Make sure these guidelines are accounted for before wiring:
All field wires must be 0.75 mm
2
or greater and comply with AS 1670.1 and the
wiring code.
Conductors must test free of all grounds.
All wiring must be done using copper conductors only, unless noted otherwise.
If shielded wire is used,
- the metallic continuity of the shield must be maintained throughout the
entire cable length.
- the entire length of the cable must have a resistance greater than 1 Megohm
to earth ground.
Underground wiring must be free of all water.
In areas of high lightning activity, or in areas that have large power surges, the
2081-9027 Transient Suppressor should be used on monitor points.
Wires that run in plenum should be in conduit.
A system ground must be provided for earth detection and lightning protection
devices. This connection must comply with approved earth detection.
Only system wiring should be run together in the same conduit.
Use supplied ferrite beads with all SPS field wiring including the Aux 24V.
Loop wires twice through the supplied ferrite bead(s) as shown in Figure 6-1.
(See Appendix K for ordering part numbers.)
