Note: The 200 kvar (SVGm-3WF-200C), 300 kvar (SVGm-3WF-300C) and 400 kvar (SVGm-3WF-
400C) cabinets are made up of 2, 3 and 4 100 kvar devices in parallel.
The 138 kvar (SVGm-4WF-138C), 207 kvar (SVGm-4WF-207C) and 276 kvar (SVGm-4WF-276C) cab-
inets are made up of 2, 3 and 4 69 kvar devices in parallel.
The 134 kvar (SVGm-4WF-134C), 201 kvar (SVGm-4WF-201C) and 268 kvar (SVGm-4WF-268C) cabi-
nets are made up of 2, 3 and 4 67 kvar devices in parallel.
