Baldor Baldor, MN850 manual Safety Notice, Precautions

Safety Notice	This equipment contains voltages that may be as high as 600 volts! Electrical shock can
	cause serious or fatal injury. Only qualified personnel should attempt the start-up
	procedure or troubleshoot this equipment.
	This equipment may be connected to other machines that have rotating parts or parts
	that are driven by this equipment. Improper use can cause serious or fatal injury. Only
	qualified personnel should attempt the start-up procedure or troubleshoot this equipment.

PRECAUTIONS

WARNING: Do not touch any circuit board, power device or electrical connection before you first ensure that power has been disconnected and there is no high voltage present from this equipment or other equipment to which it is connected.

Electrical shock can cause serious or fatal injury.

WARNING: Be sure that you are completely familiar with the safe operation of this equipment. This equipment may be connected to other machines that have rotating parts or parts that are controlled by this equipment. Improper use can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment.

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.

Caution:	Install MOV protection for the control. See Appendix D for information.
Caution:	Do not remove keypad cable with power applied to unit. Disconnecting the keypad
	cable with power applied will damage the control.
Caution:	Shearpin trip feature is not equivalent to short circuit overcurrent protection
	required by NEC. Instantaneous overcurrent protection must be provided by
	circuit interrupting device (fuse or breaker).
Caution:	Suitable for use on a circuit capable of delivering not more than the RMS
	symmetrical short circuit amperes listed here at rated voltage (with fuses specified
	in Section 2).
	Rated Amperes	RMS Symmetrical Amperes
	9–59	5,000
	72–242	10,000
	300–500	18,000
	600–750	30,000
	900–1200	42,000
Caution:	Do not “Megger” test the motor while it is connected to the soft–start control.
	Failure to disconnect motor will result in extensive damage to the control. The
	control is tested at the factory for high voltage / leakage resistance as part of
	Underwriter Laboratory requirements. Do not megger any part of the control.
Caution:	Do not connect power factor correction capacitors to motor terminals. If power
	factor correction capacitors are necessary, contact Baldor.
Caution:	If a brake motor is used, the initial starting voltage may not be sufficient to release
	the brake. It may be necessary to provide separate power for the brake release
	coil.
Caution:	Do not connect AC incoming line power to the Motor terminals T1, T2 and T3.
	Connecting AC power to these terminals may result in damage to the control.
