Refer to Appendix A for detailed information about position trans-
mitters.
NOTE: Route the wiring inside the positioner so it does not
become entangled with moving parts. A cable clamp (Figs. 3-1
and 4-1) is provided inside the positioner so entanglement can
be avoided.
4. Grounding positioners should be done in accordance with
local electrical codes (in U.S, National Electrical Code, ANSI/
NFPA 70. In Canada, Canadian Electrical Code, CSA c22.1). A
grounding screw is provided inside the enclosure for grounding,

NOTES:
1. The grounding screw located inside the enclosure is a safety
ground and should not be used to ground the shielded pair.
2. The positioner must be grounded to avoid ground loop
conditions.
