Analog Input DIP Switches
WARNING:
When using analog inputs, the DIP switches must be correctly
set and the analog inputs correctly configured before being
enabled. If this is not done, the motor may start inadvertently.
After completing settings for motor frequency and unit of measurement
DIP switches, and wiring for input power and motor connections,
reattach the I/O module.
For all versions of the SED2, the DIP switches used to configure the
analog inputs are located on the I/O module. (See Access to
Connection Terminals section for disassembly instructions.)
