1-4 General Information MN1919
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 earth/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 : If the drive is subjected to high potential (‘hipot’) testing, only DC voltages may be
applied. AC voltage hipot tests could damage the drive. For further information
please contact your local Baldor representative.
CAUTION : Failure to meet cooling air flow requirements will result in reduced product lifetime
and/or drive overtemperature trips.
CAUTION : Violent jamming (stopping) of the motor during operation may damage the motor
and drive.
CAUTION : Operating the MicroFlex in Torque mode with no load attached to the motor can
cause the motor to accelerate rapidly to excessive speed.
CAUTION : If the drive enable signal is already present when power is applied to the
MicroFlex, the motor could begin to move immediately.
CAUTION : Do not tin (solder) exposed wires. Solder contracts over time and may cause
loose connections. Use crimp connections where possible.
