5. Insert each #6-32 UNC screw into each of the module’s screw holes.
6. Using a 7/64" Allen wrench, secure the screws into position. This will secure the
mounting rails. 8 to 10 inch pounds of torque is required.
Cabling
The signals from a resolver or LDT are inherently very immune to electrical noise. However, to ensure
trouble free operation in an industrial environment, it is recommended that these cables be routed in a
separate conduit isolated from all power handling leads. A continuous uninterrupted length of cable from
the transducer to the Interface Module is preferred. If fi eld splices to the cable are required, they must
be done in an isolated grounded junction box with no other power handling leads present. Shielded cable
must be used that has similar shielding as the standard Gemco cable and the shield must not be tied to
ground anywhere along the cable run except as shown in the wiring diagram in this manual.
The cabling should also be routed away from noise generating devices like variable frequency drives,
servo amplifi ers, solenoid valves or large contactors.
