Table 6: Installation procedure
OPERATION
1.
Remove rear covers and connect ac input and output power cables to terminals according to markings as shown
in this User Guide and according to connection schematic.
Verify correct phase sequence between board and UPS
2.
Consult the appropriate connection diagram, depending on the phase configuration of the UPS:
 For 3-3 configuration, see Figure 25 on page 27.

For 3-2 configuration, see Figure 26 on page 28.
 For 2-2 configuration, see Figure 27 on page 29.
Connect ground lines to busses according to markings as shown in the connection diagram.
Verify secure connections.
3.
Connect the dc power cables of the battery cabinets to the UPS terminals according to markings as shown in the
connection diagram (see step 2 above). Connect neutral and ground lines to busses as per the connection
diagram.
Verify correct polarity of the connections (+ / N / -) Between the Battery Cabinets C.B.s / Terminals and the UPS
terminals. Auxiliary contacts of Battery C.B.s are connected to UPS Controller inputs “Bat CB” and “Com” as
marked.
4.
If an external battery cabinet is being used, before turning on the battery cabinet circuit breaker perform the
following two checks:
4.1) Measure the voltage between the (+) and (–) terminals on the battery cabinet. The voltage must
be within the range of 384–432 Vdc. If the voltage is not within this range, determine what the
problem is and resolve it before continuing with system start-up.
4.2) On the battery cabinet, measure the voltage between the (+) terminal and the Neutral terminal, and
between the (–) terminal and the Neutral terminal. Both measurements should be within the range
of 196–216 Vdc. If a reading outside of that range is obtained, determine what the problem is and
resolve it before continuing with system startup.
5.
An external N.O. EPO switch may be connected according to connection schematic.
EPO wiring and switch rating must be rated for at least 1A / 24 Vdc.
6.
Before connecting power to each system, verify again that all connections are secure and are according to
instructions and schematics.
7.
Follow the instructions in section 5.7 "First-time Startup" which begins on page 39.
