As an example, Figure 40 shows the recommended wiring necessary for the MicroFlex e100 to
control a motor, while conforming to the EMC requirements for ‘industrial’ environments.

H The M icroFlex e100 should be mounted on an earthed metal backplane.
H Ens ure cables do not obstruct airflow to the heatsink.
H Motor represents a typical Baldor BSM motor. Linear motors may also be c ontrolled by MicroFlex e100.
H Conductive shield earth/ground cl amps are not supplied.
H When using single phase supplies i t may be necessary to reverse the A C power filter - see section 3.4.7.2.
