Braking resistors
• All 7200MA model have built-in
braking transistor as standard. If
more braking capacity is needed, the
external braking resistor will be used.
• The 7200MA (1-5HP standard type,
except compact size type) can have
an external braking resistor attached
on the back of heat sink of inverter.
