The DC dynamic braking components have been sized for occasional non-repeated use, assuming load inertia is equal to or less than motor inertia. The dynamic resistor will be

sized at approximately 150% of rated motor current. The DC drive will also require a DB contactor option for dynamic braking action.

Note: NEMA 1 Enclosure is galvanized steel. DB resistors are shipped loose for mounting at least twelve inches from drive enclosure.
