5.5 Configuring the Input/Output Voltage

The input and output voltages are factory configured to your specifications. You can change
them with this procedure.
DANGER: Lethal levels of voltages and currents are inside the unit when it is con-
nected to line and battery power. All circuit breakers on the rear panel must be turned off
before starting this procedure.
Procedure:
1
Confirm all the rear panel circuit breakers are switched off.
2
Remove the unit's top cover as shown in Section 2.3, "Connecting the Internal Batteries,"
Step 1, "Open the Unit."
3 Find the high voltage board on the top
shelf (labeled as "700–219–XXX").
Also see Figure 5.2.
4
Find the AC input terminal block.
Move the wire to the desired voltage.
TIP: All wire strands must be
inside the terminal block. Strands
sticking out are a safety hazard.
5 Find the AC output terminal block.
Move the wire to the desired voltage.
TIP: All wire strands must be
inside the terminal block. Strands
sticking out are a safety hazard.
