ALS-1300SPS Interconnect Diagram
AC Mains Selection
There are two different power supply modules that may be used in the ALS-1300/ALS-
1306/ALS-1406 power supply with different wiring to switch the power supply between
240 and 120 VAC. Identify which power supply module is used before trying to change
the input voltages. Make sure the power supply is unplugged before removing the cover
from the power supply. If the power supplies are changed to 120 VAC do not plug into a
240 VAC source. They will fail.
