Multi-strand cable with insulation rating of 600-1000V isrecommended.• Run the dc load and battery cables through cable glands where they pass through metalparts or covers. Also ensure that each cable gland provides firm strain relief andadequate anchorage for the cable.• Secure and support all dc load and battery cabling inside the Core Power Solutions(especially at their connection points) to prevent excessive strain on these cables.• To reduce inductive coupling, separate the dc load, battery and control cabling from theac supply cables. If the cables have to cross, run them at right angles to the ac supplycables.• In order to minimize parasitic cable inductance and reduce electromagnetic interference(EMI), route all dc load cables in close proximity to one another, and avoid large currentloops. The same applies to battery cables.• Ensure that circuit breakers/fuses in the dc distribution(s) are clearly labeled.• Only perform electrical insulation and continuity tests after all dc load and batterycabling are in place and dc common bus has been earthed.Connecting the Load and Battery Cables• Before proceeding with cable termination remove all fuses and switch off all circuit breakers.• Always check that the battery cables have been terminated to the correct system polarityBEFORE connecting the batteries or closing the battery disconnect device.• Connecting batteries to the system with incorrect system polarity will void all warranty claims.Refer to one or more of the following sections to connect the load and battery cables to thefuse and/or circuit breaker distribution(s).
