CAUTION
Overcurrent protection is not provided by this product, but is required by
codes. Refer to Table
for wiring requirements. If an input/output lockable
disconnect is required, it is to be supplied by the user.
Rectifier input and bypass input overcurrent protection is to be provided by the
user and installed in the immediate vicinity of the UPS. A readily accessible
disconnect device must be incorporated in all fixed input wiring. If the optional
input and bypass input switches are not chosen, input and bypass input
disconnect devices are to be provided by the user and installed in the immediate
vicinity of the UPS.
Output overcurrent protection and bypass and output disconnect devices are to
be provided by the user and installed in the immediate vicinity of the UPS.
Table
lists the recommended rating for input, bypass input and output circuit
breakers for rated conditional short-circuit current of 10 kA. Table
lists the
recommended fuse types to be installed with supplies capable of providing
conditional short-circuit current up to 65 kA.
Battery voltage is computed at 2 volts per cell. Rated battery current is
computed at 2 volts per cell.
There is no DC disconnect device within the UPS. A battery disconnect switch is
recommended, and may be required by local codes when batteries are remotely
located. The battery disconnect switch should be installed between the battery
and the UPS in the immediate vicinity of the UPS.
External DC input overcurrent protection and disconnect switch for a remote
battery location is to be provided by the user. Table
rating for continuous-duty rated circuit breakers satisfying the criteria for both.
