Mounting screws
If possible, the two uninterruptible power supplies should not be connected to
the same power source.
Attention: Ensure that you comply with the following requirements for
uninterruptible power supplies:
v Each UPS 5115 should be connected to a separate branch circuit.
v A UL listed 15 A circuit breaker must be installed in each branch circuit that
supplies power to the UPS 5115.
v The voltage supplied to the UPS 5115 must be 220 – 240 V single phase.
v The frequency supplied must be between 50 and 60 Hz.
Note: If the UPS is cascaded from another UPS, the source UPS must have at
least 3 times the capacity per phase and the total harmonic distortion
must be less than 5% with any single harmonic being less than 1%. The
UPS must also have input voltage capture that has a slew rate faster
than 3 Hz per second and 1 msec glitch rejection.
6. At the back of the UPS 5115, plug the UPS 5115 main power connector
1
into
the power socket. The UPS 5115 will be in standby mode so all indicators will
be off. See Figure 13 on page 40.
Note: The UPS 5115 is intended to maintain power on SAN Volume Controller
nodes until data can be saved to the local hard disk drive. Only SAN
Volume Controller nodes can be plugged into the UPS 5115 or the SAN
Volume Controller cluster malfunctions.
