Replacing a Fuse on 2U Models
This section introduces how to replace a fuse on a 2U model.
To order replacement fuses from Raritan, see Technical Specifications (on page
721) for correct fuse types.
Replacing a "blown" fuse can be performed while both inlets remain connected
to power.
To replace a fuse:
1. Identify the bad fuse by checking the fuse status using the LCD display or
web interface.
2. Examine your PX3TS and the connected equipment to remove or resolve
the cause that results in the overload or short circuit.
This step is required,
or you cannot proceed with the next step.
3. When you are sure the overload does NOT exist, you can force transfer to
the inlet with the good fuse to restore the current output to outlets. See
Manual Transfer When an Alarm is Present (on page 114).
▪
In case the good fuse blows after manual transfer, stop and repeat
Step 2.
4. This step is recommended but not required -- disconnect the inlet with the
bad fuse from power.
5. Locate the bad fuse's holder on the rear panel.
6. Open the fuse cover.
7. Remove the fuse inside the holder and re-install a new one. Make sure the
new fuse is identical to the original one.
8. Close the fuse cover and verify that it is firmly closed.
