2.2: Electrical Installation
The Micro-Set is designed for use in an industrial environment and incorporates extensive transient
suppression circuitry. However, the same general installation rules should be followed that are used on
all microprocessor-based equipment. Incoming AC lines should be from a clean power source and
lines carrying computer level signals should not be routed in the same conduit as high voltage, transient-
producing circuits such as variable speed drives, welders or DC switching circuits.
The 1995A PLS is only used with a single-turn resolver. Wiring for this system is shown in Fig. 11-3,
Chapter 11: Wiring Diagrams. This wiring diagram is applicable for all standard 1995 PLS’s.
2.3: Wiring Instructions
Attach the pre-wired plug on the resolver transducer cable to the transducer and route the shielded
cable through a separate grounded (earth ground) metal conduit to the panel. Connect the mating half
terminal block to the 1995A PLS. Be sure the shield wire is connected to Pin 1 of the 16-place
connector.
When extension to the factory supplied cable is necessary, a junction box should be used to connect the
wire leads and the cable shields from one cable to the other. The cable shield should be grounded at the
1995 Micro-Set only.
AC line voltage - 115V AC + 10% 50-60 Hz - should be connected to the 1995A PLS at the “AC
power” terminals on the 24-place connector.
