REX062 input protection
REX062 limits overvoltage by a varistor at the injection output to stator. Normally , REX060 will
interrupt the injection circuit in case of excessive over-current in the injection chain. Fuse within
REX062 is an additional protection in case of failure within REX062 during over-voltage condition.
A blown REX062 fuse requires a module disassembling to replace the fuse (F 6.3 A 250 V).
However, if this occurs it is recommended to identify the reason for the over-current and do
needed actions to reduce the current.
