Notes:
1) The MicroFlex e100 should be mounted on an earthed metal back plane.
2) Ensure cables do not obstruct airflow to the heatsink.
3) Motor represents a typical Baldor BSM motor. Linear motors may also be controlled by MicroFlex e100.
4) Conductiv e shield earth/ground c lamps are not supplied.
5) The threaded holes in the top and bottom of the case are for M4 bolts no longer than 11 mm (0.43 in) in length.
6) When using single phas e supplies it may be necessary to reverse the AC power filter - see section 3.4.7.2.
