Refer to the “Safety prescriptions - Installation” described on Section 1.
4.8.1 Power connections
Carefully read the following recommendations before proceeding:
• Ensure that the AC and DC external isolators are Off, and prevent their inadverted operation.
• Do not close any external isolators prior to the commissioning of the equipment.
• The input/output cables must be put in order and fixed, taking care to avoid risk of short-circuit
between different poles.
• The earthing and neutral connection of the electrical system must be in accordance with local
regulations.
• In case of additional cabinets containing batteries, filters, input/ output transformers, etc, the earth
must be connected to the UPS main earth.
• Once the power cables have been connected, re-install the internal safety shields and close the
cabinets by re-installing all external panels.

NOTE !
To meet standards concerning electromagnetic compliance, the connection between the UPS
and external battery must be done by using a shielded cable or suitable shielded (metal)
conduit!
This UPS is only designed to operate in a wye-configured electrical system with a solidly
grounded neutral.
If the UPS is equipped with an input transformer for galvanic isolation, the secondary of the
transformer must be wye-configured with neutral solidly earthed.
