2 . 24V
Note: For 22 to 55kW units only, the power supply for the optional dynamic brake
(DB) contactor is made from the control circuit power supply. If DB operation is necessary when the power interruption occurs, maintain the DC24V while the DB operates. If 5 times inertia is attached and a standard DB resistor is used, DB operation
time is approximately 2 to 5 seconds.
