4.8 WIRING CONNECTION
WARNING !
UPS installation and connection must be performed by QUALIFIED SERVICE
PERSONNEL only.
Refer to the “Safety prescriptions - Installation” described on Chapter 1.
In case of UPS equipped with options or customized parts not covered by this
manual, please consult the appropriate technical documentation before proceeding
with electrical 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 connected in clockwise phase rotation for both Bypass and
Rectifier Input Bars if separate, taking care to avoid risk of short circuit between different poles.
The grounding and neutral connection of the electrical system must be in accordance with local
regulations.
In case of additional cabinets containing batteries, input/ output transformers, etc, their ground
terminals must be connected to the UPS main ground terminal.
Once the power cables have been connected, re-install the internal safety shields and close the
cabinets by re-installing all external panels.
