Wiring
Important points to remember about wiring:
• Always use tinned copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control wires should be separated from power wires by at least 0.3 meters
(1 foot).
• All control wires should be shielded cable with the shield earthed on one
end of the cable.
