DANGER
Performing the following procedure exposes the servicing technician to
hazardous voltages and will disrupt power to the system loads. The
servicing technician MUST verify that AC and DC input sources to the
power supply have been removed. If system power must be maintained
during output voltage reconfiguration, connect the output from a service
supply to the power insertion point of the cable before proceeding.
1. Perform Steps 1) and 2) of the shutdown procedure appearing in Section 7) of this
manual.
2. If necessary, ensure that power to the cable system is being provided by a service
supply. Verify that the AC input cord of the power supply has been disconnected
from its receptacle.
3. Disconnect the output cable from the power supply, then remove the left-side front
panel. Retain all mounting hardware.
4. Place the output voltage select wire shown in Fig. 9-1 and 9-2 into the appropriate
voltage connection terminal of TB2. Select the 60, 75 or 90-volt position as
required per system needs. Tighten the terminal board screw to secure the
voltage select jumper wire in place.
5. Replace the left-side front panel and fasten into place using the hardware retained
from Step 3).
6. Reconnect cables to the power supply and inverter module as required, then
restart the power supply according to the procedure contained in Section 6) of this
manual. After the power supply has been restarted, remove the service supply to
complete this procedure.
Input Voltage Configuration:
Your power supply has been manufactured, equipped and tested for the input voltage
specified on the original order, either 120 or 240 volts AC. Since certain hardware
changes and recalibration would be required, reconfiguring the power supply for a
different input voltage is not recommended as a field modification. Input voltage
reconfigurations, where and when required, should be installed only at qualified
service centers or repair facilities.
In emergency situations, where input voltage reconfiguration must be carried out for
temporary operations, perform the following procedure:
