164 Technical data
UL marking
See the type designation label for the valid markings of your drive.
UL checklist
Input power connection – See section AC input (supply) connection on page 152.
Disconnecting device (Disconnecting means) – See section Supply disconnecting
device on page 42.
Ambient conditions – The drive is to be used in a heated indoor controlled
environment. See section Ambient conditions on page 157 for specific limits.
Input cable fuses – For installation in the United States, branch circuit protection must
be provided in accordance with the National Electrical Code (NEC) and any
applicable local codes. To fulfill this requirement, use the UL classified fuses given in
section
Supply cable fuses on page 151.
For installation in Canada, branch circuit protection must be provided in accordance
with the Canadian Electrical Code and any applicable provincial codes. To fulfill this
requirement, use the UL classified fuses given in section
Supply cable fuses on page
151.
Power cable selection – See section Selecting the power cables on page 45.
Power cable connections – For the connection diagram and tightening torques, see
section Power cable connection on page 51.
Control connections – For the connection diagram and tightening torques, see
section Connecting the control cables on page 60.
Overload protection – The drive provides overload protection in accordance with the
National Electrical Code (US).
Braking – The MicroFlex e190 has an internal braking chopper. When applied with
appropriately sized braking resistors, the braking chopper allows the drive to
dissipate regenerative energy (normally associated with quickly decelerating a
motor). Braking resistor selection is discussed in the chapter
Resistor braking on
page 171.
UL standards – See section Applicable standards on page 160.
