Specifications

Model 9762 – Dual Combo Owners Manual
3 AC Voltage Select and Safety Fuses
The 9762 may be configured for either 115V or 230V operation at 50 / 60
Hz via the line voltage select card inside the power entry module on the
rear panel. Always disconnect power and remove all connectors from the
unit before servicing or changing the line voltage configuration.
3.1 Internal Thermal Safety Fuses
The +24V status LED’s on each channel show power and regulator
status for that channel. The internal thermal fuse may be in the tripped
state if a channel’s +24V LED fails to illuminate at power up. The thermal
fuses are auto-reset devices and do not require replacement. If a
channel fails to indicate power status, turn the unit off and allow 10
minutes for it to cool down before reapplying power. If power status
continues to fail the unit should be returned to the factory for inspection
and/or repair.
3.2 Line Voltage Select and AC Fuse
To change the AC line voltage selection, disconnect the power plug and
remove the IEC power cord from the power entry module on the rear of
the unit, slide the fuse cover door to the left and rotate the fuse-pull lever
to the left to eject the fuse.
Remove the voltage select card and choose the correct operating
voltage by orienting the voltage selection card as marked. Push the card
firmly into the module slot, rotate the fuse-pull lever back into normal
position and insert the correct fuse type as specified in Table 1 below.
