Product Safety

The UPS connection instructions and operations described in the manual must be
•
followed in the indicated order.
Important: To reduce the risk of fre, the unit connects only to a circuit provided with
•
branch circuit over-current protection as described in this manual, in accordance with
the National Electric Code, ANSI/NFPA 70.
The upstream circuit breaker for Normal AC and Bypass AC must be easily accessible. The
•
unit can be disconnected from AC power source by opening this circuit breaker. This
circuit breaker is used for back-feed protection and must comply with IEC/EN 62040-1
(the creepage and clearance distances shall meet the basic insulation requirements for
pollution degree 2).
Disconnection and over-current protection devices shall be provided by others for
•
permanently connected AC input (Normal AC and Bypass AC) and AC output circuits.
Check that the indications on the rating plate correspond to your AC powered system
•
and to the actual electrical consumption of all the equipment to be connected to the
system.
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment
•
and shall be easily accessible.
Never install the system near liquids or in an excessively damp environment.
•
Never let a foreign body penetrate inside the system.
•
Never block the ventilation grates of the system.
•
Never expose the system to direct sunlight or source of heat.
•
If the system must be stored prior to installation, storage must be in a dry place.
•
The admissible storage temperature range is -15° C (5° F) to +50° C (122° F).
•
This unit is not designed to conform to ANSI/NFPA 75 and therefore is not for use in
•
ANSI/NFPA 75-certifed data centres.
Although the UPS does not contain back-feed (ABF) relays, some back-feed protection is
•
provided. For example, if some components are damaged in battery mode, the output
voltage may feed back to the input. In this case, a current transformer (CT) is used to
detect the bypass current feedback voltage. If a current back-feed fault condition is
detected, the UPS will terminate the inverter output to avoid personal injury.
