(2) When not sharing a converter and power supply
If the rated current exceeds 60A by the selection of the circuit protector when the converter and
power supply are shared, install the circuit protectors and contactors separate from the converter
unit.

Install independent circuit protectors and contactors as the SVJ2 main circuit
power supply if the total current capacity exceeds 60A when the converter and
power supply are shared.
DANGER
Circuit protectors may not operate for short-circuits in small capacity amplifiers
if they are shared with a large capacity unit, and this could cause fires. For the
SVJ2, use an NF60 type or lower capacity breaker.
(Refer to section "7-2 Selection of circuit protectors".)
If the converter capacity is more than 45kW or more (MDS-B-CVE-450 or
more), the MDS-B-SVJ2 contactor drive cannot be shared with the converter.
CAUTION
Refer to "2-5-2 Example of connection when controlling the contactor with the
MDS-B-SVJ2" and control contactor 2 from the MDS-B-SVJ2.
