1010-1040, Rev. 02
• The product may be used to control an adjustable speed drive connected to high voltage sources and
rotating machinery that is inherently dangerous if not operated safely. Interlock all energy sources,
hazardous locations, and guards in order to restrict the exposure of personnel to hazards. The adjustable
speed drive may start the motor without warning.
Signs at the equipment installation must be posted to this effect. A familiarity with Auto restart settings is
a requirement when controlling adjustable speed drives. Failure of external or ancillary components may
cause intermittent system operation, i.e., the system may start the motor without warning or may not
stop on command. Improperly designed or improperly installed system interlocks and permissives may
render a motor unable to start or stop on command.
• Control through serial communications can fail or can also override local controls, which can create an
unsafe condition. System safety features should be employed and designed into the integrated system in
a manner such that system operation, even in the event of system failure, will not cause harm or result in
personnel injury or system damage. Use of the built-in system protective features and interlocks of the
equipment being controlled is highly recommended (i.e., emergency-off, overload protection, etc.).
• Never use the HMC7000 units to perform emergency stops. Separate switches outside the product, the
PLC, and the ASD should be used for emergency stops.
Changes or modifications to the MAPware-7000 program should not be made without the approval of the
system designer or systems integrator. Minor changes or modifications could cause the defeat of safety
interlocks and permissives. Any changes or modifications should be noted and included with the system
documentation.
WARNING It is extremely important that the unit and other peripherals be used for the
specified purpose and under the specified conditions, especially in applications that can
directly or indirectly affect human beings.
WARNING Do not use input functions as PT touch switches for applications where danger to
human life or serious damage is possible, or for emergency switch applications.
Safety Precautions
Please observe the following precautions when installing the unit. Failure to comply with these
restrictions could result in loss of life, serious personal injury, or equipment damage.
WARNING Do not operate the unit in areas subject to explosion due to flammable gases,
vapors, or dusts.
