Safety Precautions

Please read through this user’s manual before you use our product. Keep this manual handy for future reference.

Definitions used in this manual:

CAUTION! – This indicates a potentially hazardous situation that, if not avoided, can result in minor

to moderate injury, or serious damage to the product.

WARNING! – This indicates a potentially hazardous situation that, if not avoided, can result in serious

injury or death.

I. General Information

The function of the HBU braking unit is to divert into a braking resistor the regenerative energy produced in the

process of decelerating the motor, converting that energy into heat. Regenerative energy flows from the motor into the

inverter DC Bus, manifested as increased bus voltage. The advantage gained using the HBU is improved braking

performance and shorter deceleration time of the load.

Before you use the HBU braking unit, please read through this manual and please contact your distributor if you

have any questions. This manual will provide you the necessary information for installation, operation,

troubleshooting and repair of the HBU braking unit.

A. Inspection

Please check that the model number is the same as what you ordered BEFORE opening the box. Then, check the

contents for any sign of defect or damage during transport. If there is any problem, please contact your Hitachi

distributor immediately.
