67 5 Maintenance
5.5 Configuring the Input/Output Voltage
The unit is factory configured to your input/output voltage specifications.
• Units configured only for 120 VAC input and output voltage need a new high voltage
board installed before re-configuring the input or output voltage. Contact Alpha Technolo-
gies customer service department.
• Units configured for 230 VAC, 50 Hz input and output cannot be re-configured.
• Units configured for 208 VAC or 240 VAC input voltage can be re-configured to 208 VAC
or 240 VAC input voltage.
• Units configured for 120/208 VAC output or 120/240 VAC output can be re-configured to
120/208 VAC or 120/240 VAC output.
DANGER: Lethal levels of voltages and currents are inside the unit when it is con-
nected to line and battery power. The Input and Battery circuit breakers on the rear
panel must be switched off before starting this procedure.
Tools and Materials Required:
• Phillips and Slotted Screwdrivers.
Procedure:
1 Turn off all loads. Make sure the Input and Battery circuit breakers on the rear panel are
switched off.
2 For the CFR 3000, remove the front panel and the cover as described in Step 1 of Section
5.4. Find the high voltage board labeled as “700–226–XX” (Figure 5.4).
