The brake resistor may be mounted horizontally or vertically depending on a suitable surface location.
Mitsubishi inverter brake resistor.
When the brake resistor is mounted externally to the enclosure housing the inverter install a solid type 1 enclosure at least 8 times the volume size of the brake resistor that incorporates mesh or perforated steel type ventilation.
Do not connect a resistor directly to the dc terminals p and n.
Returns regeneration energy to the power supply enabling continuous regeneration operation.
Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw.
The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes.
Via 4 3mm diameter holes.
Installing the inverter directly on or near a combustible surface could lead to a fire.
If you are purchasing a braking unit from mitsubishi you can find your appropriate resistor by looking at the brake resistors for brake units table.
Install the high duty brake resistor fr abr as follows.
Increases the braking capability of the inverter which has a built in brake transistor.
Mount the brake resistor on an incombustible surface.
Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire.
Twist the leads of the high duty brake resistor when increas ing their length 2m or more.
Some drive models come come with a large brake transistor built in you can find their minimum resistance and max braking power in the drives with internal braking transistors table.
Returns regeneration energy to the power supply enabling continuous.
A high power factor converter whose.
Mitsubishi inverter option catalog 5 6 a700 1 2 3 regeneration unit option is necessary for regeneration.
Increases the braking capability more than the brake resistor.
Refer to the instruction manual of the inverter.
Thank you for choosing this mitsubishi inverter option unit.
When the brake resistor is mounted externally to the enclosure housing the inverter install a solid type 1 enclosure at least 8 times the volume size of the brake resistor that.
Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire.
Use the alarm signal of the brake unit to switch power off.
For use with fr d720s and fr e720s series inverters rated at 1 5kw or 2 2kw.
This instruction manual gives handling information and precautions for use of this equipment.
The wire size used should be minimum 14 awg 2 1mm2.
The surface temperature of braking resistors can far exceed 100 c for brief periods.
240mm x 50mm x 21mm mounting.
When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load.
This could cause a fire and destroy the inverter.
The inverter without a built in brake transistor can be connected.
