4.3.2. Connection to output.
•
As this is a device with class I protection against
electric shocks, it is essential to install a protective
earth conductor (connect earth(
)). Connect the con-
ductor to the terminal, before connecting the power supply
to the input UPS.
•
All the equipments have 2 or 3 schuko outlets depending on the
model.
Also in the 3kVA equipments, there is a group of output ter-
minals.
Loads can be connected to the schuko outlets, or to
the output terminals or to both at the same time, pro-
vided that the power of the equipment is not exceeded, other-
wise there could be sudden breaks in the power supply to the
loads connected to the output.
•
Connect the loads to the outlets schuko.
•
In models with terminal blocks, connect the loads to output
power block U (L) and N, by respecting the phase and neu-
tral rotation stated in the labelling of the equipment.
When discrepancies exist between the labelling and the in-
structions of this manual, the labelling will always prevail.
•
If besides of the critical loads, it is required to connect lag-
ging loads of high consumption, like laser printers or CRT
monitors, the inrush currents of these peripherals will be kept
in mind in order to avoid blocking the equipment under the
worst conditions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.
•
With respect to the protection that must be placed at the
output of the UPS, we recommend that the output power
should be distributed in at least four lines. Each one should
have a circuit breaker protection switch of a value of one
quarter of the nominal power. This type of power distribu-
tion will allow that in the event of a breakdown in any of the
machines connected to the device causing a short-circuit, it
will affect to no more than the line that is faulty.
The rest of the connected loads will have their continuity as-
sured due to the triggering of the protection, because the
line affected by the short-circuit will trip its protection.
4.3.3. Connection of external batteries
(extended back up times) -B1-.
•
As this is a device with class I protection against
electric shocks, it is essential to install a protective
earth conductor (connect earth(
)). Connect the con-
ductor to the terminal, before connecting the power supply
to the input UPS.
•
To not respect the stated indications in this sec-
tion and the safety instructions 1.2.3 means a
high risk of electrical discharge and even the death.
•
All the standard UPSs have batteries in the same enclosure,
less the B0 and B1. Battery protection is done by internal fuses
and not accessible for the end-user.
Battery modules have internal protections for the batteries
too and they are not accessible for the end-user.
•
IMPORTANT FOR SAFETY: In case of installing the
batteries by yourself, the accumulators has to be pro-
vided with a two pole circuit breaker protection sized to the
features stated in table 2.

Features of protection between the equipment and battery cabinet.
•
Before starting the connection between the bat-
tery module/s and the equipment, check that the
equipment switch/es and the one in the battery cabinet
are in “Off” position.
Likewise when batteries are installed by own self, the
fuse or switch has to be turned off.
•
Connection terminals of external batteries with the equip-
ment are done with a polarised Anderson connector. This
connector is not available on standard models.
•
To connect the equipment with the battery module, use the
cable trunk supplied with the module and connect it between
both units and through the Anderson connectors.
When more than one battery module is supplied for one equip-
ment, the connection among the modules will be done through
the cable trunk supplied in the second battery module.
Figure 7 shows as an example, the connection of a SLC-
700-TWIN PRO with "n" battery modules. Less the rear view
of the model, it is applicable to all the range stated in this
manual. Connect the available modules depending on each
case.
•
If for any reason the end-user manufactures the battery cable
trunk, the colour code of the cables has to be respected, red
for positive, black for negative and green-yellow for earth, as
well as the correlation of the connection (+ with +, – with – and
with
).

Each battery module is independent for each equip-
ment. It is strictly prohibited to connect two equip-
ments to one battery module.
