Safety statements
Output power and ampere ratings
Important: Make sure that the power receptacle is near the equipment and is easily
accessible so that the uninterruptible power supply (UPS) can be
disconnected quickly.
To reduce the risk of fire, connect only to a circuit provided with branch circuit over-current
protection with an ampere rating in accordance with the National Electrical Code (NEC),
ANSI/NFPA 70 or your local electrical code.
Product Safety
The UPS connection instructions and operations described in the manual must be
•
followed in the indicated order.
Important:
•
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-certified 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.
6U Rack or Tower UPS RT8kVA and RT11kVA IUOMG
To reduce the risk of fire, the unit connects only to a circuit provided with
