SIVACON S8 Planning Principles – Reactive power compensation
fuse and connecting cable must be factored in. For their
configuration data, please refer to Tab. 7/5.

1) For this type of protection the information plate "Caution, reverse voltage through parallel cable" is recommended. A circuit-breaker can be used to avoid the
problem with parallel fuses.
2) Connection possibility for separately installed compensation cubicles: up to 2 x 240 mm 2 .
Recommendation for 4 parallel cables per phase: Use separate incoming feeder cubicle and power factor correction cubicle with main busbar.

compensation cubicles

compensation cubicles
When compensation cubicles are configured, which are to
be installed separated from the switchboard, the back-up
