ROUTINE INSPECTION AND MAINTENANCE
HIGH VOLTAGE: This equipment is connected to line voltages that can
create a potentially hazardous situation. Electric shock could result in serious
injury or death. This device should only be installed and serviced by trained and
licensed personnel. Follow instructions carefully and observe all warnings.
WARNING! Under certain operating conditions, the converter will shut down
and automatically restart. Always disconnect input power from the unit and wait
30 minutes for charge to dissipate before performing service on the converter or
connected loads.
The converter should be inspected and cleaned annually or more frequently if located in a
hot or dirty environment. Special attention should be given to the following:
Power terminals: Periodically, inspect for loose connections and tighten to specifications
in Table 6, Table 7, Table 8, Table 9 and Table 10 .
Capacitors: Check for leakage or deformation.
Overall: Perform visual inspection, checking for things such as discolored wires or
terminals, evidence of arcing, loose mounting screws, physical damage to the enclosure,
etc.
Fans and heatsinks: Excessive dust buildup on heatsink or fan impellers may lead to
overheating. Lightly brush and vacuum.
Contact Customer Service for assistance in replacing cooling fans. Use only fans approved
by Phase Technologies. Unapproved fans may lead to component damage.
Line Filter Capacitors
Line filter capacitors are part of the inductor/capacitor (L/C) filters and should be routinely
monitored and replaced if degraded. Failure of the L/C filter can lead to increased harmonic
levels, which may damage equipment connected to converter.
The capacitors can be observed by opening the front door of the converter. See
Figure 18
- Figure 20 to identify the line filter capacitors.
