Ground and Grounding Cable Shields
Ground
Every metal DIN enclosure in a Johnson Controls installation must have its chassis
bonded to a verified electrical ground (earth).
Conduit ground, cold water pipes, unbrazed joints or dissimilar metals
are unacceptable in the path of either building or supplemental
ground. Where grounding is required, connect only to the proven
building electrical system ground (earth).
