5.8.1 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 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
regulation.
•
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 (steel)
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 bypass transformer, the secondary of the
transformer must be wye-configured with neutral solidly grounded.
