Goodrive350 IP55 High-ingress Protection Series VFD
 Connect braking resistors only to the terminals PB and (+), and braking units
only to the terminals (+) and (-). Do not connect them to other terminals.
Otherwise, damage to the braking circuit and VFD and fire may be caused.
Connect the braking components to the VFD according to the wiring diagram. If the
wiring is not properly performed, damage to the VFD or other devices may be
caused.
The 037G/045P and lower models are equipped with built-in braking units, and the
045G/055P–110G models can be configured with optional built-in braking units. Select braking
resistors according to the specific requirements (such as the braking torque and braking usage)
on site.
