X75-RCP Fuse Rating and Replacement
The X75-RCP input is protected by a 2A slow blow fuse, located in the
AC power supply.
CAUTION
To avoid the risk of fire, you must always replace the fuse with the
same type of fuse and specified rating. Failure to comply may result
in equipment damage and/or personal injury.
In rare cases, it may be necessary to change the power supply fuse.
However, a blown fuse indicates the presence of a serious electrical
fault.
To access the power supply fuse, follow these steps:
1. Remove the AC power cord and Ethernet connection from the back
of the control panel.
2. Remove the control panel’s mounting screws.
3. Remove the four screws on the top of the unit, and then remove the
flat panel cover.
4. Locate the fuse in the power supply and then remove it.
5. Replace the fuse with another 2 A 250 V 20 mm cartridge fuse.
6. Re-install the flat panel cover.
7. Re-connect the AC power supply and Ethernet connection.
