No accessible hardware fuse is needed because the main power supply is safe
against any short circuits or overload conditions on the output lines. When
overload conditions occur, the power supply turns off all output voltages.
Turning the line power off and on again resets the power supply to normal
operation if the cause of the overload condition has been removed.
An over-temperature sensor in the main power supply is used to turn off
output voltages if the temperature exceeds the acceptable limit (for example, if
the cooling fan of the quaternary pump fails). To reset the main power supply
to normal operating conditions, turn the quaternary pump off, wait until it is
approximately at ambient temperature and turn the quaternary pump on
again.
The following table gives the specifications of the main power supply.
