at its output. The internal parts of the equipment
can be life although the UPS is shutdown. To make sure that
there is no output voltage, turn off the UPS and turn off the
input power supply of the electrical panel.
It is better to charge the batteries for 8 hours before using 11.
them. After starting up, turn ON the circuit breaker. The UPS
will charge the batteries automatically. The UPS can be used
immediately without charging the batteries previously, but the
expected autonomy will be lower than the standard value.
In case, it is needed to connect inductive loads to the UPS like 12.
laser printers, the inrush current of such loads should be cal-
culated, in order to determine if the UPS power rate is enough
to supply them.

If the UPS is set on single mode, JP1 and JP2 must be con-
nected with a 10AWG (6mm2) cable. If the UPS is set on
parallel mode, JP1 and JP2 must be disconnected.
