WARNING! If you believe the overcurrent or overvoltage protection circuits have been activated, do not
connect the product power cable or turn on the product power until the cause of the failure is found and
corrected.
In addition, two fuses in the low-voltage power supply protect against overcurrent. If overcurrent flows into
the AC line, the fuses melt and cut off the power distribution.
For safety reasons, the product interrupts power (24 V) to the main motor and high-voltage power supply.
The interlock switch is turned off to interrupt power when the cartidge door opens (SW260 is turned off). The
AC voltage remains present in the product when the power switch is in the off position. Disconnect the power
cable when disassembling the product.
NOTE: An accidental electrical short while servicing the product can result in a loss of power to the product
causing the control panel to shut down (blank out). Turn the product power off, and then unplug the power
cable. Wait at least 15 minutes before plugging the power cable in and turning the product power on.
