OPTIONS

11.4 ACS PCB.

To be installed on the slot "L", it synchronises UPS output with an external power source (another UPS, even of a
diff erent brand, generator or transformer).
11.5 ADC CARD WITH TEMPERATURE SENSOR.
This card can be used to manage up to four normally closed or normally open outputs and up to three digital inputs in
confi gurable mode. If more than one ADC card is used simultaneously, the dip-switch confi gurations must be diff erent.
Secure the card with the appropriate screws.
11.6 EXTERNAL BACK-FEED PROTECTION.
External devices can be installed to protect against the backfeed of dangerous currents, both on the MAINS SUPPLY
and on the AUX MAINS SUPPLY.
These devices have to be connected to the terminals provided (see picture 11.6-1).
Refer to the following paragraphs for details on the electrical connections and on activating the chosen protec-
tion.
Attention.
In some failure conditions (earth leakage, signifi cant phase dispersion or in case of non-isolated neutral system), high
potential can be detected in the neutral. It will therefore be necessary to install either adequate neutral switching
or protection system.
