Mitsubishi Inverter Brake Resistor

Installing the inverter directly on or near a combustible surface could lead to a fire.

Mitsubishi inverter brake resistor.

240mm x 50mm x 21mm mounting. Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire. This instruction manual gives handling information and precautions for use of this equipment. A high power factor converter whose.

The brake resistor may be mounted horizontally or vertically depending on a suitable surface location. The wire size used should be minimum 14 awg 2 1mm2. Refer to the instruction manual of the inverter. Mitsubishi inverter option catalog 5 6 a700 1 2 3 regeneration unit option is necessary for regeneration.

Mount the brake resistor on an incombustible surface. The high duty brake resistor cannot be used with a brake unit high power factor converter power return converter built in brake etc. Use the alarm signal of the brake unit to switch power off. This could cause a fire and destroy the inverter.

The brake resistor may be mounted horizontally or vertically depending on a suitable surface location. When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load. Twist the leads of the high duty brake resistor when increas ing their length 2m or more. Increases the braking capability of the inverter which has a built in brake transistor.

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. The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes. 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. Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire.

The inverter without a built in brake transistor can be connected. Via 4 3mm diameter holes. 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. Thank you for choosing this mitsubishi inverter option unit.

Install the high duty brake resistor fr abr as follows. The inverter without a built in brake transistor can be connected. 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. Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw.

Returns regeneration energy to the power supply enabling continuous. The surface temperature of braking resistors can far exceed 100 c for brief periods. Increases the braking capability more than the brake resistor.
