3.
Ensure that the circuit breakers in the user’s AC electrical service panel are Off..
4.
Disconnect all loads from the system by turning Off all load breakers.
5.
The Rectifier On/Off breaker of each Rectifier, is set to Off. See Figure 2-4.
6.
Turn On power to Rectifier 1.
The top-most left Rectifier in the stack will perform a power-up self-test lighting the three LEDs on the rectifier. After a brief
period, the red and yellow LEDs will extinguish and green LED will remain lighted (Float mode). Refer to the following note and
to Section 6.3 Troubleshooting should the red or yellow LEDs remain lighted.
Yellow LED Note:
When starting the System for the first time, it may be necessary for the rectifiers to supply significant current
for initial battery charging. A lighted yellow LED on a rectifier may not be due to a rectifier problem but rather indicate that the
rectifier is operating in the over-current mode due to a discharged battery string. If this is the case, continue with the procedure to
bring additional Rectifiers on-line.
7.
Read the rectifier current and voltage on the operator panel 2-line display. The Red
LED on the panel will be lighted unless the number of operating Rectifiers equals
the number of Rectifiers in the System configuration, in which case the Green LED
will be lighted. Refer to Section 6.3 Troubleshooting as needed.
8.
Connect a 10 to 50A load to the System through a distribution breaker or fuse. Refer to Chapter 4 Configuration and Operation
and use the operator panel push buttons and menus to:
1)
Turn Off battery temperature compensation. (Note: If the float voltage is set at high or low battery temperature with battery
temperature compensation turned On, compensation may adjust the System voltage by as much as 2 volts.)
2)
Connect the load to the System by closing the distribution breaker.
9.
Repeat Steps 7 through 10 until all Rectifiers are on-line and taking load. As Rectifiers are brought on-line, the load may be
increased.
10.
At the operator panel, verify that each Rectifier is sharing current and the Sageon III Power System voltage is set to the desired
Float voltage, generally –54.2 Vdc ±½ volts.
11.
Configure the Sageon III Power System as described in Chapter 4 Configuration and Operation. If the configuration has been
created on a PC and is to be uploaded to the operating Sageon III Power System, also refer to Chapter 5 SageView.
12.
Thoroughly test the new configuration to ensure that all configurable parameters are correct. Test the alarm circuits to ensure
correct activation.
13.
As needed, operate the system for 15-20 hours to charge the battery string(s) before placing the system on-line.
3.3 OVERVIEW OF EXTERNAL WIRING CONNECTIONS
SD-SAGEON3.AXX drawings show the internal and interface schematic for the Sageon III Power plant with distribution. For the
purpose of indicating how a system is connected, the same schematic applies to other Power plant products.
The system shown is for a –48V system where the positive side of the DC bus is tied to ground, usually on the common return bar. It
is also possible to float the output, but under these conditions, there is no guarantee that all voltages on the DC bus will stay below the
Safety Extra-Low Voltage (SELV) limits with respect to ground during fault conditions.
3.4 FACTORY SUPPLIED CONFIGURATIONS
Power plant internal AC distribution, are configured with each rectifier AC line being terminated in an individual block terminal. The
grounding wire connects to the block terminal.
Single phase – individual protected external feeds
Connect each of the circuit breaker protected phase wires to the individual terminal blocks, labeled L1, that feed each rectifier.
Connect the neutral (or phase 2) wires to the terminal labeled L2 for each rectifier.
