The UPS is designed to be installed in an environment that
meets the following classifications.

Tabla 10.
Characteristics of the location of the device.
If the environmental conditions of the installation location do
not meet the indicated requirements, it will be necessary to
take additional precautions to reduce values in excess of the
specified limits.
5.2. CONNECTIONS.
•
A bad connection or switching operation can cause faults
in the UPS and/or the loads connected to it. Read the
instructions in this manual carefully and follow the steps
indicated in the order established.
The devices can be installed and used by personnel
without specific training simply with the help of this
manual.
It should never be forgotten that a UPS is a generator
of electrical energy, and, as such, the user must take
all necessary precautions against direct or indirect contact.
All of the device’s connections, including those
related to control (interface, EPO, etc.), must be
made without mains power present and the UPS set to ‘Off.’
•
To connect a device to an optional battery module, or
between modules, or to install an optional card in the slot,
it is necessary to remove its respective protective metal
cover screwed to the UPS. Remove the screws and cover.
5.2.1. Connection to the mains.
For electrical connection of 80... 400 kVA devices to the mains,
connect the following cables:
•
AC power from the rectifier and the bypass power supply.
•
AC output of the loads.
Risk of damage to the device due to insufficient
isolation.
The cables must be protected against short-circuits and current
earth leakage.
The connection points must be hermetically sealed to prevent air
from being sucked into the ducts where the cables are housed.
Risk of damage to the device due to incorrect
wiring.
To connect the device, follow the electrical diagram carefully
and respect the polarity of the cables.
