Caution Please strictly observe safety precautions described below to prevent personal injury and property damage. Instruction Manual Contactless Brake Unit for Small Geared Motors MB48X Series Model: DVMB48XZ Risk of electric shock, injury or fire Don’t make soldering joint on a round pin of the brake unit. Don’t use the unit in an environment where large amount of static electricity or charges are obtained. Don’t damage leadwires; don’t subject leadwires to excessive stress such as strong pressure, heavy object and clamping load; don’t soak leadwires in oil or water. Don’t lock the motor shaft while it is running. Don’t start or stop the motor by turning on or off the main power. Don’t touch rotating member of the motor while it is running. Don’t touch potentially hot motor casing. Don’t use the unit when it is damaged. Don’t get on the product. Don’t place heavy object on the product. Don’t attempt to perform modification, dismantle or repair. Test-run the securely fixed motor isolated from mechanical system to verify normal operation (e.g. rotating direction), and then install it to the machine. Securely install the equipment to prevent bodily injury or fire in case of earthquake. After correctly connecting leadwires, insulate the live parts with insulator. Always keep power disconnected when the power is not necessary for a long time. After an earthquake, first verify safety. Once power failure occurs or the overtemperature protecting device activates, don’t come close to the machine that will unexpectedly start upon recovery of the power. Provide secure mechanism so that the restarting of the machine will not cause personal injury. Repair must be performed by Panasonic authorized service shop. Before installing, transferring, wiring or mechanically checking product, disconnect the power source. The product must be disposed as industrial waste. ■The below explains what will happen if someone fails to heed a particular precaution statement.

Lights when motor is turning counterclockwise when viewed from output shaft. Lights when the electric brake is operating. Lights when the electromagnetic brake is energized, releasing braking. Adjust the operating time of electric brake in response to inertia of the load. For normal braking operation, minimum setting of 0.2 s will do. Since a longer braking time will cause the motor to become hot, shortening its life, the time should be the minimum possible value. The motor frame temperature must be kept below 90 ℃. To increase the braking torque, turn the knob CW. For a motor sized between 40 W and 90 W, adjust the torque within the range indicated by the black arrow. Setting beyond the limit will cause malfunctioning or shorten the life of product. −4− 80 min. Installation location Considerations on power supply Avoid the following locations: ・Place where the product will be exposed to direct sun light for a long time (e.g. outdoor). ・Place where the product will be subjected to excessive vibration or shock (5.9 m/s2 or more). ・Place where the product will be exposed to nonnegligible amount of dust and humidity. ・Place where the product will be exposed to flammable gas or corrosive gas. ・Place where large amount of static electricity will generate (near forming, powdering or fluid processing facilities). ・Place where the product is exposed to high electrical field (near radio transmitting device or welder). Provide appropriate shield as necessary. ●When unauthorized person can access the unit, install it in a lockable control board. ●When the unit is installed in the control board, do not place flammable material near the unit. ● Be sure to turn off power when it will not be used for a long period. When using a transformer or variable transformer, its capacity must be larger than the rated power input of the product, to assure reliable operation. ● ● Operating precautions The motor housing temperature must be kept below 90 ℃. The motor frame temperature depends on ambient temperature, loading condition and start/ stop cycles. When the frame temperature exceeds 90 ℃, replace the motor with a larger size motor. (Measure the motor frame temperature by using thermometer, thermocouple, thermo-tape, etc.) ●The number of start/stop operations should be 6 times/min or less. ●One brake unit must be connected to only one motor. ● Considerations on chemical, oil and water Do not use the product in atmosphere containing organic solvents such as alcohol, benzin and thinner; oils such as cutting oil and grease; or strong alkaline materials such as ammonia and caustic soda. ●Prevent intrusion of water or oil. The product is not waterproof. ●Do not operate the unit with bare hands. ● Considerations for wiring Use a terminal block or socket for wiring connection. Do not solder the lead to the round pin. ●When wiring or connecting the unit to the terminal block or socket, turn off power. ●The brake unit is not provided with a protective device: Use overcurrent protection device, ground-fault circuit interrupter, and overtemperature protecting device. ●Wrong wiring will damage the brake unit or cause motor burnout. ●Do not run cables and wirings of the unit in the same or in parallel with those of high capacity electric furnace or welder which controlled by the thyristor, or any other high- power/frequency equipment. Induced noise voltages will cause malfunction. ●In buildings (e.g. mountain lodge and plastic greenhouse) and locations where lightning often hits, connect the surge absorber to the secondary circuit of master circuit of the power distribution board. Example of surge absorber: R∙A∙V-781BWZ-4, Okaya Electric Industries Co., Ltd. (Panasonic optional part number: DV0P4190) ●Because the unit is controlled by the thyristor, it may induce electric noise to the radio receiver and wireless equipment. If this is the case, use a noise filter. Example of noise filter: SUP-EK5-ER-6, Okaya Electric Industries Co., Ltd. (Panasonic optional part number: DV0P4170) ●When the electromagnetic contactor or electromagnetic switch is used, connect voltage-surge suppressor e.g. spark killer across contacts. ● −7− For proper use ■Signal input terminal equivalent circuit Pin No.5: +24 V Internal circuit Be sure to ground the return circuit to the earth terminal: should be class D earthing 100 Ω or less, (1.6 mm or more) Should you find any discrepancy in the product, consult your local dealer.
