3.2. Fuse Specifications
WARNING
: Replace fuses only with the same type and value.
Always disconnect the Mains power connection before opening the XR3 chassis. Fuses must not be
changed with Mains power applied to the unit.
The fuses on the drive interface board are factory-configured based on the bus voltage configuration
that you ordered. The fuses are not likely to blow under normal operating conditions.
The most likely reason for a fuse to blow is if you have connected the unit to the wrong AC line voltage.
