Control circuit supply (fused). Use twisted pair cable with a ferrite sleeve (see section 3.4.8).

HThe MicroFlex e100 should be mounted on an earthed metal backplane.

HEnsure cables do not obstruct airflow to the heatsink.

HMotor represents a typical Baldor BSM motor. Linear motors may also be controlled by MicroFlex e100.

HConductive shield earth/ground clamps are not supplied.

HWhen using single phase supplies it may be necessary to reverse the AC power filter - see section 3.4.7.2.
