SVGm IP54

3.5.- CONNECTION

For the cabinet's power supply, a cable with a cross-section suitable for the maximum
current that can flow through the device must be used. Although the device is com-
posed of 67, 69 or 100 kvar modules, to make installation easier, the modules are al-
ready wired, and the user only has to take into account the device's total capacity. The
recommended minimum cross-sections are
SVGm-4WF-067C-550: 35 mm
SVGm-3WF-100C-480 and SVGm-4WF-069C-400: 70 mm
SVGm-3WF-100C-690: 50 mm
SVGm-4WF-134C-550: 70 mm
SVGm-3WF-200C-480 and SVGm-4WF-138C-400: 70 mm
SVGm-3WF-200C-690: 95 mm
SVGm-4WF-201C-550: 120 mm
SVGm-4WF-268C-550: 150 mm
SVGm-3WF-300C-480 and SVGm-4WF-207C-400: 150 mm
SVGm-3WF-300C-690: 150 mm
SVGm-3WF-400C-480 and SVGm-4WF-276C-400: 240 mm
SVGm-3WF-400C-690: 240 mm
Neutral conductor cross-section must suit the expected neutral current and must be
selected according to the external protection devices.

These sections are for informative purposes only. The conductor cross-section must be selected according to the current,
prevailing regulations, cable type and type of wiring installation.
Ensure that the SVGm IP54 is earthed correctly to prevent the risk of electric shock.
To measure the current, class 0.2S transformers of the TC or TCH series are recom-
mended.
The use of transformers with ratios close to the current to be measured is recommend-
ed.
The correct connection of the current transformers is vital for the SVGm IP54 static gen-
erators to operate properly. If the phases L1, L2 and L3 are switched in the secondary,
the static generator will not work properly.
The SVGm IP54 devices have built-in fuse overcurrent protection.
Install external protection according to the type of installation, the facility's maximum
short-circuit current, the maximum fuse current, and the regulations in force at the
place of installation.
If local regulations require the use of earth leakage protection devices, only DC sensitive
RCD (RCD type B) should be used with SVGm IP54. Static generators work internally
with DC currents, and, in case of failure, the DC currents may produce malfunction on
type A RCD devices.
