5. If the Simple-H is coated with conformal PCB coating products please ensure the
heatsinks are masked and left free of coating.
6. Monitor the terminal connectors especially if fork type terminals are used. It is possible
for them to twist and come in contact with the filter capacitor. If the filter cap is too
close to the B+ and B- terminals it may be gently pushed back toward the heatsinks. It
should have some clearance and not press tightly against the heatsinks because
vibration may wear through the plastic coating and cause a short circuit. Tighten all
screws securely and use thread locker if needed to ensure the terminal screws remain
tight. Note, if the M1 and M2 connectors do twist and contact the heatsink that is not a
problem since they are electrically connected anyway.
7. Attempting regeneration while the battery is fully charged may lead to larger than
expected voltage rise at the battery possibly exceeding the maximum for the Simple-H.
Many batteries have significantly increased impedance when fully charged. This can
cause a large voltage spike when attempting to flow current into the fully charged
battery. Once the battery has discharged some its impedance to reverse current
should be much lower and regeneration can safely be used.
