Inverter Module Installation and Operation
3-10 TM-DIOP-01XN-01
Fuses and Grounding
The inverter is equipped with non-user replaceable, internal fuses for fault
protection. The input fuse (fuse F1) is rated at 60 A, 170 Vdc, 100 kA 1R
and positioned in the return path. Both L1 and L2 output ports are
protected with slow acting fuses (fuses F2 and F3). The fuse ratings are
model dependant and as follows:
XDI2048 120 V output: 20 A 250 V
XDI2048 230 V output: 12 A 250 V
Grounding studs are provided adjacent to the DC input and AC output
ports. The equipment must be grounded at these locations as required by
end applications and local regulations. See Chapter 2, “Rack Mount
Frame Assembly and Installation” for connection details.
Incorrect Connection Protection
• Input contactor will not close for normal startup with reverse polarity
input connection.
• The output contactor will not close if AC back feed is detected on
power up or if a unit is unable to synchronize to the AC bus.
• The output fuse will open for output faults not covered by internal
protection circuitry.
Output (AC) Alarm
The following conditions will cause an output alarm:
• Output overload
• Output short circuit
• Output Over-voltage
• Over-temperature
• Module failure
When such a condition exists,
1. The red FAULT indicator located on the front panel is turned on,
2. The open collector “Fault” alarm output is energized,
3. The output contactor is opened and the inverter output is disabled.
Except in the case of an Output Overload when the module will
continue to run for a short period, depending on the overload power,
prior to shutdown.
