Baldor BSC 7107 DC manual Be sure the system is properly grounded before

Page 7

WARNING:

Be sure the system is properly grounded before

applying power. Do not apply AC power before you ensure

that all grounding instructions have been followed.

Electrical shock can cause serious or fatal injury.

WARNING:

Do not remove cover for at least five (5) minutes

after AC power is disconnected to allow capacitors to discharge. Dangerous voltages are present inside the equipment. Electrical shock can cause serious or fatal injury.

WARNING: Improper operation of control may cause violent motion of the motor shaft and driven equipment. Be certain that unexpected motor shaft movement will not cause injury to personnel or damage to equipment. Peak torque of several times the rated motor torque can occur during control failure.

WARNING:

Motor circuit may have high voltage present

whenever AC power is applied, even when motor is not

rotating. Electrical shock can cause serious or fatal injury.

Caution:

To prevent equipment damage, be certain that the

electrical service is not capable of delivering more than the

maximum line short circuit current amperes listed in the

appropriate control manual, 120 VAC maximum per control

rating.

 

Caution:

Keep the average continuous DC current draw

under 7 amperes, and make sure the motor is rotating. A stalled brushless DC motor can quickly overheat the control and/or the motor resulting in damage to either or both devices.
