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 24
, 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.
