TRANSISTORIZED INVERTER INSTRUCTION MANUAL HIGH-DUTY BRAKE RESISTOR FR-ABR-(H)0.
Thank you for choosing the Mitsubishi transistorized inverter option unit. This instruction manual gives handling information and precautions for use of this equipment. Incorrect handling might cause an unexpected fault. Before using the equipment, please read this manual carefully to use the equipment to its optimum. Please forward this instruction manual to the end user.
2. Fire Prevention CAUTION • • Mount the brake resistor on a non-combustible surface. Installing it directly on or near a combustible surface could cause a fire. Use the alarm signal to switch power off. A failure to do so can overheat the brake resistor due to a brake transistor failure etc., causing a fire. 3. Injury Prevention CAUTION • • Ensure that the cables are connected to the correct terminals. Otherwise, damage, etc. may occur.
INSTALLATION INSTRUCTIONS FOR COMPLIANCE WITH UL Install the high-duty brake resistor FR-ABR as follows: • • • • The brake resistor may be mounted horizontally or vertically, depending on a suitable surface location. 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 openings at each end of the resistor.
1. UNPACKING AND CHECKING THE MODEL AND APPLICABLE INVERTERS Take the brake resistor out of the package and confirm that the product is as you ordered and intact. Type FR - ABR - 0.4 K Indicate capacity (kW) Symbol Voltage class 200V class No H 400V class (For the FR-ABR-H15K, a terminal block for connecting resistors is enclosed as two resistors need to be connected in parallel.) FR-ABR-15K is indicated on the resistor. (A type name indicated on the package is different.

2. GENERAL INSTRUCTIONS FOR INSTALLATION (For compliance with UL standard, refer to page A-3.) • Never mount the resistor near wood, paper or any other combustible material. Doing so can cause a fire. • To prevent burns, do not install the resistor in a place where it is readily accessible. If it is easily accessible, mount in a well-ventilated enclosure (e.g. punched metal), suitable for the environment. • Mount the resistor carefully so that the leads do not come from the top of the resistor.
3. INSTRUCTIONS FOR WIRING When the regenerative brake transistor is damaged, the wiring sequence as shown in the following diagrams is recommended to prevent overheating and burnout of the brake resistor.

• Connect the leads of the high-duty brake resistor to the P and PR terminals of the inverter. When using the FR-ABR-15K, 22K, connect two high-duty brake resistors (18Ω) in parallel. When using the FRABR-H15K, connect two high-duty brake resistors (18Ω) in series using a terminal block enclosed.
