External motor temperature sensor
(for all units)
Don't install temperature sensor
wires with other control wires.
Must use double shield when running
temperature sensor wires with motor
wires
Braking resistor
Braking resistor
with line side over
temperature cutoff
This is the only
way to turn off
voltage to the
resistor in the
event of failure of the
internal braking
transistor of the inverter.
Braking module
Connection of Power Circuit
On F5 B/G units it is necessary to activate the function through
parameter CP.28.
