2-2 Installation
General Precautions In addition to the precautions listed throughout this manual, the
following statements, which are general to the system, must be read
and understood.
Heat Dissipation The following table provides the maximum heat dissipation at rated
current for the controllers. For currents lower than rated value, heat
dissipation will be reduced.
Table 2.A Maximum Heat Dissipation
Enclosures The open-style design of the SMC-Flex controller requires that it be
installed in an enclosure. The internal temperature of the enclosure
must be kept within the range of 0…50°C.
ATTENTION
!
The controller contains ESD- (electrostatic
discharge) sensitive parts and assemblies. Static
control precautions are required when installing,
testing, servicing, or repairing the assembly.
Component damage may result if ESD control
procedures are not followed. If you are not familiar
with static control procedures, refer to applicable
ESD protection handbooks.
ATTENTION
!
An incorrectly applied or installed controller can
damage components or reduce product life. Wiring
or application errors, such as undersizing the motor,
incorrect or inadequate AC supply, or excessive
ambient temperatures, may result in malfunction of
the system.
ATTENTION
!
Only personnel familiar with the controller and
associated machinery should plan or implement the
installation, start-up, and subsequent maintenance
of the system. Failure to do this may result in
personal injury and/or equipment damage.
ATTENTION
!
Hazardous voltages that can cause shock, burn, or
death are present on L1, L2, L3, T1, T2, T3, T4, T5,
and T6.
Power terminal covers can be installed to prevent
inadvertent contact with terminals. Disconnect the
main power before servicing the motor controller or
associated wiring.
