2. UNPACKING AND INSTALLATION OF THE UNIT
2.6.7. Completion of the installation
2.7. GENERATOR CONNECTION
If the installation requires the use of a generator (GE), connect the ‘generator ready’ unpowered contact to connector IN 2 of the
ADC card confi gured in STANDARD confi guration (see paragraph 7.2). This allows the tolerance of the voltage and frequency
values to be increased when power is supplied by the GE.
2.8. EXTERNAL ESD CONNECTION
An emergency remote shutdown system (ESD) can be installed using the ADC card (see paragraph 7.2). Connect a normally
closed, unpowered contact to terminals IN1+ and IN1- of the ADC card.
2.9. ISOLATION TRANSFORMER
If an external isolation transformer cabinet is required, the following instructions should be followed:
• Refer to chapters 1 and 2 of this manual for indications on moving and installing the cabinet.
• See paragraph 2.5 for details about protection.
• The protection cable marked with the ground symbol is connected directly to the distribution panel.
• The transformer can either be connected to the UPS input or output.
The UPS must not operate without the neutral connection to the input.
The transformer cannot be connected to the output on individual UPS units connected in parallel configuration.
For connection details refer to the transformer terminal board diagram.
