Tarrytown, NY II. [. . . ] Other precautions for installation: Before installation, cover the ventilation grills on the braking unit with tape to keep out dust and metal fragments. After installation is completed, be sure to remove any tape or other coverings from the ventilation grills. Mounting clearance: Provide adequate top, bottom and side clearance around the HBU according to the following diagram: >10 cm >5 cm HBU >5 cm Figure 3 >10 cm 13 Hitachi America, Ltd. Tarrytown, NY III. The inverter DC Bus can hold a dangerous electrical charge for some time after AC power had been removed. Make sure that the inverter input power has been turned off for at least 10 minutes before you attempt to make any wiring connections to the HBU. . Wiring should be done by a licensed electrician following applicable codes and generally accepted wiring practices. Do not touch the terminals or internal components of the braking unit while the DC bus is charged. Make sure that no wire strands contact the metal case of the HBU, or cause a short circuit between the terminals. CAUTION! 1. Be sure to connect the braking resistors, braking unit and inverter according to the connection diagram. Use wire gauge > 4 mm2 on power supply connection and resistor connection. Check that the connections are correct before you connect to the power supply. Refer to the wiring diagram in Figure 4 for the necessary connections for P and N, and recommended use of fault alarm functions. The HBU-4220 also includes terminals marked R and S, which must be connected to the corresponding terminals on the AC input side of the inverter, as shown below. HBU-4220 Only R S Fault relay energizes when HBU internal temperature is too high REQUIRED FOR SAFETY Figure 4 Typical Alarm and Safety Circuit WARNING!Be sure to utilize a power disconnection method as shown in Figure 4 above, which removes power from the inverter should the braking resistor overheat. Failure to do so may result in risk of fire, injury or death. 15 Hitachi America, Ltd. Tarrytown, NY Jumper block Factory Default Position for Normally Open (N.

The wiring to the HBU should be passed through the wiring hole provided on the bottom of the unit. The wires from the HBU to the inverter and to the resistor carry high current with significant harmonic content. [. . . ] Should this occur, it would likely result in an over voltage trip on the inverter. In case of difficulty, use the table below to try to find possible solutions. Should this not resolve the problem, please contact your Hitachi distributor for further assistance. Item 1 Symptom The "POWER" light of the braking unit is not illuminated when the inverter is energized Possible Cause Wiring error HBU set for "SLAVE" Short circuit on Braking unit IGBT Solution Check the wiring Confirm that the jumper is set for "MASTER" Change the braking unit Examine the braking resistance and its connection.
