Baldor MN735 manual To prevent equipment damage, be certain that the input power

Page 11

Caution:

To prevent equipment damage, be certain that the input power

 

has correctly sized protective devices installed as well as a power

 

disconnect.

 

Caution:

Avoid locating the control immediately above or beside heat

 

generating equipment, or directly below water or steam pipes.

Caution:

Avoid locating the control in the vicinity of corrosive substances

 

or vapors, metal particles and dust.

Caution:

Suitable for use on a circuit capable of delivering not more than

 

the RMS symmetrical short circuit amperes listed here at rated

 

voltage.

Caution:

Baldor recommends not 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:

Logic signals are interruptible signals; these signals are removed

 

when power is removed from the drive.

Caution:

The safe integration of the driver 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 this is 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:

Controls 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 driver should have

 

specifications compatible to the drive.

Caution:

Do not tin (solder) exposed wires. Solder contracts over time and

 

may cause loose connections.

Caution:

Electrical components can be damaged by static electricity. Use

 

ESD (electro-static discharge) procedures when handling this

 

control.
