Baldor MN1274 06/2001 installation manual devices installed

CAUTION:	To prevent equipment damage, be certain that the input power has correctly sized protective
	devices installed.
CAUTION:	To prevent equipment damage, be certain that input and output signals are powered and
	referenced correctly.
CAUTION:	To ensure reliable performance of this equipment be certain that all signals to/from the drive
	are shielded correctly.
CAUTION:	Suitable for use on a circuit capable of delivering not more than the RMS symmetrical short
	circuit amperes listed here at rated voltage.
	Horsepower	RMS Symmetrical Amperes
	1-50	5,000
CAUTION:	Avoid locating the drive immediately above or beside heat generating equipment, or directly
	below water or steam pipes.
CAUTION:	Avoid locating the drive in the vicinity of corrosive substances or vapors, metal particles and
	dust.
CAUTION:	Do not connect AC power to the drive terminals U, V and W. Connecting AC power to these
	terminals may result in damage to the drive.
CAUTION:	Baldor does not recommend using “Grounded Leg Delta” transformer power leads that may
	create ground loops and degrade system performance. Instead, we recommend using a four
	wire Wye.
CAUTION:	Drives are intended to be connected to a permanent main power source, not a portable
	power source. Suitable fusing and circuit protection devices are required.
CAUTION:	The safe integration of the drive into a machine system is the responsibility of the machine
	designer. Be sure to comply with the local safety requirements at the place where the
	machine is to be used. In Europe these are the Machinery Directive, the ElectroMagnetic
	Compatibility Directive and the Low Voltage Directive. In the United States this is the National
	Electrical code and local codes.
CAUTION:	Drives must be installed inside an electrical cabinet that provides environmental control and
	protection. Installation information for the drive is provided in this manual. Motors and
	controlling devices that connect to the drive should have specifications compatible to the
	drive.
CAUTION:	Violent jamming (stopping) of the motor shaft during operation may damage the motor and
	drive.
CAUTION:	Do not tin (solder) exposed wires. Solder contracts over time and may cause loose
	connections. Use crimp connections where possible.
CAUTION:	Electrical components can be damaged by static electricity. Use ESD (electro-static
	discharge) procedures when handling this drive.
