Verify that appropriate sized circuit breakers are
present on the electrical boards supplying the
Centric. Read Chapter 8 in this Installation Guide.
Refer to Figure 8 or Figure 9. Refer to Table 2 and
Table 3.
Verify that the cables between the electrical board
and the UPS, and between the UPS and its loads,
and also the ground/PE cables, are of appropriate
sized input and output power. Refer to Figure 8 or
Figure 9, and see Table 2 for amperage of rectifier
and bypass input lines.
Verify ac input voltages.
Verify the voltage between neutral and ground.
Verify dc voltage at battery cabinet switch.
Verify that neutral is always connected.
Verify that the circuit breakers on the electrical
board for the UPS ac input, bypass input and
output lines are in the "OFF" position.
Attach ac input, bypass ac input, and output cables
to the Centric (refer to Figure 8 or Figure 9).
Attach the cable stress reliever
Assemble and connect the batteries within the
battery cabinet, verify proper voltage.
Verify that the connection of the battery to the UPS
is according to the diagram and instructions in
section 3.2.4.5.
FAST FUSES (SEMICONDUCTOR FUSES)
must be used between the battery and the
Centric.
For example, the Bussmann "FWH" fuse.
Verify that there is a switch or other means to
easily and safely disconnect the battery cabinet
from the UPS in the event of an emergency or for
maintenance.
With the battery circuit breaker "OFF", connect the
battery cable to the UPS. Leave the battery circuit
breaker "OFF".
Locate the cable for the LCD display screen – it
should be projecting out from the top front of the
UPS near the mounting post of the LCD screen.
Attach the LDC display screen to the top front of
the UPS, then connect the cable to its right side.
Power-up the system.
Perform the initial configuration.
Complete first-time startup.
If you are using lithium-ion batteries, verify that
the battery setup parameters (Setup > Battery) are
appropriate for the batteries you have chosen.
Perform post-startup tests.
