V2.1
For 480V PTE models (PTE4XX), disconnect wires from JL2. You may need to remove the
baffle covering the heatsink to access JL2. Next, use a multi-meter to measure between L1
and L2, then measure between L2 and JL3B. If either capacitance measured is below the
50% Capacitance value in Table 26, contact Phase Technologies for replacement. Be
sure to reconnect wires to JL2 before powering unit on again.
Fuses
There are several replaceable fuses in the converter. Each fuse is assigned a designator,
indicated by its label. Contact the Phase Technologies Service Department for replacement
fuses.
