an adequate thermal exchange. Fit the device vertically
(maximum angle 10° to the vertical axis) see figure.
• Vertical distance between a device and the panel
wall >100mm
• Horizontal distance between a device and the panel
wall at last 10mm
• Vertical distance between a device and the next one
at last 300mm.
• Horizontal distance between a device and the next
one at last 10mm.
Check that the cable holder runners do not reduce
these distances, in this case fit the cantilever units op-
posite the panel so that the air can flow vertically with-
out any obstacles.
• dissipation of device thermal power with effects on
installation room temperature.
• thermal power dissipation with limits on installation
room temperature.
• requires exchange with external air or an air con-
ditioner to transfer dissipated power outside the
panel.
• maximum limits of voltage and derived power of
transients on the line, for which the solid state pow-
er unit contains protective devices (based on the
model).
• presence of dispersion current in CFW in noncon-
ducting state (current of a few mA due to RC Snub-
ber circuit to protect the thyristor).
