Remove the two attachment screws at the bottom of the cover by turning counterclockwise. Remove the cover by lifting it upward from the bottom. (Figure 2 A) 2.
- Page 13 Hitachi America, Ltd. Tarrytown, NY 2. Ambient temperature: In order to improve the life and reliability of the braking unit, please install it in a well-ventilated area. If you install braking units in an enclosure, be sure to size the panel properly and provide adequate cooling/ventilation as necessary to ensure the internal temperature remains lower than +40˚C.
- Page 14 Hitachi America, Ltd. Tarrytown, NY III. Installation and Operation WARNING! 1. 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..
- Page 15 Hitachi America, Ltd. Tarrytown, NY On 200 V models, the activation voltage is fixed at 380 VDC. 6. When using multiple HBU units, please refer to section III, B on page 16. The first braking unit should have its jumper set to the MASTER position, and braking units number 2 through N should have their jumpers in the SLAVE position.
